Amino acids are the basic unit of protein composition, most of the amino acid processes are through fermentation method. filtration of fermentation broth is an extremely complex system and contains microbial cells, metabolites, unconsumed medium, etc.

The traditional method of amino acid production processes such as centrifuge and plate and frame pressure filtration, the filtrate quality is poor. Soluble protein, sugar, peptide, pigment and other impurities can not be effectively removed, increasing the processing load of the subsequent process, affecting overall yield of the extraction process, also affecting quality of final product.

Amino acids: lysine, glutamic acid, phenylalanine, threonine, tryptophan, glycine, arginine, glutamine, theanine, proline, valine, isoleucine

Ceramic membrane integrated organic membrane filtration process system has the unique advantages of high separation precision, maintaining high-throughput filtration and high product yield, less waste water, less cleaning frequency, without adding additives and achieved desalination and preconcentration of the target product which has been successfully applied to bio-fermentation enterprises such as glutamic acid production (sodium), lysine production, threonine production, tryptophan production, valine production and so on compared with traditional process.

Process features

Compared with traditional separation process, the quality of the filtrate is guaranteed due to high separation accuracy and uniform pore size distribution; high-throughput filtration can be maintained, and cleaning frequency is reduced because membranes have smooth surface to result in membrane flux slowly decay; Improve product yield, reduce the amount of wastewater, pore size diversification, suitable for different types of materials processing requirements;

Without adding additives, concentrated material (mycelium, protein, etc.) can be used as feed recovery;

95% of fermentation of bacterial cells integrity and activity can be guaranteed;

Organic membrane filtration is used to to remove small molecules protein or peptides, nucleic acids, dyes and other impurities from permeation generated by ceramic membrane and improve product purity and reduce sewage treatment load;

Achieve the desalination and preconcentration of the target product, and reduce the production load of subsequent processing technologies such as solvent extraction, ion exchange and evaporation concentration.

 Xanthan Gum

Xanthan gum is a polysaccharide with a wide variety of uses, including as a common food additive. It is a powerful thickening agent, and also has uses as a stabilizer to prevent ingredients from separating.

Xanthan gum is known as "industrial MSG", is the largest and widely used microbial polysaccharide in the world at present.

Use of membrane filtration and separation operations allows concentration and purification of substances such as xanthan with recycling of permeate. It also provides an inexpensive and reliable way to remove water and low molecular weight impurities. Fractionation, concentration, and purification of gelatins via membrane operations result in gentler processing to avoid denaturing the gelatine.

 Vitamin

Vitamin C production has two fermentation processes: Reichstein method and two-step fermentation. Impurities in fermentation broth are removed by the use of heat precipitation method for the above two traditional vitamin C extraction process. After the fermentation broth was allowed to settle, it was separated by a cation exchange resin. However, the fermentation broth is passed directly through the ion exchange resin, which can cause serious contamination of the resin surface and reduce the exchange capacity.

Modern extraction process generally applies ultrafiltration membrane gulonic acid fermentation broth production, because the broth protein molecular weight range is generally 1-10kDa, so to choose a certain molecular weight cut-off can remove most of the protein and some macromolecular impurities in place of the traditional heating method to remove protein.

vitamins

Compared with the traditional process, Gulonic acid fermentation broth has obvious advantages: simple process, fully automatic operation and good stability; the yield is improved, generally reach more than 99% during membrane filtration for removing impurities. At present, integrated membrane technology including ceramic membrane, ultrafiltration & amp; nanofiltration membrane is applied to vitamin C production enterprises because membrane process has more important feature is the separation of relatively high accuracy, which can be verified from the fermentation broth protein removal rate.

Vitamins: Vitamin C, vitamin B2, vitamin B12 and so on

Threaded Magnets

Mounting magnets are comprised of powerful permanent magnets set inside steel cups or channels with countersunk holes or threaded features for holding applications. The steel structure redirects the magnetic field from the back-side of the magnet, making it much more stronger in terms of pull force, and protects the magnetic material from damage during use. Commonly used mounting magnets include Hook Magnets, threaded rod magnets, Countersunk/Counterbore Pot Magnets, Channel Magnets and Rubber Coated Magnets.

Mounting Magnets can double the strength of which you get with the magnet alone, as the steel cup attracting to it is magnetized by the magnet, giving much more pull force. The pull force numbers we list for each product is the force required to pull the mounting magnet straight away from a steel surface.

In fact, how much force a mounting magnet can hold depends on a few factors. When loading the magnet in a different orientation, for example, vertically stuck onto a wall, the weight it can hold up is usually lower than the listed pull force number. Moreover, the friction between the surfaces, the shape of what is being held up, and other factors also contribute to differences of the results.  

Powerful mounting magnets are often used as fishing magnets to retrieve objects that are lost underwater with magnetic parts or steel components. Mounting magnets with different features, such as hook, threaded and countersunk, can be widely used for holding, hanging, and attaching objects in different projects.

Today's society has higher and higher requirements for the quality and safety and reliability of energy and power supply. The traditional large-grid power supply method cannot meet this requirement because of its own defects. A new type of power grid capable of integrating distributed power generation – micro-grid emerges as the times require. It can save investment, reduce energy consumption, improve system safety and flexibility, and is the future development direction. Capacitance plays an important role as an indispensable energy storage system in the microgrid. As a new type of energy storage device, supercapacitor has become one of the preferred devices for microgrid energy storage with its irreplaceable superiority. The microgrid consists of micro power supplies, loads, energy storage, and energy managers. The form of energy storage in the microgrid is: connected to the DC bus of the micro power supply, the feeder containing the important load or the AC bus of the microgrid. Among them, the first two can be called distributed energy storage, and the last one is called central energy storage. When connected to the grid, the power fluctuations in the microgrid are balanced by the large grid, and the energy storage is in the charging standby state. When the microgrid is switched from grid-connected operation to isolated network operation, the central storage energy is immediately activated to make up for the power shortage. The fluctuation of the load during the running of the microgrid or the fluctuation of the micro power supply can be balanced by the central energy storage or the distributed energy storage. Among them, there are two ways to balance the power fluctuation of the micro power supply, and the distributed energy storage and the micro power supply that needs energy storage are connected to a certain feeding line, or the energy storage is directly connected to the DC bus of the micro power supply.

1) Provide short-term power supply

There are two typical modes of operation in the microgrid: under normal circumstances, the microgrid and the conventional distribution network are connected to the grid, which is called the grid-connected operation mode; when the grid fault is detected or the power quality is not met, the microgrid will be timely The grid is disconnected and operated independently, called the isolated mode. Microgrid often needs to absorb some of the active power from the conventional distribution network. Therefore, when the microgrid is switched from the grid-connected mode to the isolated mode, there will be power shortage. Installing the energy storage device will help the smooth transition of the two modes.

2) Used as an energy buffer

Due to the small scale of the microgrid, the inertia of the system is not large, and the network and load often fluctuate very much, which has an impact on the stable operation of the entire microgrid. We always expect high-efficiency generators (such as fuel cells) in the microgrid to always operate at its rated capacity. However, the load on the microgrid does not remain constant throughout the day. Instead, it fluctuates as the weather changes. In order to meet the peak load supply, peak load adjustment must be carried out using a fuel-and-gas peaking power plant. Due to the high fuel price, the operation cost of this method is too expensive. The supercapacitor energy storage system can effectively solve this problem. It can store the excess power of the power supply when the load is low, and feed back to the micro grid to adjust the power demand when the load is high. The high power density and high energy density of the supercapacitor make it the best choice for handling peak loads, and the use of supercapacitor requires only the storage of energy equivalent to the peak load.

3) Improve the power quality of the microgrid

The energy storage system plays an important role in improving the power quality of the microgrid. Through the inverter control unit, the reactive power and active power provided by the supercapacitor energy storage system to the user and the network can be adjusted, thereby achieving the purpose of improving the power quality. Because supercapacitors can quickly absorb and release high-power electric energy, it is very suitable to be applied to the power quality adjustment device of the micro-grid to solve some transient problems in the system, such as instantaneous power failure and voltage swell caused by system failure. Problems such as voltage dips, etc. At this time, supercapacitors are used to provide fast power buffering, absorbing or supplementing electric energy, and providing active power support for active or reactive power compensation to stabilize and smooth fluctuations in grid voltage.

4) Intelligent distributed grid system supercapacitor is essential

From the perspective of the future development of smart grids, intelligent distributed grid systems will be the mainstream of future grid systems. In order to realize the construction of the intelligent distributed power grid system, it is necessary to have a buffer device such as a distributed energy storage device and a central energy storage device. In the case of unstable energy production processes, a buffer is needed to store energy. In the case where the process of energy generation is stable and the demand is constantly changing, it is also necessary to use an energy storage device. A fuel cell is different from wind or solar energy, and as long as it has fuel, it can continuously output stable electric energy. However, load demand varies greatly over time. If there is no energy storage device, the fuel cell will have to be large to meet the peak energy demand, and the cost is too high. By storing excess energy in the energy storage device, it is possible to provide the required peak energy through the energy storage device in a short time.

In distributed grid systems, the transient impact of power systems is inevitable, and the superior performance of supercapacitors can reduce the impact of transient impact on overall system performance. Therefore, in the future intelligent distributed grid system, the ultracapacitor bank energy storage system is indispensable.

Kamcap is a supercapacitor manufacturer in China. The company has introduced professional automatic testing equipment such as kamcap supercapacitor, automatic casing machine, laser welding machine. If you want to know more  application of supercapacitor, you can call us and rest assured of our supercapacitor safety.

Glasgow in Trip UK posted April 24, 2020

How many days in Glasgow?

Glasgow is a quite small city. Should we stay one, two or three days on-site?

You could spend a weekend there to be able to appreciate the city. And three days seems to be the ideal duration! (Excluding transport).

Check the trains to Glasgow.

Why visit Glasgow?

At first glance less attractive than its big sister Edinburgh, Glasgow is a city more suited to "short" stays. More accessible (check the trains to Glasgow), smaller, but just as exotic!

Glasgow's "attractions" will appeal to as many people as possible, be it architecture, art or cuisine. There are lots of things to see and do (and eat the famous Haggis )! It is, therefore, an accessible city, on a human scale, pretty, and full of good things. A perfect place to spend a weekend!

Definition of anti staining agent

Anti staining agent is a substance that can prevent dyes from coloring in fabrics or in the dyeing and printing process.

Classification of anti staining agent

Anti staining agents can be divided into two categories according to their mechanical and chemical properties. The former has the wax, oil and some inorganic compounds, the latter including acids, bases, salts, oxidants, reductants, etc. There is one special anti staining agent, such as phenylhydrazine sulfonic acid. Some of them are coated on fabrics to prevent contacting with fiber, such as paraffin, turpentine, starch, clay, and barium sulfate. Some anti staining agents take functions by working with the dyes, to invalidate the dyes or to produce precipitates, such as lime, lead sulfate, aluminum sulfate, calcium phosphate, etc. There are also anti stain salts.

Advantages of anti staining agent

1. Good anti staining effect, and give the original white cotton fiber anti-indigo or vulcanized dyestuff stain
2. Excellent dispersion performance. It can be used in the same bath with mycin and most other auxiliaries
3. Stable during the process of acid or neutral stone washing

As the saying goes decoration is good or not , the kitchen is representative. The meaning of the kitchen to the home is , has a kitchen , the living day is vivid

But the kitchen is a very difficult place to clean, because of it;s nature of its use.

For example,the accumulation of oil

So Snimay reminds everybody here: plan carefully before decorating a kitchen, can save a lot of unnecessary trouble that uses in the future! So what kind of kitchen is an outstanding kitchen?

Moving line is reasonable, each district is distinct.

The most common layout of kitchens in general can be divided into the form of I-shaped, L-shaped, T-shaped, U-shaped, island-shaped, etc. No matter what kind of layout, you should try to follow the "triangular principle" of kitchen work, that is: The working lines of picking, cleaning and cooking are smooth and not crowded, that is, the moving lines are reasonably distinguished from each other.

I-shaped is more suit the small family kitchen with long and narrow space and independence, set freezer → clean arrange area → cook area layout arrangement;

U-shaped suits a space more big and capacious kitchen door model, can set the triangular layout that provides refrigerator, sink, stove.

L-shaped is more suit the family that has strong storage need, normally moving line can divide into washing area, cutting area. Cooking area, convenient to move, easy to operation.

Cleaning area and cooking area must reserve a preparation area, so as to ensure smooth enjoyment of cooking life.

The kitchen storage is to keep the kitchen neat the most important one respect, the thing that can see must be a little, clever and quick hide just neat.

All kinds of cutting board, pallet and barbecue iron rack, vertical storage is not only to save space, but also conducive to ventilation and drying.

After washing, cut the vegetables in the preparation area, so place the knife rest in the preparation area to facilitate cutting the food.

Place a dish rack next to the cleaning area is really important . Refuse to get wet everywhere!

After starting of cooking, the basket that next to the cooking area is easy access to spices and cooking tools;

Use in the kitchen to receive commonly used scissors, peeler, clingfilm to wait, very good.

The hot items in these niche watch brands are relatively cheap. Not only can they look good and have a texture, but you also don't have to worry about being the same with others, the key point is to highlight your unique taste.

618 big sales are coming. It is a good time to change the watch. Many people are asking if there is any cost-effective watch recommendation. Watches are the best choice to show one's personal taste. How to buy a watch and what style of watch to buy is probably a tangled problem for many people.

Before buying a watch, you need to know this introductory knowledge in order to choose a cost-effective watch. Otherwise, buying a watch with confusion is very painful. Today we are going to talk about what introductory knowledge we need to know before buying a watch.

1.Common watch types

There are machinery, quartz, light kinetic energy, radio waves. Mechanical watches are mainly divided into two types of manual winding and automatic winding.

Manual winding requires manual twisting of the mainspring as power, and the thickness is generally thinner than that of automatic winding, and the weight will be relatively large. The automatic mechanism also retains the function of manual winding, but there is an internal oscillating rotor that can turn the winding. Only the movement of the wrist can bring continuous kinetic energy to the watch.

Quartz watches are thinner than traditional mechanical watches, and the time is more accurate. At the same time, they don’t need to be wound frequently. When moving, the second-hand jumps every time. A battery can generally be used for two or three years. The price is much cheaper than mechanical watches.

The light kinetic energy meter can absorb the visible light source into the kinetic energy of the watch. It is more environmentally friendly. It can run in the dark for more than 100 days after being fully charged, and the time is accurate. The life of the rechargeable battery is generally more than 10 years.

Electric wave table, a watch that can automatically calibrate the time after the electric wave of the calibration information, the electric wave table's error will not exceed 1 second for hundreds of thousands of years.

It is recommended that if you are buying a mechanical watch for the first time, you can choose an entry-level mechanical watch that is cheaper, you can experience the mechanical watch first, have a certain feeling for the mechanical watch, and then buy big and famous watches step by step.

2.Remember to waterproof on the watch

3ATM or 30 meters waterproof refers to the general life waterproofing, which is the water droplets splashed when washing hands, and the raindrops that fall when there is raining.

5ATM or 50 meters waterproof, it means that it is suitable for short-term swimming in shallows, not for diving or snorkeling. 10ATM or 100 meters waterproof, it can be used to wash cars and showers, but not soaked in water. 30ATM or 300 meters waterproof, can swim, but only for shallow swimming.

All watches are not "steam-proof". You can wear a waterproof watch to take a shower, swim, wash dishes, and wash your hands, but you can't wear a watch to take a hot bath. Once the steam enters the movement, the parts are rusted and the time is not accurate, and the watch is basically scrapped.

3. Understand the watch material

The most widely used is stainless steel, which will not be eroded and rusted by sweat. The ceramic material is comfortable and wear-resistant, but the disadvantage is that it is easy to break. The material of the table mirror and the see-through cover is generally sapphire crystal glass, which is second only to diamond in hardness 9 and its characteristics are relatively wear-resistant and not easily be scratched.

When choosing a watch, you can determine its value and whether it has an allergic reaction to yourself based on the material made.

Have you ever have thing buy from taobao, the taobao online shop is more and more wide use in nowadays.welcome to use it.

As the Internet develops faster and faster, people are increasingly inseparable from computer work, which means that printers are used more frequently. As an essential part of the printer, ink plays a great role in the process of document output. The printing effect of high-quality ink is pretty good, but it does not mean that as long as you have good-quality ink, nothing else matters. There are still many factors need to be considered.

1.Original ink is important

The characters printed by the original ink are clear and sharp, with rounded edges and no ink splashing. The image is more three-dimensional, with long-lasting color, and it is not easy to fade. At the same time, the use of original ink is more cost-effective, and the print quality is more outstanding without damaging the printer.

2.Fake ink is harmful

Ink is a consumable item, and it must be purchased at intervals. As a result, some unscrupulous merchants have an opportunity to manufacture counterfeit and shoddy inks and attract customers to buy with low prices. Many poor quality inks not only have extremely poor printing results, but also threaten human health.

In order to reduce the cost of making low-cost inks, cheap chemical industrial fuels are used, which emit toxic gases and dust during use, which is extremely harmful to human health. Therefore, in a situation where both “good quality” and “cheap price” are incompatible, choosing “good quality” is a guarantee of work and a commitment to health.

3.Save ink by printing according to demand

The ink consumption of the printer is proportional to the print quality and resolution, and you should choose to print according to your actual needs. For files that do not require high color printing, you can use the “text” mode to reduce the print quality and save ink; for files that require higher color quality, setting the screen properties can not only save ink, but also effectively increase the printing speed.

 When buy printer ink, you must purchase it through regular channels, so that you can choose a high-quality ink and work more efficiently.

1. Entry-level individual users

Generally speaking, we should first pay more attention to economic practicability and ease of use, instead of chasing too high resolution. Even for image processing enthusiasts, a resolution of 600dpi can meet the basic requirements. In terms of ease of use, attention should be paid to whether there is a detailed installation and use manual attached, whether the scanning software interface is easy to understand and to set various options, whether there are some convenient function keys designed, etc.When buying, see whether the color style of the scanner is suitable for one's own aesthetic habits. Choosing a satisfactory appearance, volume and style can well decorate the family environment.

2. Ordinary office users

If you are an ordinary office user, the purpose is very clear, that is to scan faster. Therefore, when purchasing, more attention should be paid to the scanning speed of the scanner and whether it is equipped with a paper feeder, which is conducive to the automatic continuous scanning of manuscripts. In terms of resolution, about 1200dpi can meet almost all the requirements. As for color, it is not as high as that of professional users because of the common color deviation of computer screens. In addition, the ease of use and intelligent design of the scanner are equally important to ordinary office users. Humanized design can save some complicated scanning steps, especially for users who often need batch scanning.

Handheld book scanner

3. Professional users

Users who are engaged in professional image processing in graphic design, advertisement production, printing and typesetting and other fields have high-end requirements on all aspects of scanner performance, especially the scanning effect, which requires color restoration, clarity and level to be higher than that of ordinary scanners. When purchasing a scanner, in addition to paying attention to high hardware color bits and high resolution (generally above 1200dpi), you should also know another important parameter of the scanner: dynamic density (this parameter is generally less than 2.0 for ordinary scanners). The higher the dynamic density, the stronger the scanner's hierarchical performance. It is generally necessary to scan films, negatives and other transparent manuscripts. Since the storage space occupied by higher resolution scanning pictures is certain, if the scanner is equipped with a faster SCSI interface (or IEEE 1394), the data transmission time can be greatly shortened and the work efficiency can be improved. Thus the requirements for volume, weight and appearance characteristics are not important.

4. Comprehensive guidance

The restoration degree of an original image by a scanner is not only related to the above resolution, but also affected by the color depth and gray scale. The scanning speed is closely related to system configuration, scan resolution setting, scanning size, magnification, etc. Fast scanner speed is important, but the image quality cannot be affected by improving the speed. Some scanners with very fast scanning speed will lose some image information during scanning. Therefore, you must try to scan it yourself before making a formal purchase. It is best to bring along some different scanned originals, such as photos, printed images, newspaper text, etc. At the same time, you can also try to scan some objects, such as keys and cigarettes, to see if the effect is satisfactory.

Projector is used more and more widely, not only in some business occasions, but also in many people's home film systems. But most people don't care much about how to use the projector correctly.

In fact, there will be many small problems in the use of the projector. In addition to the basic installation and maintenance, there will be some puzzling occasion in the use of the projector, which will make the user misunderstand the projector. Today, I'll explain the common problems that the projector occasionally has, so that users won't be too flustered in the use process.

The first is about sound.

Many users will be confused about the sound when using the projector. The speaker of the projector is very small. The main function of the projector itself is to show the perfect picture, and the loudspeaker takes up too much internal space, so the loudspeaker design of the projector will be relatively small, so it is better to cooperate with the external sound equipment when using the projector. At present, most of the projectors on the market are equipped with sound output terminals, which is also fully prepared for the external sound equipment.

Secondly, the brightness of the projector.

Many users responded that the projection screen was not as bright as before after the projector was used for a period of time. They asked if there was a quality problem with the projector. Actually not. At present, most projector products use the built-in bulb penetration projection mode, and the projection brightness is mainly determined by the bulb, while the display brightness of the projector's bulb is inversely proportional to its use time. Generally speaking, after 120 hours of use, the brightness of the bulb will drop by 20% - 30%. Therefore, users must pay attention to protecting the projector's bulb in normal use. Do not use it for a long time. Try to turn off the projector when not in use.

Finally, the problem of the picture.

Sometimes the projector has the state that image is unstable state, or the picture blurs and shakes. This is also not a problem with the projector function. Some tips are needed to solve it. First look at the image instability.

The output image of the projector is unstable and has stripe fluctuation, which is mostly due to the inconsistency between the power signal of the signal source and the power signal of the projector. The user needs to plug the power of the projector and the signal source into the same terminal block, which can basically solve this problem.

The condition of blurred and dithering picture. Generally speaking, if the projector is too far away from the signal source, it will weaken signal, and the performance projected on the screen can be blurred or dithered. So when using the projector, it is noted that the distance between the signal source and the projector can not be too large. If the distance between the two is large, it is recommended to use a signal amplifier to help the projector receive the signal from the signal source.

The projection gauze, which is generally not used as a fixing device for performance venues, is a translucent curtain made of thin cotton cloth or chemical fiber with reticulated holes. It is widely used for the holographic projection or gauze projection. Projection gauze as a special screen is most applied for the live holographic 3D digital projection, interactive holograms, and other types of holographic displays.

Gauze holographic screen can be extremely fine barbed wire mesh, can also be not easy to be seen by the naked eyes of meticulous gauze and so on. Different materials and colors also make them different in effect, which based on the effect of the holographic displays.

Analysis on the Application of gauze screen projection Technology in holographic projection

With its characteristics of light transmittance, lightness and high degree of color reduction, gauze screen can be described as a great display in the creative presentation of multimedia dance images, which not only helps dance images to create virtual and realistic visual scenes, but also expands the level of stage space. It strengthens the interaction between the actors and the images in the performance and adds a lot of color to the whole performance.

 The application of holographic projection

1. Holographic projection to create virtual realistic scene

Because of the light transmittance of the projection gauze, the transparency of the screen can be changed by adjusting the projection point of the light source to form a secondary imaging, looming actors and images, and form a kind of dreamy virtual scene. Casting light from the front to the gauze can show the image painted on the gauze; when the light is cast from the back of the screen to the gauze, the image drawn in front of the screen appears to cease to exist. To a great extent, it enhances the stage tension of the performance and makes the audience feel the magical world brought about by multimedia dance images.

2. Holographic projection to expand the level of stage space

The light and thin folding of the gauze makes it get rid of the fixed shackles in use, and it can be suspended in front of the stage, in the middle, and so on, and the tilt angle of the gauze can also be determined by the projection angle. The imaging medium composed of gauze can provide a good response of imaging visual effect. Compared with the traditional projection screen, the projection gauze greatly expands the level of stage space.

3. Holographic projection enhances the interactivity of the performance

The audience can see the object on the back of the screen through the gauze, and its light transmittance can be used for secondary imaging, which is more transparent than the traditional projection screen. Gauze projection shortens the distance between the audience and the performer, enhances the interaction between the performer and the audience, integrates the multimedia dance images from the performance into the performance, and makes the performance more complete.

DLP is the abbreviation of "DigitalLightProcessing", i.e. digital light processing. That is to say, the image signal should be processed digitally before the light is projected. It is based on the DigitalMicromirrorDevice (DMD) developed by TI (Texas Instruments) company to display the visual digital information. Specifically, DLP projection technology uses DMD as the main processing element to realize the digital optical processing.

DMD chip is an extremely accurate optical switch device. It can reflect light through micro mirror matrix and form projection, which can digitally modulate light. In DLP orthographic projection system or HDTV, red, green and blue light alternately irradiate the lenses, which are turned on or off according to the video or graphics signal fed into the bottom memory chip. Lenses are switched on and off more than thousands of times a second; the light they reflect passes through the lens and reaches the screen to produce images.

LIn projectors for high brightness applications, three DLP chips are used - green, red and blue, respectively. The light generated by the lamp will be separated into these three colors by the prism, and then directed to the corresponding DLP chip. Then, the reflections of the corresponding pixels on each DLP chip are recombined to generate the image.

The single-chip DMD system used in DLP TV, home theater and small media projector consists of a DMD chip, a light bulb, a color wheel and a projection lens. These devices can well generate sharp and colorful video and images in theaters and some large places. A 3-piece DLP system has more realistic colors and higher brightness. In a 3-chip DLP system, white light is divided into red, green and blue light through prism. These three colors correspond to one DLP chip, and the colored light reflected by each DLP chip will be mixed together to generate a pixel on the screen through the projection lens. DLP cinema system can generate more than 35 trillion colors, bringing unparalleled visual experience.

With DLP technology, commercial projectors, home theater systems, high-definition TVs and large venue projectors can provide incredibly clear and sharp images. It is a digital technology, so DLP projection system can always maintain excellent performance in the service life of the projector, thus bringing unimaginable reliability for display electronic products. Moreover, DLP technology is based on semiconductors, and its lightweight characteristics enable manufacturers to develop smaller, lighter and better products than other technologies. Portable projectors with DLP technology can currently provide 2000 lumens or higher output with a total weight of two pounds.

Picking out the best projector can definitely become a headache for many. People usually think that going to a showroom and browsing projectors at a time can be tiring as you don’t have enough knowledge about the topic. However, you need not worry about anything. Here we present you the ten best ways to pick the right projector for you:

PICK THE PROJECTOR THAT CURBS YOUR REQUIREMENTS

To be precise, there are three kinds of projectors in the market, namely Home Theater Projectors, Business Projectors, and Pico Projectors. Home Theater Projectors usually project wider content and emphasize on image quality and high contrast as they are fit for in-home use. Business Projectors are meant for projecting ppts during Business Meetings and Conferences. On the other hand, we have Pico Projectors that are generally used for gaining portability as you can carry them wherever you go. Make a wise choice as per your requirements.

PICK THE PROJECTOR OF THE RIGHT TYPE

The three most general types of projectors are DLP projectors, LCD projectors, and LCoS projectors. DLP projectors are lightweight and are good for having a smooth projection of video content that can project fast-action scenes with ease. LCD projectors are generally brighter whereas LCoS usually cover everything.

PICK THE PROJECTOR WITH GOOD LIGHT SOURCE

Projectors typically use a standard lamp, laser, or LED for light projection. It is often recommended that you opt for LED projectors instead of ones with a standard lamp. The laser projectors are energy efficient and offer better outputs too, but still LED ones are safer for the eyes.

PICK THE PROJECTOR WITH THE PERFECT ASPECT RATIO

The aspect ratio plays a significant role in achieving the drool-worthy picture quality of a good projector. You may find a lot of attractive projectors in the market. However, very few of them manage to project good quality video content on the big screen. Even though 4:3 projectors are cheaper, 16:9 are better for high picture quality.

PICK THE PROJECTOR WITH THE RIGHT RESOLUTIONS

Yet again, the debate about getting high quality projected video content continues. The resolutions of the projector vary in accordance with the aspect ratio. For 4:3, we have SVGA (800x600) and XGA (1024x768). On the other hand, for 16:9, we have standard HD (1280x720), WXGA (1280x800), and Full HD (1920x1080). 16:9 and Full HD make up for a great combination for achieving high quality projected video content.

PICK THE PROJECTOR WITH THE GOOD BRIGHTNESS

Brightness plays a significant role in the projection of video content. A projector with good brightness can make up for a great video watching experience for the user. Remember that brighter the light, the better the color. The vibrant color won’t impress you unless they are cast in a more colorful frame. Especially for business Projectors, you must have high brightness.

PICK THE PROJECTOR WITH THE REQUIRED CONTRAST RATIO

It is the difference between the darkest and brightest areas of your projected video content. For getting better details out of your projected video content, a good projector must have a defined contrast ratio that can highlight the presence of shadows, in turn, enhancing the picture quality. You’ll know the worth of contrast ratio mostly while projecting video content in darker rooms.

PICK THE PROJECTOR WITH EXCELLENCE THROW RATIO & LENS ZOOM

Throw ratio is critical at times when you are planning to mount the projector right as it decides how much wide image is going to be cast on the screens. In such cases, short-throw projectors are the best as even if the projector is closer to the screen; a wide image will be cast on the screen. The lens zoom avails the user to adjust the size of the screen which can help you out if you have a pico projector in your vicinity.

PICK THE PROJECTOR WITH THE PRODUCTIVE CONNECTIVITY OPTIONS

You might find the need of connecting external devices to your projector now and then. In such cases, you should have the productive ports that can avail you to connect external devices to your projector. Therefore, you must confirm that the projector has important ports such as USB port, HDMI port, VGA port, SD card slot and other ports that should be present for allowing you to connect the devices you own with the projector you’re about to buy.

PICK THE PROJECTOR WITH NICE FEATURES

Features such as Keystone Correction and Lens Shift might help you a lot in enhancing your experience while using a projector. These features will help you in deciding the screen orientation and adjust the image on projectors with ease. In addition to these, you can also opt for projectors that support 3D technology as in the end having a good experience while using your projector is all that actually matters. Wireless projectors and adapters are a good option as well.

This is it for now. Have a fun time choosing the right projector for you!

Brightness is the light intensity that the projector product outputs to the screen, and also the brightness of the projected image. In general, the higher the brightness of the projector, the brighter the image of the same size projected on the screen, and the clearer the image. However, the brightness of the image that our eyes can perceive is not only determined by the brightness of the projector, but also greatly related to the intensity of the ambient light and the size of the image. The stronger the ambient light, the dimmer the brightness of the image perceived by our eyes. Therefore, users must choose the appropriate brightness according to the environmental conditions of their projector. It is not necessarily as bright as possible. In the case of the same other indicators, the higher the brightness is, the higher the price of the projector will be. At the same time, the brightness of the image perceived by our eyes will have a certain range. Beyond this range, the our eyes will feel uncomfortable, especially after watching the image with high brightness for a long time. Our eyes will feel tired and may get hurt to some extent.

It is necessary to remind the user that in addition to choosing the brightness index according to the space size, the user should also consider the lighting conditions of the use environment, screen type and other factors. Under the same brightness, different ambient light conditions and different screen types will produce different display effects. When users choose projector products, they should have a margin for brightness index. Because the brightness of the projector largely depends on the light bulb in the projector, the brightness output of the light bulb will decline with the use time, which will inevitably cause the brightness of the projector to be declined. After 2000 hours of use, the brightness of the projector product decays rapidly, so when users choose the projector product, they must have a comprehensive consideration of the brightness index.

Generally speaking, in the 40-50 square meters of home or reception hall, it is recommended to choose 800-1200 lumens for projector brightness, and 60-72 inches for screen; in the 60-100 square meters of small conference room or standard classroom, it is recommended to choose 1500-2000 lumens for projector brightness, 80-100 inches for screen; in the 120-200 square meters of medium conference room and ladder classroom, it is recommended to choose 2000-3000 lumens for the brightness of the projector, and 120-150 inches for the screen; in large conference rooms or auditoriums with an area of 300 square meters, professional engineering machines with an area of more than 3000 lumens should be selected most projectors, and the screens should be more than 200 inches.
