Do you know how such delicious puffed food tastes? People who know puffed food know that puffed food is a special food made of some grains and other materials through special processing methods. The reason why puffed food is delicious is inseparable from its later seasoning.

Puffing technology refers to that the material containing certain moisture is sent into the extruder. Driven by the screw rod and screw, the material moves forward to form an axial movement. The mechanical friction between the material and the screw, the material and the barrel and the interior of the material. The material is strongly extruded, stirred and sheared, so that the material is further refined and homogenized. Then, the pressure and temperature inside the cavity continue to increase and rise, and the material is under high temperature, high pressure Under the action of high shear force, the material components have complex physical and chemical changes. Finally, the paste material is ejected from the die hole, resulting in an instant pressure difference, and the material is expanded to form an expanded product with loose structure, porous and crisp.

Textured soybean protein is a food prepared from soybean protein isolate and soybean defatted soybean powder. Defatted soybean, 70% protein soybean powder and separated soybean protein are mixed with water and food additives, pretreated by crushing, stirring, heating and direct steam, and then mixed, extruded, sheared and shaped by extrusion extruder. At the same time, the raw materials are sterilized and Protein organization and starch α Chemical treatment such as chemical treatment, enzyme passivation, melting, high temperature treatment, cooling, drying and other heat treatment. Due to the conversion of globulin in protein isolate and soybean defatted soybean powder into silk protein and fibrin, the protein content is more than 50%. The dried food can still have enough bite (bite strength and bite) similar to meat after adjusting water or rehydration.

- single screw extruder: suitable for processing all kinds of raw materials and ordinary livestock and poultry compound feed - twin screw extruder: the final product requires good molding and beautiful appearance, compound feed (aquatic products, pet food) with uniform maturity and adjustable density, and raw materials with high added value（ ɑ Starch, tissue protein, etc It should be noted that the above division is not absolute. For example, we recommend using twin-screw to produce aquatic feed, but at present, many enterprises use single screw to produce aquatic feed. Many articles have introduced their application in aquatic products

It is precisely because of the many advantages of twin-screw compared with single screw in the production of aquatic feed, we suggest that twin-screw should be preferred in the production of this kind of products

Single screw extruder is suitable for all kinds of fried puffed food, extruded food, nutritious rice, etc. The barrel adopts two-way temperature control of heating and water cooling, and the screw can be cooled with water. The temperature is stable and the product quality is high.

Difference between single screw extruder and twin screw extruder

A lot of differnet shapes die moulds for you too choose to enhance the products variety

Fully automatic,easy operation and save human work,high efficiency.Multy function can produce differnt type product
