Common problems and solutions in the production of floating fish feed pellet

With the benign development needs of low pollution, low waste, high efficiency and high conversion of the global fishery feed, the extruded floating fish food feed pellet is gradually becoming a new type of aquatic feed that is gradually accepted and promoted by the majority of farmers. In recent years, the output of aquafeed has grown rapidly, especially the demand for shrimp and some precious special aquafeeds has increased sharply.

At present, the processing technology and production characteristics of each feed production equipment manufacturer are different, and even the product quality of the same variety produced by the same manufacturer in different batches may fluctuate greatly.

What are the defects of extruded feed pellet during processing?
After years of practical experience in production and continuous communication with customers, we have summarized the following twelve common problems and corresponding solutions for customers’ reference.

The size and length of the feed pellets are uneven;
Too many pores in the feed pellet;
Feed pellets deformation;
The hardness of the feed pellet is not enough;
Poor water resistance and poor viscoelasticity in feed pellets;
The feed pellet incision is irregular and oblique;
Low feed pellet expansion;
The feed pellets do not float;
