1.What Is the 3 mm wet Type fish feed production equipment Test?

The 3 mm wet type small fish feed pellet maker machine test is a factory testing process where a wet type fish feed extruder is operated using real aquatic feed formulas to verify 3 mm pellet forming accuracy, floating performance, steam conditioning stability, and continuous extrusion efficiency before delivery or commercial production use.

2. Why 3 mm Pellet Testing Is Important?

3 mm floating fish feed pellets are commonly used for:

• juvenile tilapia
• medium-growth fish stages
• intensive pond farming systems

Pellet size consistency directly affects:

• fish feeding efficiency
• feed conversion ratio (FCR)
• floating stability in water
• feeding competition behavior

3. What Is a wet Type floating fish feed pellet mill?

A wet Type fish feed extruder machine uses external steam conditioning before extrusion. Steam and moisture soften raw materials before entering the extrusion chamber.

This process improves:

• starch gelatinization
• pellet expansion
• floating stability
• feed digestibility

4. Step-by-Step 3 mm Pellet Testing Process

Step 1: Raw Material Preparation Test

Materials used during testing may include:

corn flour

soybean meal

fish meal

wheat flour

vitamin premix

Technicians check:

raw material fineness

moisture ratio

formula consistency

Step 2: Steam Conditioning Test

This is the key wet type feature.

Engineers monitor:

steam injection balance

material softening condition

temperature stability before extrusion

Step 3: Extrusion Pressure Stability Test

Inside the extruder:

materials are compressed under pressure

temperature increases gradually

expansion begins before discharge

Observed during testing:

stable extrusion pressure

smooth material flow

no blockage inside barrel

Step 4: 3 mm Pellet Forming Test

This is the most important testing stage.

Technicians inspect:

exact 3 mm pellet diameter

pellet roundness

surface smoothness

cutting precision

Step 5: Floating Test in Water

Pellets are tested immediately after production.

Observed results:

floating duration

pellet integrity in water

resistance to fast disintegration

Step 6: Continuous Running Stability Test

Machine operates continuously under load.

Checked:

steam system balance

extrusion continuity

motor temperature stability

pellet consistency over time

5. Why Wet Type Extrusion Performs Better for 3 mm Floating Feed

Better Pellet Expansion

Steam conditioning improves internal pellet structure.

Higher Floating Stability

More uniform expansion helps pellets float longer.

Improved Digestibility

Better starch gelatinization supports fish nutrient absorption.

More Stable Continuous Production

Wet type systems maintain smoother extrusion conditions.

6. Real Factory Test Data

7. Common Problems Checked During Testing

Problem: uneven 3 mm pellet size

Possible cause:

unstable extrusion pressure

inconsistent cutting speed

Problem: pellets sink too quickly

Possible cause:

insufficient starch gelatinization

poor steam conditioning

Problem: pellet cracking

Possible cause:

incorrect moisture balance

unstable drying conditions

8. Suitable Applications

This machine is suitable for:

commercial fish feed factories

tilapia feed production

catfish feed manufacturing

floating aquatic feed processing

medium and large aquaculture farms
