Introduction

Our factory recently completed the testing process for an 800kg/h commercial use floating fish feed pellet mill before shipment. During the factory trial, the machine continuously produced floating fish feed pellets with stable expansion performance, uniform pellet size, and smooth surface quality.

The customer mainly focused on production capacity, floating pellet stability, machine operating performance, and compatibility with local aquaculture feed formulas.

This commercial floating fish feed production system is suitable for medium and large aquaculture feed factories, fish farming cooperatives, and commercial aquatic feed processing businesses.

What Was Tested During The floating fish food pellet making machine Trial

During the machine test, our engineers carefully inspected the overall production stability of the floating fish feed extrusion system.

Main Testing Items

• Floating performance of fish feed pellets
• Production output stability
• Pellet expansion effect
• Continuous extrusion performance
• Feed moisture control
• Motor running condition
• Pellet surface smoothness

The machine operated continuously during testing and maintained stable production without extrusion blockage.

Raw Materials Used During The Factory Test

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

Tested Feed Ingredients

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

The raw materials were crushed and mixed evenly before entering the floating fish feed extruder machine.

Why Raw Material Compatibility Testing Matters

Different feed formulas directly affect:

• Floating performance
• Pellet hardness
• Expansion ratio
• Water stability
• Feed conversion efficiency

Testing local feed ingredients before shipment helps customers optimize future production.

Finished Floating Fish Feed Pellet Performance

The finished pellets produced during the factory trial showed stable physical quality suitable for commercial aquaculture feed production.

Pellet Features

Stable Floating Ability

Pellets floated on water for a long time without dissolving quickly.

Uniform Pellet Size

The extrusion system produced consistent pellet diameters during continuous operation.

Smooth Pellet Surface

Stable extrusion pressure improved pellet appearance and reduced powder.

Good Water Stability

Pellets maintained structure in water and reduced feed waste.

Adjustable Pellet Sizes

Different die molds can produce pellets for different fish growth stages.

These pellet features are important for improving feeding efficiency and reducing aquaculture production costs.

Common Problems And Solutions During Floating Fish Feed Production

Why Are Fish Feed Pellets Not Floating Properly?

Possible Causes

• Insufficient starch content
• Low extrusion temperature
• Incorrect moisture ratio

Solutions

• Increase corn or starch materials
• Adjust extrusion temperature
• Control feed moisture carefully

Why Does The floating fish feed processing machine Become Blocked?

Possible Causes

• Raw material particles too large
• Excessive moisture
• Unstable feeding speed

Solutions

• Improve crushing fineness
• Reduce water addition
• Maintain stable feeding quantity

Why Are Fish Feed Pellets Breaking After Drying?

Possible Causes

• Excessive drying temperature
• Poor formula balance
• Rapid moisture removal

Solutions

• Lower drying temperature gradually
• Improve starch ratio
• Extend drying time properly

Why Is Production Output Lower Than 800kg/h?

Possible Causes

• Screw wear
• Motor instability
• Improper raw material formula

Solutions

• Inspect screw condition regularly
• Check electrical system
• Optimize feed ingredient ratio

FAQ

Q1: What fish species can this floating fish feed pellet maker machine produce feed for?

The machine can produce feed for tilapia, catfish, carp, shrimp, and many other aquatic species.

Q2: Can the machine produce both floating and sinking fish feed?

Yes. Different formulas and extrusion parameters can produce floating or sinking pellets.

Q3: Why are floating 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 floating fish feed extruder machine screw wear quickly?

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

Conclusion

The successful testing of the 800kg/h commercial use floating fish feed pellet extruder machine demonstrated stable production performance, reliable extrusion capability, and good floating pellet quality.

For commercial aquaculture feed manufacturers and medium-scale fish farming businesses, this floating fish feed production system provides an efficient solution for producing high-quality aquatic feed with stable continuous operation and flexible feed formulas.
