wet Type floating fish feed pellet processing machine test
May 12, 2026
Introduction
Our factory recently completed a successful testing process for a wet Type floating fish feed making machine before shipment. During the factory trial, the machine continuously produced floating fish feed pellets with stable puffing performance, smooth pellet surfaces, and uniform pellet sizes.
The customer mainly evaluated steam conditioning performance, floating feed quality, production stability, and compatibility with local aquaculture feed formulas.
Compared with dry type fish feed machines, wet type floating fish feed processing systems provide better feed gelatinization, improved pellet stability, and more efficient continuous production for commercial aquaculture feed manufacturing.
What Was Tested During The wet Type Floating fish feed extruder machine Trial
During the testing process, engineers carefully monitored the complete floating fish feed production system.
Main Testing Items
- Floating performance of fish feed pellets
- Steam conditioning effect
- Pellet expansion stability
- Continuous production performance
- Feed moisture control
- Extrusion pressure stability
- Pellet appearance quality
The machine operated continuously during the test and maintained stable extrusion without material blockage.
Raw Materials Used During The Factory Test
The customer selected several commonly used aquaculture feed ingredients for practical testing.
Tested Feed Ingredients
- Corn flour
- Soybean meal
- Fish meal
- Wheat flour
- Rice bran
- Vitamin premix
These materials were mixed evenly before entering the conditioner and extrusion system.
Why Raw Material Testing Is Important
Different feed formulas directly affect:
- Floating performance
- Pellet density
- Expansion ratio
- Water stability
- Feed digestibility
Testing local raw materials before shipment helps customers improve production efficiency after installation.
What Is The Function Of The Conditioner In A wet Type floating fish food making machine
The conditioner is one of the key components in a wet type fish feed production system.
Main Functions Of The Conditioner
Steam Pre-Cooking
Steam heats and softens raw materials before extrusion.
Improved Feed Gelatinization
Better starch cooking improves pellet floating ability.
Stable Material Moisture
Conditioning improves moisture consistency before extrusion.
Reduced Screw Wear
Steam-softened materials reduce friction inside the extrusion chamber.
The testing process showed that conditioned materials produced smoother and more stable floating fish feed pellets.
Finished Floating Fish Feed Pellet Performance
The finished pellets produced during the machine trial showed stable quality suitable for commercial aquaculture feed production.
Pellet Features
Long Floating Time
Pellets floated continuously without sinking quickly.
Uniform Pellet Diameter
The extrusion system produced consistent pellet sizes.
Smooth Pellet Surface
Stable conditioning improved pellet appearance quality.
Good Water Stability
Pellets maintained structure in water and reduced feed waste.
Reduced Pellet Powder
Stable extrusion pressure reduced pellet breakage after drying.
These pellet characteristics are important for improving feed conversion efficiency in fish farming.
Main Advantages Of The wet Type fish feed pellet extruder machine
Stable Continuous Production
Suitable for medium and large-scale aquaculture feed factories.
Better Pellet Quality

FAQ
Q1: What is the advantage of a wet Type fish feed making machine?
Wet type machines use steam conditioning to improve pellet quality, feed digestibility, and floating performance.
Q2: Can the wet Type fish feed pellet machine produce both floating and sinking fish feed?
Yes. Different formulas and machine settings 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 level is usually around 20%-25% depending on the feed formula.
Q5: Why is steam conditioning important in fish feed production?
Steam conditioning improves starch gelatinization, pellet compactness, and feed expansion quality.
Conclusion
The successful wet Type floating fish feed pellet mill test demonstrated stable continuous production, reliable steam conditioning performance, and high-quality floating pellet output.
For commercial aquaculture feed manufacturers, wet type fish feed processing systems provide an efficient solution for producing floating aquatic feed with improved pellet quality, stable production capacity, and flexible feed formula compatibility.
