twin screw extruder
The twin-screw extruder is used for processing equipment that mainly expands products directly. Normally, starch raw materials such as rice, corn, flour, etc., are extruded by two screws in the barrel of the equipment, and expanded by the die outlet. And get the product.
Through different raw materials and formulas, various puffed foods commonly found in the market can be produced. Through different screws and barrels, special products that are not expanded and semi-expanded can also be produced.
The twin-screw extruder has two pairs of screws that mesh with each other and rotate in the same direction, which together play the role of conveying, frictional extrusion and heating, relying on the principle of positive displacement to input materials for forced conveying, and seldom form pressure Reflux, so as to better solve this problem on the single-screw extruder.
The extruder integrates multiple functions such as compression, mixing, mixing, shearing, melting, sterilization, expansion, and molding, and completes them in a very short time. The change of the mold can change the shape and size of the product infinitely.
The twin-screw extruder can produce a wide variety of foods, including snack foods, breakfast cereals, sandwich puffed foods, instant rice noodles, soups, bread slices, textured vegetable protein, candy, seasoning components, pet food, fish Shrimp feed, etc., and countless new types of food can be developed.
