200-250kg/h Fish Feed Machine Customer Factory Test for Floating Fish Feed Production
May 12, 2026
Introduction
Before purchasing a fish feed production machine, most buyers focus on one question:
Can the machine produce stable floating fish feed with local raw materials?
In this factory test, our customer tested a 200-250kg/h Dry Type floating fish feed making machine using practical aquaculture feed formulas. The test included raw material mixing, extrusion, floating performance, pellet shaping, moisture control, and final feed appearance evaluation.
Why Customers Request A Factory Test Before Buying A Dry Type fish feed pellet processing machine?
Factory testing is one of the most important steps before confirming a fish feed production line order. It helps customers reduce investment risks and verify whether the machine matches local production requirements.
During this test, the customer mainly focused on:
- Floating performance of fish feed pellets
- Stability of pellet size and shape
- Compatibility with local raw materials
- Machine running stability
- Capacity output between 200-250kg/h
- Power consumption and labor requirement
- Moisture control after extrusion
A real machine test provides more reliable results than only checking photos or catalogs. It also helps customers understand the complete fish feed production process before installation.
Raw Materials Used During The Dry Type floating fish feed pellet making machine Test
The customer used common aquaculture feed ingredients available in local markets.
Main Raw Materials
- Corn flour
- Soybean meal
- Wheat bran
- Fish meal
- Rice bran
- Vitamin premix
- Oil additives
These materials were crushed and mixed evenly before entering the fish feed extruder machine.
Why Raw Material Testing Matters
Different raw materials affect:
- Feed floating time
- Pellet expansion rate
- Water stability
- Pellet hardness
- Fish digestion performance
Testing local formulas inside the factory allows customers to optimize feed recipes before mass production.

Fish Feed Pellet Performance During Factory Testing
The customer paid special attention to final pellet quality because pellet performance directly affects fish growth and feed conversion ratio.
Tested Pellet Features
Good Floating Ability
The pellets floated on water for a long time without sinking quickly.
Uniform Pellet Size
The machine produced consistent pellet diameters suitable for different fish species.
Smooth Pellet Surface
Stable extrusion pressure improved pellet appearance and reduced powder.
Strong Water Stability
Pellets maintained shape in water, reducing feed waste.
Adjustable Feed Density
By changing the formula and machine parameters, sinking or floating feed could both be produced.

What Problems Were Checked During The Machine Test
Professional buyers usually focus on production stability rather than only machine price.
During the testing process, the customer carefully checked:
- Whether pellets break after drying
- Whether the machine blocks during extrusion
- Whether motor operation is stable
- Whether feed moisture is too high
- Whether pellet floating time is sufficient
- Whether the machine is easy to clean and maintain
This practical testing process helps customers avoid installation and production problems later.
Common Fish Feed Production Problems And Solutions
Why Are Fish Feed Pellets Not Floating?
Possible Causes
- Low starch content
- Extruder temperature too low
- Incorrect moisture ratio
- Screw wear after long-term use
Solutions
- Increase corn or starch materials
- Adjust heating temperature
- Control moisture between 20-25%
- Replace worn screw parts
Why Does The Dry Type fish feed production equipment Block Frequently?
Possible Causes
- Raw material particle size too large
- Excessive moisture
- Uneven feeding speed
Solutions
- Use a hammer mill for fine grinding
- Reduce water addition
- Maintain stable feeding quantity
Why Are Feed Pellets Breaking After Drying?
Possible Causes
- Drying temperature too high
- Formula lacks binder materials
- Pellet moisture removed too quickly
Solutions
- Lower dryer temperature gradually
- Add wheat flour or starch binder
- Control drying time properly
Why Is The Output Lower Than 200kg/h?
Possible Causes
- Incorrect screw configuration
- Insufficient motor power
- Raw material formula imbalance
Solutions
- Optimize screw compression ratio
- Check electrical stability
- Adjust feed formulation

How To Improve Floating Fish Feed Quality
To produce high-quality floating fish feed consistently, operators should focus on several critical points.
Important Production Tips
- Grind raw materials finely
- Maintain stable moisture content
- Use balanced protein formulas
- Regularly inspect extruder screws
- Control extrusion temperature carefully
- Dry pellets gradually after extrusion
Stable process control helps reduce feed waste and improve fish growth performance.
FAQ
Q1: What is the best moisture content for floating fish feed production?
The recommended moisture content before extrusion is usually 20%-25%. Excessive moisture may cause poor pellet expansion and unstable floating performance.
Q2: Why does the dry type floating fish feed pellet mill produce uneven pellet sizes?
Uneven pellet size is usually caused by unstable feeding speed, worn die holes, or inconsistent raw material grinding fineness.
Q3: How can I reduce powder in finished fish feed pellets?
Use finer raw material grinding, proper starch ratios, and controlled drying temperature to reduce pellet breakage and powder generation.
Q4: Why does the fish feed machine motor become overloaded?
Motor overload may occur because of excessive feeding quantity, high raw material moisture, or blockage inside the extrusion chamber.
Q5: How often should the dry-type fish feed extruder screw be replaced?
Screw replacement depends on production hours and raw material abrasiveness. Regular inspection is recommended after long-term continuous operation.
Q6: Why are fish feed pellets sinking too quickly?
Low puffing pressure, insufficient starch, or incorrect temperature settings can reduce pellet buoyancy and cause sinking.
Conclusion
The 200-250kg/h dry type floating fish food extruder machine factory test allowed the customer to verify real production performance before purchasing. From raw material adaptability to floating pellet quality, practical testing helps reduce operational risks and improve future feed production efficiency.
For fish farms and small feed manufacturers, conducting a factory test before shipment is an effective way to confirm machine quality, optimize feed formulas, and ensure stable floating fish feed production.
