Protein materials, starch, vitamins, and additives are mixed uniformly.
Step 3: Extrusion Puffing
The floating fish feed extruder cooks and shapes the feed pellets under high temperature and pressure.
Step 4: Pellet Drying
Fresh pellets are dried to reduce moisture and extend storage life.
Step 5: Oil Spraying And Flavoring
Oil and nutritional additives improve feed palatability.
Step 6: Cooling And Packaging
Pellets are cooled and packaged for transportation or storage.
Stable process control helps maintain consistent feed quality during long-term production.
