Twin-screw food puffing machinery with two intermeshing and the same direction of rotation of a pair of screws, which together play a role in conveying, friction extrusion and heating, relying on the principle of positive displacement of the input material, forcible conveying, and seldom form a pressure reflux, which is a better solution to the single-screw extrusion puffing machine on the problem in this regard, strong conveying. Puffing machine set compression, mixing, mixing, shearing, melting, sterilization, puffing, molding and other functions in one, in a very short period of time all completed. Mold changes can be unlimited changes in the shape and size of the product, twin-screw puffing machine can be a wide variety of production line food, can produce casual snack foods, breakfast cereals, sandwich puffed food, instant rice noodles, soups, slices of bread, organized vegetable protein, candy, seasoning components, pet food, fish and shrimp feed, etc., and can be developed into countless kinds of new food.

　　Throughout the industry development needs, food puffing machinery can be roughly from the following four aspects to consider:

　　1, scale applicability. China's puffed food processing enterprises to use the equipment is mainly divided into large, medium and small scale.

　　2, safety applicability. Safety applicability is puffed food processing machinery safety, production safety and food safety.

　　3, a set of applicability. Suitability is to ensure continuous operation, balanced production, processing performance and product quality is an important part.

　　4, health applicability. Expanded food machinery design, manufacturing process of the mechanical structure of the health cattle requirements.

　　Mainly includes product contact surface and non-product contact surface of the structure of the material, surface structure, cleanability, durability, checkability and other health requirements.

　　Food puffing machinery main features: food puffing machinery for the market now the hottest host, its production of puffed food (pet food, fish feed, etc.) has a wide range of applications. Which 70 for the screw outer diameter diameter size. The machine consists of feeding system, extrusion system, rotary cutting system, heating system, transmission system, control system. It adopts advanced screw extruding and puffing technology, using high temperature and high pressure to cook and puff the material, one-time completion. The host adopts frequency conversion speed control to ensure the stability of the production process. Product color, variety, beautiful appearance, natural and realistic, delicate texture, raw materials are widely used.
