Pellet Feed Extruder Machine

A floating fish feed extruder is a machine that processes raw materials into fish feed pellets that float on water for extended periods. Floating pellets are ideal because they help fish farmers monitor the fish’s feeding behavior and reduce feed waste.

✅ Key Features

• Produces Floating Pellets: Pellets can float for 12-24 hours.

• Adjustable Size: Pellet size can be adjusted from 0.5 mm to 15 mm.

• Temperature & Pressure Control: Ensures proper cooking and extrusion.

• Single-screw or Twin-screw Types: Twin-screw models offer higher capacity and versatility.

• Electric or Diesel Operated: Based on the model.

⚙️ Working Principle

1. Mixing: Raw materials like fish meal, corn, soybean, vitamins, etc., are mixed.

2. Extrusion: The mixture is fed into the extruder, where it is cooked by high temperature and pressure.

3. Shaping: The screw forces the material through a die, shaping it into pellets.

4. Cutting: Rotating knives cut the pellets to desired sizes.

5. Drying & Cooling: Pellets are dried to remove moisture and cooled to harden.

6. Flavoring (optional): Oils or attractants can be sprayed on the cooled pellets.
