Biodegradable plastics refer to a kind of plastic that is degraded by natural microorganisms such as bacteria, fungi and algae. The ideal biodegradable plastic is a kind of polymer material with excellent performance, can be completely decomposed by environmental microorganisms after waste, and eventually become an integral part of the carbon cycle in nature by inorganization. Biodegradable plastics are mainly made from natural polymers (such as starch, cellulose, chitin) or agricultural by-products through microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, aliphatic polyesters, polylactic acid, starch/polyvinyl alcohol and so on.

The main target markets of biodegradable plastics are plastic packaging film, agricultural film, disposable plastic bags and disposable plastic tableware. Compared with traditional plastic packaging materials, the cost of new degradable materials is slightly higher. However, with the increasing awareness of environmental protection, people are willing to use new biodegradable materials with a slightly higher price to protect the environment. Enhanced awareness of environmental protection has brought tremendous opportunities for the development of biodegradable new materials industry. Recycled plastics refer to a kind of waste plastics that can be recycled and reused through a certain recycling process.

Waste plastics are mainly plastic film, plastic silk and knitted goods, foam plastics, plastic packaging boxes and containers, daily plastic products, plastic bags and agricultural films. After manual screening and classification, waste plastics are subjected to such processes as crushing, granulation and modification.

All kinds of transparent and opaque plastic particles are transformed, then classified according to the phase, and finally become reusable recycled materials. Biodegradable materials and recycled materials can be classified as environmentally friendly materials. With the increasing awareness of environmental protection, the industry of environmentally friendly materials has brought tremendous opportunities for development. Nanjing KY Chemical Machinery Co., Ltd. can provide a complete set of recycled plastic extruder solutions from raw material transportation to mixing granulation according to the characteristics of environmental protection materials and according to the needs of customers.

Screw type oil press and hydraulic press are two main types of oil press in the market at present. These two kinds of oil press have their characteristics, and they should be selected according to their characteristics as reference. Helix is relatively old, driven by motors through belts, chains or gears, with low efficiency and single control, which is not suitable for complex applications. Hydraulic pressure is more advanced, efficient, small, easy to control, large output, more widely used, slightly expensive.

In the way of oil pressing, screw type oil press produces high temperature through screw extrusion and extracts oil from oil. The hydraulic press uses the liquid as a medium to pressurize oil, to extract oil. In terms of oil quality, the screw press will destroy the nutrients in the oil because of the high temperature when it works, and it needs to be treated by oil cooling. A hydraulic press is a physical way to extract oil, and the quality of the oil extracted is better. When sesame, almond, peanut, and other materials are used, the hydraulic press should be used. In terms of oil yield, screw type oil press has a high oil yield, while the hydraulic press has a relatively low oil yield.

Working Principle of Automatic Screw Feeding Systems

Pour the material into the feeding box and start the switch. The material is continuously lifted from the bottom of the feeding box to the outlet through screw. There is a time setting in the automatic screw feeding systems. Feeding time can be set according to each feeding quantity. Spring feeder adopts screw conveying principle.

The material is rotated from the storage tank to the plastic extruder with a wire spring until the filling signal is sent out by the level device. It stops eating. After a period of time, it can restart the reciprocating cycle. According to the user's requirements, time relay can be used to control the downtime and realize automation.

The automatic screw feeding system is mainly used for the feeding of various plastic powder, granules and powder mixtures, and is used in conjunction with extruders and injection moulding machines. It can also be used to transport flour, talc powder and other powder. The utility model has the advantages of convenient operation, stable performance, large conveying capacity and long service life.

Application of Automatic Screw Feeding Systems

The machine can be used in a wide range of applications, such as powder feeding, plastic granules, powder mixtures, crushers, and powder feeding in pharmaceutical and chemical production processes. It consumes less energy. Compared with traditional vacuum feeder and spring dust feeder, its energy consumption is only about one third of them.

The screw feeder is a necessary auxiliary machine for plastic, food and chemical processing machinery. It can automatically convey powder or granular sheet materials to hopper directly. It is a special equipment for adjusting mixer and so on. Contact materials are made of stainless steel. The raw materials in the process of transportation are completely free from pollution, and no foreign bodies are brought in. It can make the production process completely closed and automated.

Mobile screw feeder is easy to install and movable. If more than one mixer uses the same material, one screw feeder can supply it at the same time, so as to avoid the trouble of manual feeding and make the feeding work safer, more time-saving and more labor-saving.
