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 of it is one of the key technologies to ensure the quality and safety of feed products.

Inspection and maintenance safety operation procedures

Twin screw extruder is suitable for a wide range of raw materials, many product shapes and flexible configuration. Choosing different models and configurations can produce different products.

After years of practical experience in equipment production. It is considered that the following defects generally appear in the processing of expanded materials: 1. Uneven particle size and length; 2. There are many pores in particles; 3 particle deformation; 4. The hardness of particles is not enough; 5. The particle has poor water resistance and viscoelasticity; 6. The particle incision is irregular and oblique; 7. The expansion of particles is not high; 8. Particles are submerged; 9 particles are big at one end and small at the other; 10. The particles form a concave shape in the double cut plane; 11 particles with tail; 12 particle surface peeling. In this paper, some problems often occurred in the processing of expanded materials are summarized, and the corresponding solutions are put forward.

Automatic large pet aquatic feed production line

Select the production equipment of aquatic feed, First of all, we should understand the many characteristics of aquatic feed

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.
