Feed puffing processing technology is not only suitable for large-scale breeding enterprises, but also for professional straw feed production and processing plants. It helps to improve straw utilization efficiency, reduce breeding costs, and improve the growth performance and breeding benefits of herbivorous animals.
Fish have a high demand for feed protein during growth, so protein content has become a key indicator for evaluating the quality of fish feed. The application of puffed feed processing technology in the field of aquaculture has been quite extensive.

Puffed feed can be customized according to the characteristics of different fish. Its feed pellets are of excellent quality and have little impact on water pollution. At the same time, it has high nutritional value and convenient feeding methods. Therefore, the nationwide distribution of feeds such as sturgeon, rainbow trout, shrimp, marine fish, and tilapia fully demonstrates the superiority and broad development prospects of puffed feed in aquaculture.
Feed processing and modulation is a key link in the production of puffed feed. Through this process, the original properties and morphology of feed raw materials are changed, thereby producing feed with high nutritional value and good palatability.
During the modulation process, various methods such as chemical, physical or biological methods can be used according to the different characteristics of the raw materials. In addition, optimizing the modulation device is also an important means to improve the quality of extruded feed.
The twin-screw extruder is the core equipment in the production of extruded feed. During the extrusion and extrusion process, the screw sleeve and screw extrude and shear the feed raw materials and extrude the die hole under high temperature and high pressure. This process enables the feed raw materials to expand rapidly in an instant, thus meeting the needs of breeding.
