The method of reducing feed pulverization rate

Pulverization is an unavoidable problem in pellet feed, but as long as the production process is reasonable, equipment operation is standardized, reasonable raw materials and formulas are selected, and management is strengthened, the pulverization rate of pellet feed can be completely reduced.

1. Raw materials with high starch content can be tempered at higher temperature and humidity, which can promote starch gelatinization, lubricate during granulation, and increase granulation output. low rate.

2. The natural protein has large capacity, heat denaturation, increased plasticity and cohesiveness, less fine powder produced during crushing, which is beneficial to increase the yield of granulation.

3. Appropriate addition of oil will soften the particles, reduce the resistance of passing through the ring die, reduce the degree of wear of the ring die, and increase the granulation output, but the amount added should not exceed 3%. Adding molasses can not only improve the nutritional value, but also act as a binder to improve the wear resistance and hardness of the feed.

4. For raw materials with extremely poor granulation performance, some cementing agents such as starch, lignin, gelatin, etc. can be added in an appropriate amount, which can improve the cohesion of granulation, but will increase the cost.
