Introduction

Recently, our factory completed a successful testing process for a 200-300kg/h floating fish food pellet making machine before shipment to the customer. During the machine trial, engineers tested pellet floating performance, production stability, extrusion pressure, and raw material adaptability to ensure stable operation after installation.

The customer mainly focused on floating feed quality, pellet size consistency, machine running stability, and actual production capacity.

This floating fish feed pellet extruder machine is suitable for fish farms, aquaculture cooperatives, and small-to-medium aquatic feed manufacturing businesses.

What Was Tested During The floating fish feed pellet mill Trial

During the factory testing process, the engineering team inspected the complete fish feed extrusion workflow.

Main Testing Items

• Floating ability of fish feed pellets
• Pellet puffing stability
• Production output consistency
• Machine operating condition
• Pellet surface quality
• Feed moisture control
• Continuous extrusion performance

The machine operated continuously during the trial and produced stable floating feed pellets without blockage.

Raw Materials Used During The floating fish food extruder machine Testing

The customer selected several common aquaculture feed ingredients for practical testing.

Tested Feed Ingredients

• Corn flour
• Soybean meal
• Fish meal
• Wheat bran
• Rice bran
• Vitamin premix

These materials were mixed evenly before entering the floating fish feed extruder machine.

Why Raw Material Compatibility Testing Matters

Different feed formulas directly affect:

• Pellet floating performance
• Feed expansion ratio
• Pellet hardness
• Water stability
• Feed digestibility

Testing local feed ingredients before shipment helps customers reduce future production risks.

Q2: Can the floating fish feed extruder machine produce sinking fish feed?

Yes. By adjusting formulas and extrusion settings, the machine can produce floating or sinking pellets.

---

Q3: Why are floating fish feed pellets sinking after production?

Low starch content or insufficient extrusion pressure may reduce pellet buoyancy.

---

Q4: What is the recommended moisture content before extrusion?

The recommended moisture content is generally around 20%-25%.

---

Q5: Why does the extrusion screw wear quickly?

Continuous overload production or abrasive raw materials may increase screw wear.
