Testing of 180-500kg/h wet Type Floating fish feed extruder machine with conditioner

Introduction

For commercial aquaculture feed production, stable pellet quality and continuous machine operation are more important than simply increasing output capacity.

During this factory test, the customer evaluated a 180-500kg/h wet Type floating fish feed making machine equipped with a steam conditioner. The testing process focused on floating pellet quality, steam conditioning performance, feed expansion effect, moisture stability, and machine running efficiency.

Compared with dry type fish feed extruders, wet type extruders with conditioners provide more stable gelatinization, smoother pellet surfaces, and better floating performance for commercial fish feed manufacturing.

This article explains the complete testing process, machine configuration, pellet quality results, and common production problems customers usually care about before purchasing a floating fish feed production line.

Why Customers Choose wet Type floating fish food making machines?

wet Type floating fish feed pellet processing machines are widely used in medium and large aquaculture feed factories because they provide better feed cooking performance and higher pellet quality.

Main Advantages Of Wet Type Fish Feed Extruders

Better Feed Gelatinization

Steam and heat improve starch cooking, helping pellets float longer in water.

More Stable Pellet Quality

Conditioned materials enter the extrusion chamber more evenly, reducing pellet cracks and powder.

Higher Production Efficiency

Wet type machines support continuous large-scale feed production.

Lower Screw Wear

Steam-softened materials reduce internal friction inside the extruder.

Improved Fish Feed Digestibility

Better cooked feed improves nutrient absorption for fish farming.

These advantages make wet type floating fish feed machines suitable for commercial aquaculture businesses.

What Is The Function Of The Conditioner In A Fish Feed Extruder Machine?

The conditioner is one of the most important parts of a wet type fish feed extrusion system.

Main Functions Of The Conditioner

• Pre-cooks raw materials before extrusion

• Mixes steam evenly with feed powder

• Improves starch gelatinization

• Stabilizes material moisture

• Enhances feed expansion effect

• Reduces extrusion pressure fluctuation

During testing, the customer observed that conditioned materials produced smoother and more uniform floating pellets compared with unconditioned materials.

Raw Materials Used During The Extruder Testing Process

The customer tested several common aquaculture feed formulas during the factory trial.

Tested Feed Ingredients

• Corn flour

• Soybean meal

• Fish meal

• Wheat flour

• Rice bran

• Vitamin premix

• Fish oil

These raw materials were crushed and mixed before entering the conditioner and extrusion system.

Why Raw Material Compatibility Testing Matters

Different feed ingredients directly affect:

• Floating performance

• Pellet density

• Expansion ratio

• Feed hardness

• Water stability

• Production capacity

Testing local feed formulas before shipment helps customers reduce production risks after installation.

 180-500kg/h Wet Type Floating Fish Feed Production Process

The factory test demonstrated the complete fish feed manufacturing workflow.

Standard Production Steps

Raw Material Crushing

Large particles are ground into fine powder using a hammer mill.

Feed Mixing

Different ingredients are mixed uniformly.

Steam Conditioning

Steam enters the conditioner to pre-cook feed materials.

Extrusion Pelletizing

The wet type fish feed extruder shapes and expands the pellets.

Drying Process

The dryer removes excess moisture from fresh pellets.

Flavoring And Oil Spraying

Oil and additives improve feed palatability and nutrition.

Cooling And Packaging

Pellets are cooled before storage and packaging.

This process is commonly used for floating fish feed production in commercial aquaculture industries.

Fish Feed Pellet Performance During Factory Testing

The customer carefully inspected the final pellet quality during machine operation.

Tested Pellet Characteristics

Stable Floating Ability

Pellets floated continuously for a long time without breaking apart.

Smooth Pellet Surface

Steam conditioning improved pellet appearance and compactness.

Uniform Pellet Diameter

The machine produced stable pellet sizes suitable for different fish species.

Reduced Powder Content

Conditioned extrusion reduced pellet breakage after drying.

Good Water Stability

Pellets maintained shape in water, reducing feed waste.

These testing results are critical for fish farms that require high feed conversion efficiency.
