Description Twin screw extruder is developed on the basis of single screw extruder. The emergence of twin-screw extruders has replaced the traditional single-screw extruders with low efficiency and cumbersome operation. Raw materials such as rice, corn, soybeans, and wheat in daily life are extruded through a twin-screw extruder, and then formed into triangles, circles, hexagons, and cartoon shapes by rolling or stamping. Various flavors can later be produced by frying, baking or seasoning. Application Twin screw extruder is well used for extrusion production of pet food, aquatic feed industries, and soya industries and for massive productions with low starch content and high percentage of protein and fat, to realize a wide variety of sizes and shapes of final products, etc.
