Working Principle of Floating Fish Feed Pellet Making Machine
With the growing popularity of AOWIN floating fish feed pellet making machine, we mainly introduce its working principle here. If you need a detailed introduction to the sinking fish feed pellet making machine, please contact us directly.
Brief Introduction
The floating fish feed pellet making machine creates a high-temperature and high-pressure environment through mechanical energy friction and steam. When the material passes through the extrusion die holes, the sudden pressure drop causes the material to expand rapidly, forming a porous structure. In the fish feed production line, it is also equipped with crushing, mixing, drying, cooling and packaging processes to ensure high-quality floating fish feed.
Conditioning | Mixed powdered raw materials first enter the conditioner of the floating fish feed pellet making machine. High-pressure steam is injected to make the materials absorb moisture evenly, realizing starch gelatinization and protein denaturation, which enhances plasticity for subsequent extrusion forming. |
Extrusion | The conditioned materials are transported to the extrusion chamber of the floating fish feed pellet making machine. Through screw conveying and pressure extrusion, combined with high temperature, the materials are formed into floating pellets. The friction between materials and equipment ensures stable extrusion and meets the requirements of aquaculture feed. |
Forming | The fully matured materials are extruded through the die of the floating fish feed pellet making machine. The sudden pressure drop makes the materials expand rapidly, forming porous floating pellets that can float on water, which is the core principle of floating feed production. |
