When the raw materials of the feed extruder are extruded by the large, medium and small fish feed pellet machines, the temperature is moderate, which can well maintain the trace elements in the raw materials. The pellets have a natural cooked aroma and are very palatable. Fish and shrimp like to eat them. The fish feed pellet mechanical mold plate can be used on both sides, and the mold plate can be used for 800-1000 hours, which is economical and affordable. The fish and shrimp feed pellet machine can reasonably feed pellet feed according to the type and size of the fish, and according to the needs of each growth stage. In the process of using the fish feed pellet machine, the preventive drugs and raw materials are stirred together and then pelletized. This can prevent and treat fish diseases, thereby improving the survival rate of aquatic products.

1. Forming is smooth.
2. Float in water for more than 12 hours without sinking.
3. No pollution to water sources.
4. Sterilization reduces fish diseases.

                     The extruder has a screw and a screw sleeve, which have the functions of mixing and kneading. After the raw material enters the expansion chamber, the material is squeezed, rubbed, sheared, etc. between the screw sleeves. The internal pressure continues to increase, with a limit value of 4Mpa, and the temperature continues to rise, with the limit value reaching 140 degrees Celsius. Within 3-7 seconds, the temperature and pressure increase sharply, and the organizational structure of the material changes, further gelatinizing the starch, denaturing the protein, destroying the crude fiber, and killing harmful bacteria such as salmonella.
