Twin screw extruder is composed of two high-torque screws which are meshing with each other and rotating in the same direction. Since the design range of screw and cylinder is wide, the outline and process functions of various screws can be set according to the process requirements. Therefore, the twin screw extruder can ensure transportation, compression, mixing, cooking, shearing, heating, cooling, pumping and forming with high strength of flexibility. The purpose of extrusion processing is to transform the viscosity polymer medium through physical and chemical changes by precise control of processing conditions, and produce high quality structured products. The new generation of twin screw extruder adopts the latest modular design concept, realizing the multi-purpose of the extrusion system and perfectly connecting with the upstream and downstream supporting equipment. The intelligent control system can realize the flexibility and visualization of adjusting different production process parameters according to different production process requirements. It can be widely used in many fields of the food industry and is an ideal choice for processing breakfast cereal, snack food, food raw materials, modified starch, pet food and so on.
