The twin-screw extruder in food processing is suitable for the production of various extruded foods, including snack food, textured vegetable protein, nutritional powder, biodegradable packaging materials, starch gelatinization, rice assembling (fortified rice, nutritional rice analog, instant rice), pet feed, aquatic feed, etc.

Twin screw food extruder has greater friction performance than single screw extruder, so they have better puffing capabilities and are suitable for high-humidity extrusion processes. Suitable for various low-viscosity or high-viscosity raw materials.

Its characteristics are as follows:
The whole machine is a modular structure, which performs feeding, extrusion, heating, cooling, forming, cutting, water injection and other processes respectively. Operation and maintenance are simple.

Each module and detail has been strictly designed, with the greatest investment in the use of materials, carrying meticulous craftmanship in processing accuracy. Therefore, the interconnection and cooperation among all parts are tight and scientific, and the twin screw extruder overall operation is stable, accurate, high in efficiency and low in energy consumption.
