The twin-screw food expanding machine has two pairs of screws that mesh with each other and rotate in the same direction, which together serve the functions of conveying, friction pressing and heating, inputting materials by the principle of positive displacement, forcibly conveying, and rarely forming pressure backflow. Therefore, the problem of this aspect in the single-screw extrusion type extruder is better solved, and the powerful conveying machine combines various functions such as compression, mixing, mixing, shearing, melting, sterilization, puffing, molding, etc. Completed in a short period of time. The transformation of the mold can change the shape and size of the product infinitely. The twin-screw extruder can produce a wide variety of foods, which can produce snack foods, breakfast cereals, sandwich puffed foods, instant rice noodles, soups, Bread slices, organized vegetable protein, candy, flavoring components, pet food, fish and shrimp feed, etc., and can develop countless new foods.
Throughout the development needs of the industry, food expansion machinery can be considered from the following four aspects:
1. Applicability of scale. The equipment used by China's puffed food processing enterprises is mainly divided into three sizes: large, medium and small.
2. Safety applicability. Safety applicability is mechanical safety, production safety and food safety in the processing of puffed food.
3. Complete applicability. Complete applicability is an important link to ensure continuous operation, balanced production, processing performance and product quality.
4, hygienic applicability. It is the mechanical design and manufacturing process of the puffed food.
It mainly includes structural materials such as product contact surface and non-product contact surface, surface structure, cleanability, durability, and inspectability;
Main features of food puffing machinery: Food puffing machinery is the most popular main machine in the market. Its production of puffed food (pet food, fish feed, etc.) has a wide range of applications. Among them, 70 is the outer diameter diameter of the screw. The machine is supplied by the feeding system. , extrusion system, rotary cutting system, heating system, transmission system, control system. Using advanced screw extrusion technology, using high temperature and high pressure to mature and puffing materials, one-time completion. The mainframe adopts frequency conversion speed regulation to ensure production. The stability of the process. The product color, variety, appearance, natural and realistic, fine texture, wide use of raw materials.
