What are the applications of Pellet binder in fish and shrimp feed
Compared with livestock and poultry feed, fish and shrimp feed has special requirements for processing and pelleting. It is generally required that fish feed pellets have a water resistance of ≥0.5 hours in water, and shrimp feed pellets have a water resistance of ≥2 hours in order to reduce loss and improve feed utilization. To solve the problem of water resistance of aquatic pellet feed, two methods are generally adopted: one is to increase raw materials with more starch content, such as secondary flour and wheat flour, to produce a certain cohesive force after gelatinization to improve the water resistance of pellets; the other is to increase the water resistance of pellets . Add a special Pellet binder (or granulation aid) to the feed to make the granules have a certain degree of water resistance through the unique cohesive force. The first method takes a long time, and it will cause greater damage to certain heat-sensitive substances in feed materials, such as vit...
