The new twin screw artificial rice extruder developed by our company can produce all kinds of nutritious rice, fortified rice, instant rice and other artificial rice. The equipment adopts PLC touch screen control, the operation is more intuitive and simple; New gear box, including oil cooling, oil filtering system, effectively prolong the service life;

The moisture content of pellet feed is a very important quality index, which directly affects the quality of pellet feed and the economic benefits of feed enterprises. Effective control is one of the key technologies to ensure the quality and safety of feed products.

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.

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.
