The large-scale wet twin-screw pet aquatic feed production line

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.

Aquaculture has always been an important part of national agriculture. It depends on mountains and rivers. For the majority of farmers close to the water area, aquaculture fish and shrimp is a realistic and feasible method and way for them to obtain economic benefits.

Extrusion technology is a commonly used technology in modern feed processing. After the feed is processed by extruding technology, it can make starch gelatinization and degradation, protein denaturation, reduce anti-nutritional factors, increase palatability and many other advantages in the feed; but there are also unfavorable factors such as generating indigestible substances, destroying vitamins, and increasing costs.
