🧠 Key Takeaways

• Producing 1.5mm floating fish feed requires precise control of moisture, temperature, and formulation
• Fine grinding and uniform mixing are critical for small pellet formation
• High starch content improves expansion and floating performance
• Proper die size and cutter adjustment ensure uniform pellet diameter
• Stable extrusion conditions prevent blockage and ensure consistent output

🟡  1. Why 1.5mm Floating Feed Is Difficult to Produce?

Small pellets behave differently during extrusion.

❗ Main Challenges:

• Easy to break during cutting
• Lower expansion compared to larger pellets
• Higher risk of blockage
• Requires finer raw materials

👉 Without proper control, pellets may sink or become powdery.

 

---

🟡 2. Raw Material Requirements

✔ Particle Size

Must be ≤0.5 mm

Fine grinding is essential

✔ Moisture Content

20–25% before extrusion

✔ Recommended Formula

Ingredient	Function
Corn flour	Starch for expansion
Soybean meal	Protein source
Fish meal	Nutrition
Wheat flour	Binding

 

👉 Starch content is key to floating ability.

🟡  3. Step-by-Step Production Process of floating fish feed extruder machine

🔧 Step 1: Fine Grinding

Raw materials are ground into ultra-fine powder.

👉 Ensures smooth extrusion and prevents blockage.

 

🔧 Step 2: Mixing

Materials are mixed uniformly.

👉 Uneven mixing leads to unstable pellet quality.

 

🔧 Step 3: Conditioning

Water or steam is added to adjust moisture.

👉 Proper moisture improves expansion.

 

🔧 Step 4: Extrusion

Inside the floating fish feed pellet maker machine:

• High temperature cooks the feed
• Pressure builds up
• Starch gelatinizes

👉 This creates the floating structure.

 

🔧 Step 5: Die & Cutting Adjustment

Use 1.5mm die holes

Adjust cutter speed carefully

👉 Critical for pellet size consistency.

 

🔧 Step 6: Drying

• Reduce moisture to ≤10%
• Improve storage life

 

🔧 Step 7: Cooling

• Stabilizes pellet shape
• Prevents breakage

🟡  4. Key Parameters for 1.5mm Feed Production

Parameter	Recommended Range
Particle size	≤0.5 mm
Moisture	20–25%
Temperature	120–160°C
Screw speed	Medium-high
Starch content	≥20%

👉 These parameters directly affect floating rate and pellet strength.

🟡 5. How to Improve Floating Performance?

✔ Increase Starch Content

More starch = better expansion

 

✔ Control Temperature

Higher temperature improves puffing

 

✔ Maintain Proper Moisture

Too dry → poor expansion
Too wet → soft pellets
