Operational Principles of Floating Fish Feed Extruder

This smart floating fish feed extruder machine regulates internal temperature and pressure metrics precisely to expand the material naturally upon discharge for creating highly buoyant feed pellets.

Free Consultation

Steam Preheating Stage

The raw ingredients mix with high-temperature steam inside the stainless steel conditioner before entering the main compression chamber. This hot vapor softens the material completely and initiates starch gelatinization across the mixture. This step regulates ingredient moisture levels properly to ensure the finished pellets remain firm and durable after extrusion.

High Pressure Cooking

The preheated material enters the fish extruder machine where the rotating screw pushes it forward through intense physical friction. The internal chamber generates temperatures between 120 and 140 degrees Celsius alongside high pressure instantly. This environment cooks the raw materials thoroughly to create a highly uniform, dense paste structure.

Depressurization Expansion Shaping

From the discharge mold holes of the floating fish feed extruder machine, the cooked paste exits into an environment where an abrupt drop in pressure instantly vaporizes the internal moisture.

This expansion creates thousands of uniform microscopic pores inside the shaped feed pellets. This spongy internal matrix reduces pellet density and enables the finished feed to float on water for hours.
