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.

The difference between wet expansion and dry expansion is that the raw materials are prepared in advance before expansion, and the temperature is increased by steam or water. The so-called conditioning refers to the hot and wet effect of steam on pet food raw materials, so that the starch in the raw materials is pre gelatinized, the protein is denatured and the raw materials are softened, which is conducive to improving the expansion granulation effect and expansion quality of dog food.

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.

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.
