With the development of science and technology, people's requirement for parts processing quality is becoming higher and higher. At the same time, product modification is frequent. In general mechanical processing, single and small batch products account for an increasing proportion. In order to ensure product quality, improve productivity and reduce costs, machine tools are required not only to have good versatility and flexibility, but also to have a high degree of automation in the process of processing. cnc machining technology is a kind of high-efficiency and flexible automatic processing technology developed under this environment, which is controlled by digital information of NC machine tools. It is suitable for high-precision, complex parts and small and medium-sized batch production.

CNC machine tool is an efficient and flexible mechanical-electrical integration equipment which integrates computer technology, modern control technology, sensor detection technology, information processing technology, network communication technology, hydraulic pneumatic technology, optical and mechanical technology, and it is the basis of modern manufacturing technology.

1. Composition of NC Machine Tool and NC Machining Process

CNC machine tools refer to the machine tools that use digital information recorded in the media to control the machine tools through the CNC device, so that it can automatically implement the specified processing process.

1) Composition of CNC Machine Tools

NC machine tools automatically process workpieces according to pre-programmed processing procedures. CNC machine tools are usually composed of machine body, servo system, CNC device and control medium, as shown in Figure 2-61.

Figure 2-61 Composition of CNC Machine Tool

Control medium. Control medium, also known as information carrier, is an intermediate medium which conveys the operation intention of human to CNC machine tools. It contains all the information necessary to process a part. Commonly used control media are perforated tape, magnetic tape, disk and other carriers that can store instruction information. For the short NC processing program, the NC device can be input directly through the keyboard on the NC operation panel.

NC device. CNC device is the center of CNC machine tool. It receives the information from control medium, and converts it into pulse signal to control machine tool action.

Servo system. Servo system is a device which connects the moving parts of machine tool with CNC system, including servo drive mechanism and movable parts of machine tool. It is the executive part of CNC system of machine tool. It transforms the impulse signal from CNC device into the movement of machine tool parts, so that the worktable or tool holder can be positioned accurately or moved strictly according to the expected trajectory, and the parts meeting the requirements of the drawings can be machined.

Machine tool.  Machine tool is the mechanical part of NC machine tool. Besides the general parts such as main drive device, feed drive device, bed, worktable and auxiliary part, there are also special parts, such as tool storehouse, automatic tool changer and rotary worktable.

NC Machine Parts Processing Process

The NC machine tool parts processing process is that the operator first changes it into the content of manufacturing process according to the processing pattern. On the basis of familiarity with the processing technology, the processing program is compiled, and the human will is transformed into the acceptable information of CNC machine tools with the prescribed code and program format. Record information on control media (such as punched tape, tape or disk) to make it an instruction for controlling machine tools. After the input information is processed by the NC device, the command pulse is sent to the servo system of the coordinate axes of the machine tool to drive the corresponding moving parts of the machine tool, and other actions such as speed change, tool change and machine shutdown are controlled to automatically process the workpiece that meets the requirements of the drawings.

Classification of 2 NC Machine Tools

CNC machine tools can be classified according to process use, locus of motion, control mode and so on. This paper only introduces the classification according to process use. CNC machine tools are classified according to their processing characteristics or main processing procedures. They are mainly CNC lathes (including turning centers), CNC milling machines (including milling centers), CNC boring machines, CNC machining centers, CNC grinding machines (including grinding centers), CNC drilling machines (including drilling centers), CNC broaching machines, CNC planer, CNC cutting machine, CNC gear processing machine and CNC EDM machine (including EDM center, etc.). Figure 2-62 shows the appearance of CK50 NC lathe. Its processing range is the same as that of ordinary lathe. It mainly processes rotational parts such as shafts and discs. Figure 2-63 shows the appearance of XJK125 NC milling machine. It is especially suitable for the processing of complex parts. It can complete milling, drilling and boring.

Machining center (MC) is a kind of NC machine tool for multi-process machining of workpiece. It has a tool library and an automatic tool changer (ATC). After the workpiece is clamped once, under the control of the NC system, the machining center can automatically select and change the cutting tools according to different processes; automatically change the spindle speed, feed rate and the movement track of the tool relative to the workpiece and other auxiliary functions; sequentially complete the multi-process processing on several surfaces of the workpiece. Therefore, it reduces the time of workpiece clamping, measuring and machine adjustment, shortens the time of workpiece storage and handling, improves productivity and machine tool utilization, and it is an important development direction of CNC machine tools. Figure 2-64 shows the layout of JCS-018 machining center. Its shape is similar to that of vertical milling machine. There is a sliding seat 2 on the bed 1, and it moves horizontally (y axis direction). Workbench 3 moves longitudinally on the slide seat (x-axis direction). There are frame pillars 5 at the back of the machine tool. The spindle box 9 makes vertical lifting motion (z axis direction) on the column guide rail. The left and right parts of the column are the NC device 6, the left front part is equipped with the tool storehouse 7 and the automatic tool changing manipulator 8, and the left lower part is equipped with the lubrication device 4. There are 16 cutters in the tool library, which can complete all kinds of hole processing and milling. There are 16 cutters in the tool library, which can complete all kinds of hole processing and milling. The NC operation panel 10 is suspended in front of the operator's right for easy operation. The working state of the machine tool is displayed on the panel. Machining centers are usually divided into horizontal, vertical and universal machining centers according to the spatial position of the spindle during processing.

3 Programming

The so-called programming means that the process, process parameters, tool movement and direction and other auxiliary actions (tool changing, cooling, clamping, etc.) of parts are compiled into tables according to the sequence of movement and the instruction code and program format given by the NC machine tools used. This form is called "parts processing program sheet", or simply "procedure sheet". Then, all the contents of the program sheet are recorded on the control medium (such as perforated tape, tape, etc.), and then transmitted to the NC device to direct the NC machine tool processing. The whole process from the analysis of part drawings to the production of control media for NC machine tools is called programming.

Generally speaking, the steps of NC programming are: process design→numerical calculation→preparation of parts processing program sheet→preparation of control medium or program input→program verification and trial cutting.

1) Process design

On the basis of comprehensive analysis of part drawings, the clamping and positioning method, processing route (such as tool setting point, tool changing point, feed route), tool and cutting parameters (such as feed speed, spindle speed, cutting width and cutting depth) are determined.

2) numerical calculation

According to the part drawing and the determined processing route, the tool trajectory is calculated.

The general NC device has the functions of linear interpolation and circular interpolation. For processing simple parts consisting of arcs and straight lines, only the coordinate values of the intersection or tangent points (base points) of adjacent geometric elements on the contour of the part are calculated, and the starting and ending points of the straight line, the starting and ending points of the arc and the coordinate values of the center of the circle can be obtained. When the shape of parts is complex and the interpolation function of NC devices is inconsistent, more complex calculations are needed.

3) Writing Procedure Sheet for Parts Processing

According to the calculated coordinates of tool path, the determined cutting parameters and auxiliary actions, and the instruction codes and program formats prescribed by the NC system, a part processing program sheet is compiled.

4) Preparing control medium or program input

After the program sheet has been written, the operator or programmer must input the processing information into the NC device. According to the different input and output devices of the NC system, the program can be moved to some control medium first. Commonly used control media are U disk, disk, tape and so on.

Program Checking and Trial Cutting

The program must be checked and tested before it can be used formally. The method of checking is to input the contents of the control medium directly into the NC device to check whether the tool's trajectory is correct or not. On the CNC machine tool with CRT graphics display screen, the program checking and trial cutting can be carried out by simulating the cutting process of the workpiece; otherwise, the pen can replace the knife and coordinate paper can replace the workpiece, so that the machine tool can run and draw the processing trajectory.

These methods can only check whether the tool's motion path is correct or not, and can not check the machining accuracy. Therefore, the trial cutting of parts should also be carried out. If it is found that the accuracy of the parts can not meet the requirements through trial cutting, the program sheet and the control medium should be modified, and the error compensation method should be adopted until the qualified parts are processed.

4. Characteristics and Application of CNC Machine Tools

1) Characteristics of CNC Machine Tools

(1) High processing accuracy and stable processing quality. Because of the high manufacturing accuracy of CNC machine tool and the automatic processing according to the scheduled program, the artificial operation error is avoided, the consistency of the same batch of parts is good, and the product quality is stable.

High productivity. Because many parts can be processed in one clamping process, many intermediate processes (such as marking) are omitted. Generally, only the first piece inspection is needed, which greatly shortens the production preparation time, so the productivity is high.

(3) The high degree of automation reduces the intensity of labor and improves the working conditions. Except for the manual clamping of the blank, the whole processing process is automatically completed by the machine tool, which reduces the labor intensity of the operator and improves the working conditions.

(4)It has strong adaptability and good economic benefit. When the processing object is changed, the NC program can be redesigned without redesigning tools, fixtures and moulds. This greatly shortens the product development cycle and provides a shortcut for the development of new products. At the same time, the processing accuracy is high, the quality is stable, the waste rate is reduced, the production cost is reduced, and the productivity is high, so good economic benefits can be obtained.

(5) It is conducive to the modernization of production management. By using NC machine tools, the processing time of parts can be accurately calculated, and the management of inspection, fixture and semi-finished products can be effectively simplified, which is conducive to the modernization of production management. Because of the use of digital information, it is easy to form an integrated computer aided design and manufacturing system.

However, the cost of CNC machine tools is high, the technology is complex and the maintenance is difficult, which requires higher quality of management and operators.

Application of NC Machine Tool

CNC machine tools are widely used, especially suitable for processing parts with the following characteristics: multi-variety, small batch production parts; parts with complex structure and high precision requirements; parts with frequent modifications. CNC machine tools can save a lot of tooling costs, reduce the overall cost. It is expensive, and it does not allow scrap of key parts; urgent parts with the shortest production cycle are needed.

The essence of well drilling is to try to solve the problems of breaking rocks and discharging cuttings, protecting the well wall and deepening drilling. The well drilling rig should complete the operations of drilling water well, downhole tubes, well flushing, etc.

Through long-term production practice and scientific research, the well drilling methods can be divided into two kinds of drilling methods with industrial practical value: impact method and rotation method. From these two methods, a variety of rig models have been developed.

According to the classification of drilling methods, well drilling rigs can be divided into three types: percussion drilling rig, rotary drilling rig and mixed drilling rig.

According to the classification of circulation mode, it can be divided into four types: mud directional circulation drilling rig, mud reverse circulation drilling rig, conventional air drilling rig and air reverse circulation drilling rig.

According to the drilling depth, it can be divided into three types: shallow drilling rig, medium deep drilling rig and deep drilling rig.

According to the type of assembly, it can be divided into three types: truck mounted well drilling rig, trailer well drilling rig and bulk well drilling rig.

WHY AUTOMATION?

Automation can be defined as the technology by which a process or procedure is performed without human assistance.

In other words, automated manufacturing systems technology, is the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching on telephone networks, steering and stabilization of ships, aircraft and other applications and vehicles with minimal or reduced human intervention. Some processes have been completely automated.

Why is automation so widely used today?

1. Improving efficiency and control quality

Most of mechanical automation devices are able to automatically process and control the information, they are more sensitive, accurate and wider than manual in inspection area. The automatic control system makes sure that the execution of mechanism is conform to the design, which will be not affected by operators. Thus the production efficiency and quality can be ensured indirectly. For example, the CNC machine is mare stable and its production efficiency is 2 to 6 times of the ordinary machine; if the machine is equipped with flexible manufacturing system the utilization can make 1.2 to 3.2 times better, the number of machine tools can be reduced by 20%, the manpower can be reduced by 20%, the lead time can be reduced by 40% and the cost can be reduced by 20%. Besides, the mechanical automation devices can be adjusted by programming, so they are especially suitable for the production of multi-variety and small-batch products. In general, they are the good method for manufacturers to shorten the product development cycle and accelerate the upgrade.

2. Improving the production safety and reliability

Mechanical automation devices generally can automatically self-monitor, self-alarm, self-diagnosis, self-protect. When devices overload, overpressure, overcurrent, short circuit and meet other power failure during running, they will automatically start the protection program which will avoid accidents and improve the safety. Mechanical automation devices is consist of many electronic components, which reduce the movable components and wear parts, then they are more sensitivity and reliable, thus the failure rate is reduced and service life is longer.

3. Easy to adjust and maintain

The mechanical automation devices is adjustable by programming to meet various requirements and no need to change any components and parts. If the devices can memorize data, engineers can design several kinds of program and input in the devices, then the devices can change the execution base on different products and programs. Automated inspection and automatic monitoring of mechanical automation devices can automatically prevent failures in the working process and self-restore. Since the widespread adoption of program control and digital display in mechanical automation devices, the operation buttons and handle are reduced, so the operation is more convenient and simple. The motion of the mechanical automation devices is controlled by electronic control system, so they can recently complete all motions. The advanced mechanical automation devices can automatically optimize the operation base on the mathematical model of products and the change of the external parameters.

4. With compound function and widely applicable

Mechanical automation devices are compound and widely applicable, which get rid of the restriction of single function and technology of mechanical and electrical products. The automation level of them is improved greatly. The flexible and intelligent mechanical automation devices can automatically control, compensate, calibrate, adjust and protect themselves, so they can be applied to different occasions and different fields, to meet different requirements.

5. Improving working conditions

Mechanical automation devices are knowledge-intensive and technology-intensive. High level of automation can reduce labor intensity, prompt the factory automation, office automation, agricultural automation, transportation, automation, and even home automation.

Non-standard automation equipment industry as a whole presents an obvious upward trend, that is, non-standard automation equipment market has broad space, and even some traditional industries may become the most potential market. However, the number of non-standard enterprises in China is relatively large; the scale is small; the technology is backward; competition homogeneity is also obvious shortcomings, and in this field there is a gap of at least 10 years with developed countries. New non-standard automation equipment is often mechanics equipment, making full use of the latest achievements of information technology. Designers in some Chinese enterprises are not familiar with the products, dare not or will not choose them, which greatly limits the improvement of the level. Many core technologies are not really independent, and it is obviously difficult to reduce the cost of importing equipment. At present, high-end products, such as industrial robots and servo motors, are still mainly imported from abroad.

Although the non-standard automation equipment industry as a whole presents an obvious trend, the market space of non-standard automation equipment is vast, and even some traditional industries may become the biggest market potential. However, with the growth of similar enterprises in China, the proportion of non-standard automation products produced in China is steadily increasing.

Although batch processes are currently used, a number of more advanced techniques have been investigated in order to improve the process efficiency of organic acid fermentation. Promising every result must have been achieved using the tangential flow filtration in the continuous fermentation systems.

One of the main advantages of tangential flow filtration is that the higher biomass concentrations are possible because cells are continuously recycled back to the fermentor. A dense population of cells not only accelerates production of lactic acid but also minimizes contamination by foreign microorganisms. Thus high cell density continuous systems could increase the efficiency of lactic acid production. It can also be applied to nictric acid production.

Lactic acid fermentation broth on the main performance of the membrane fouling is

1. Gel polarization fouling of, membrane surface. Lactic acid fermentation broth by centrifuge coarse filters, except for a small amount of mycelium and solids, but also contains a lot of protein, sugar and easily carbonized material. During the membrane filtration process of lactic acid purification, these substances are easily deposited on the membrane surface and formed gel polarization fouling.

1. Membrane pore adsorption, crystallization pollution. Adding an excess of calcium carbonate is to adjust the system pH, in this way, the excess calcium carbonate is easily occurred crystallization within the hole and in the membrane surface. In the actual operation, the pipeline can easily generate a short temperature difference due to the solubility of calcium lactate which is very sensitive to temperature, so the calcium lactate is also vulnerable to precipitation surface or deposition within the membrane hole and in the membrane surface.

In order to remove impurities, ceramic membrane contamination mechanism in the process of lactic acid fermentation comes down to mycelium, protein, sugar and gel polarization pollution caused by carbonized material in the membrane surface of the and crystallization pollution of calcium carbonate - calcium lactate within the hole and membrane surface.

JIANGSU JIUWU HI-TECH CO. LTD.,founded in 1997, focus on producing ceramic membrane filters for many years. And JIUWU HI-TECH has become a leading company in the membrane separation industry. We sincerely invite and welcome people from all around the world to invest and create more values together.

APPLE JUICE

Apple juice in the press process will bring a lot of impurities in pulp, pectin, starch, plant fiber, microorganisms, bacteria, and other impurities. Thus, it's not easy to produce apple juice concentrate through traditional methods. Due to high sugar content in apple juice, microorganisms and bacteria are easy to breed which makes apple juice fermentation ferment and deteriorate.

High-temperature sterilization will result in product discoloration and loss of flavor. The traditional filtration methods (diatomaceous earth, framed filter) can not completely retain the impurities, can play a temporary clarification. Under the influence of time, temperature, charge,re-flocculation of dissolved impurities form visible matters, resulting in apple juice turbidity and precipitation.

Macromolecular impurities such as plant fiber, starch, bacteria and other impurities in apple juice are completely intercepted to realize the clarification and impurity removal of apple juice by crossflow microfiltration.

Cross-flow design is adopted to solve the problem of filter clogging and will greatly improve the efficiency of producing juice concentrate.

Advantages:

Filtrate is clear with high transmittance

Return muddy does not happen for a long time

No secondary precipitation produced

CIDER JUICE

Ceramic membrane filtration can also be used to produce cider juice, such as apple cider juice.

PEAR JUICE

In the fruit juice industry, fruit juice membrane technology is used mainly to clarify the juice by means of ceramic ultrafiltration and microfiltration and to concentrate it by means of nanofiltration and reverse osmosis.

We look at enzyme immobilization techniques to improve filtration performance and operation methods to quantify fouling.

Membrane fouling is a critical issue and inhibits the broader application of membranes in the fruit production industry. Pectin and its derivatives form a gel-like structure over the membrane surface, thereby reducing the permeate flux. In order to degrade pectin, the raw juice is usually subjected to an enzymatic treatment with pectinase, which hydrolyzes pectin and causes its protein complexes to flocculate. The resulting juice has reduced viscosity and much lower pectin content, which is advantageous in the subsequent filtration processes.

MUSHROOM JUICE

Mushroom is a common edible fungus in life, rich in protein, 18 kinds of amino acids, vitamins and calcium, iron and other minerals.

However, mushroom's respiration is exuberant after picking. The mushroom quickly becomes browning and changing taste at room temperature and is only for short-term storage. Dried mushrooms are easy to preserve, but the nutritional value is reduced. If you want to store for a long time, you need a higher condition, even in these special circumstances, it is easy to be infected by microorganisms and spoilage, which greatly affects its nutritional value.

After the mushroom is processed into mushroom juice, it not only reduces the storage cost, but also is convenient to eat, and keeps the original nutrients of mushroom. This is the latest type of fruit and vegetable juice drink.

LUCERNE JUICE

With the development of science and technology, the research on lucerne has been deeply studied, and the nutrition and health function of lucerne have been highly evaluated. Due to rich crude protein cellulose, vitamins, minerals, and complete amino acid composition, it is a worth developing juice in the beverage field.

VEGETABLE JUICE

Membrane separation processes are widely used in the production of beverage materials and the treatment of water for drinking. The technology can be applied to deacidify, debitter, clarify, concentrate and filter vegetable juices.  It plays an important role in the improvement of product quality, the increase in output and the decrease in production cost.

Vegetable juices are used due to convenience. The juices are rich in various minerals, vitamins, and other nutrients. To process the juices and their clarification and/or concentration is required. The membranes are being used for these purposes. These processes are preferred over others because of high efficiency and low temperature.

Membranes and their characteristics have been proved for knowing suitability of membranes for vegetable juices. Membrane separation is low-temperature process in which the organoleptic quality of the juice is almost retained.

Ultrafiltration (UF) is a variety of membrane filtration in which forces, such as pressure or concentration gradients, cause separation through the semi-permeable membrane. High molecular weight suspended solids and solutes remain in the so-called retentate while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). The pore size of the ultrafiltration membrane is in the range of 0.01μm ~ 0.05μm, suitable for the separation, concentration and purification of macromolecules and small molecules.

Application of Ceramic ultrafiltration Membrane 

UF technology can be used to remove particulates and macromolecules from raw water to produce potable water. It has been used to replace the existing secondary (coagulation, flocculation, sedimentation) and tertiary filtration (sand filtration and chlorination) systems used in water treatment plants or as stand-alone systems in isolated areas with a growing population.

When treating water containing highly suspended solids, primary (screening, flotation and filtration) and some secondary treatments are often used as a pretreatment stage to incorporate ultrafiltration into the process.

When water recovery is simple, very little processing is often required. However, when more in-depth processing is required, industry standard procedures include the use of UF membrane technology, which means removing the physical solids from the water by passing them through a semipermeable membrane. With ultrafiltration, the solids are primarily captured by the filter and discarded.

Circulating water can also be used in a variety of industrial applications including water supply to boilers or cooling towers, pH control, cleaning equipment, hard beds and vehicles, fire fighting, rinsing or process water for manufacturing industrial lines, toilet flushing, dust control, construction activities Mix with concrete.

Ultrafiltration is often used to pre-treat surface water, seawater and bioprocessed municipal water upstream of reverse osmosis plants.

Industries that consume large amounts of water or discharge highly toxic wastewater may use ultrafiltration to recover water.

These include chemicals, steel, plastics and resins, paper and pulp, pharmaceutical and food and beverage industries, including soft drinks and canned foods, and electricity, water and wastewater treatment plants.

Ultrafiltration is used to recycle flow or add value to later products and more. In many cases ultrafiltration (UF) is used for prefiltration in reverse-osmosis plants to protect the reverse-osmosis process. Ultrafiltration is an effective means of reducing the silt density index of water and removing particulates that can foul reverse osmosis membranes.

Features of Ultrafiltration Membrane

Ultrafiltration processes are preferred over traditional treatment methods for the following reasons:

• No chemicals required (aside from cleaning)
• Constant product quality regardless of feed quality
• Compact plant size
• Capable of exceeding regulatory standards of water quality, achieving 90-100% pathogen removal.

RO membrane technology is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water.

In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter.

The reverse osmosis membrane technology can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes) but should allow smaller components of the solution (such as solvent molecules) to pass freely.

Advantages of reverse osmosis

1. Removes nonionic impurities and dissoved solids (i.e.organics,silica,bacteria)
2. Reduction of hazardous chemical storage and handling associated with ion exchange
3. Reductes loading on ion exchange systems:

• Extends run lengths
• Extends resin life
• Reductes operating costs

Application range of reverse osmosis

• • Desalination
  • Dehydration
  • Concentration
  • Remove COD/BOD

Nanofiltration (NF) or nanofiltration membrane technology is a relatively recent membrane filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors such as natural organic matter and synthetic organic matter.

The membranes are key to the performance of NF systems. They are produced in spiral wound, tubular, and hollow fiber formats, from a range of materials, including cellulose derivatives and synthetic polymer.

NF membranes have pore sizes from 1-10 nanometers, smaller than that used in microfiltration and ultrafiltration, but just larger than that in reverse osmosis.

Application range of NF Membrane Technology 

• Desalination & purification
• Dehydrated, concentrated
• Decolor
• Solvent recovery

The ceramic microfiltration membrane element ( MF membrane) is made from alumina and zirconia which is an asymmetric membrane structure with multi-channel tubular shape. The pore is on the channel. Driven by operation pressure, the liquid is running in the membrane. The part less than pore size is permeation, the part lager than pore size is concentrated liquid, so as to achieve the separation, concentration and purification purposes.

JIUWU ceramic membrane manufacturer produces the ceramic microfiltration membranes with the pore size 200nm, 500nm, 1200nm and so on.  JIUWU microfiltration system made by high-quality MF membranes element will meet the requirements for your special applications. 

OVER VIEW OF MICROFILTRATION CERAMIC MEMBRANE ELEMENT

Ceramic microfiltration membrane is a type of physical filter element where a contaminated fluid is passed through a special pore-sized membrane to separate microorganisms and suspended particles from process liquid. The most common application of ceramic microfiltration membrane is clarification, or removal of suspended solids to produce a clear liquid. It is commonly used in conjunction with various other separation processes such as ultrafiltration and reverse osmosis membrane technology to provide a product stream which is free of undesired contaminants. Examples include clarification of whole cell broths; purification processes in which macromolecules must be separated from other large molecules, enzymes or cell debris; clarification of dextrose and highly colored fruit juices, wine and beer, during which fruit juice membrane and beer membrane filtration will be used; whey de-fatting and casein removal. Ceramic microfiltration membrane systems operate at relatively low pressures and come in a variety of configurations. They are characterized by pore size, ranging from 0.05 micron to 1 micron.

JIUWU company offers a large choice of ceramic microfiltration membranes with different geometries and cut-offs to meet your process requirements in viscosity, molecule size, impurity profile, purity and yield target, etc. as well as cleaning and sanitization procedures.

MF ceramic membrane usually serves as a pre-treatment for other separation processes such as ultrafiltration, and a post-treatment for granular media filtration. Learn more micro filtration technology here!
