Twin Screw Puffed Extruder Machine-manufacture,factory,supplier from China

When using a twin-screw extruder, the twin-screw extruder needs to install the device correctly, so that it can save energy and time during production.The twin-screw extruder is fully automated from batching, extrusion, puffing, molding, core sandwiching, cutting, spraying to finished products at one time. The production line has the characteristics of many optional models, flexible equipment configuration, wide range of raw materials, many types of products, and simple operation.

When operating a twin-screw extruder, it should be maintained on time. The maintenance process is carried out after the twin-screw extruder runs continuously for 2500-5000h and shuts down. The screw is extracted to inspect, measure and identify the wear condition of the most critical components, replace the components that have reached the specified wear limit as soon as possible, and repair the damaged components . The maintenance standard of the reducer of the twin-screw extruder is the same as that of the ordinary standard reducer.

The advantages of our twin screw extruder:1. Double screw snack extruder adopts side forced feeding technology, which increases the integrity of the material and greatly increases the output. The position and shape of the feed port also have a great influence on the feed efficiency. Under the same parameters, the feed area increases and the output increases. For the same inlet area, rectangular section has greater feed efficiency than circular section. The use of side twin screw feed is also based on such a consideration.2. Twin screw extruder has strong self-cleaning ability.

Working Principle of Twin Screw ExtrusionAfter a certain amount of pulverization, the material with a certain water content is fed into the extruder cavity, so that the material will undergo mixing, shearing, A series of complex continuous processes such as melting, curing and sterilization. Because there is a certain air pressure difference inside and outside the barrel, the moment the material is extruded, the external pressure it is subjected to is reduced to normal pressure, so that the material is instantly puffed.

The fiber-drawing protein of twin-screw extruder takes low-temperature soybean meal, soybean protein isolate and wheat gluten as main raw materials. In the twin-screw extruder, the processes of extrusion, forced transportation, crushing and kneading, mixing and homogenizing, shearing and extrusion are completed. At the same time, the processing process of high temperature and high pressure and sterilization is continued to modify protein molecules and form a new layered fiber structure. Produce high-strength, high-toughness, texture and taste similar to meat.

Twin screw extruder is developed on the basis of single screw extruder. Two screws are placed side by side in the barrel of the twin screw extruder. According to the meshing degree of the two screws can be divided into mutual meshing type and non-meshing type. According to the rotation direction of the two screw shafts, it can be divided into reverse rotation type and co-rotation type.(1) meshing twin screw: Because the meshing gap of the meshing screw is very small, the material has the ability of forced conveying, not easy to produce backflow, leakage phenomenon.

Series double screw extruder introduction:1, mainly by the feeding system, extrusion system, rotary cutting system, heating system, lubrication system, control system.2, extruder feeding system, main drive system, rotary cutting system all adopt frequency control, strong power, smooth operation, power saving.3, automatic lubrication, forced cooling, to ensure the safe operation of the extruder and prolong the life.4, screw alloy material, through special processing, high strength, wear resistance, increase the service life.5, according to different products, with different structure and length

Keeping the twin-screw extruder clean can produce better products. Keeping it clean can also reduce the failure rate and ensure continuous production. The basic elements of twin-screw extrusion equipment maintenance - inspection and cleaning.The inner wall of the cooling water pipe attached to the twin-screw extrusion equipment is easy to scale, and the outside is easy to rust and corrode. Careful inspection should be done during maintenance. Excessive scale will block the pipeline, and the cooling effect will not be achieved. If the rust is serious, it is easy to leak water.

Twin screw extruder to keep clean can produce better products, keep clean can also reduce the occurrence of failure rate, ensure the continuous production, twin screw extrusion equipment maintenance basic elements - inspection, cleaning.The inner wall of cooling water pipe attached to twin screw extrusion equipment is easy to scale, and the outside is easy to rust and corrosion. The maintenance should be carefully checked.

Q: As an important screw on the extruder, what is the difference between the twin-screw extruder and the single-screw extruder?A: Like a general single-screw extruder, it consists of a transmission system, an extrusion system and a heating and cooling system.
