اخبار شرکت 180-200kg per Hour Dry Type Single Screw Floating Fish Feed Pellet Extruder Machine Working Video

The 180-200kg/h Dry Type single screw floating fish feed extruder machine is a cost-effective solution for small-to-medium-scale aquaculture. Designed for regions with limited infrastructure, it produces high-quality floating feed (Tilapia, Catfish) without an external boiler. With a floating rate of over 95% and flexible power options (Electric/Diesel), this machine reduces feed costs by 30-50% for local farmers.

1. Technical Specifications & Performance

Understanding the technical "why" behind the Dry Type Single-Screw floating fish feed pellet maker machine is crucial for professional buyers.

2. How It Works: The Science of Dry Extrusion

Expert Insight: Why do the pellets float?

The Dry Type single screw floating fish feed making machine operates on the principle of Thermo-mechanical Energy. Unlike wet-type extruders that use external steam, this dry-type machine generates heat through mechanical friction between the high-speed screw and the barrel.

1. Compression: Raw materials are pressurized inside the hardened barrel.

2. Gelatinization: Temperatures reach 120°C–150°C, cooking the starch and modifying proteins.

3. Expansion: As the material exits the die into atmospheric pressure, the moisture flashes into steam, creating a porous, lightweight structure that ensures the feed floats.

3. Optimized Feed Formulations for African Local Ingredients

To maximize ROI, farmers should use locally available raw materials. Our engineering team recommends the following ratios:

A. Tilapia Floating Feed (Growth Stage)

• Maize/Corn Meal (30%): Essential for starch and expansion.

• Soybean Meal (35%): Primary protein source.

• Rice Bran/Wheat Bran (20%): Fiber and energy.

• Fish Meal (10%): High-quality animal protein.

• Vitamins/Minerals (5%): Growth and immunity.

B. Catfish Floating Feed (High Protein)

• Fish Meal/Blood Meal (25%): High protein for carnivorous needs.

• Groundnut Cake (20%): Affordable local protein.

• Soybean Meal (25%):

• Cassava Flour (20%): High starch content to ensure buoyancy in deep ponds.

• Premix (10%):

Expert Tip: Always ensure your raw material moisture is between 15% and 25%. If it's too dry, the screw may jam; if it's too wet, the pellets won't expand (float).

4. Adaptation for African Environmental Conditions

This Dry Type single screw floating fish food maker machine is specifically engineered for tropical and subtropical climates (Nigeria, Uganda, Kenya, etc.).

• Power Solution: We offer 415V/50Hz 3-Phase customization for Nigeria and Kenya. For rural areas, the Diesel Engine version is the most popular choice to bypass grid instability.

• Dust & Heat Resistance: The motor is built with a high-grade insulation (IP54/IP55) to handle high ambient temperatures and dusty milling environments.

• Corrosion Protection: The screw and barrel are made of 38CrMoAl alloy steel, nitrogen-treated to resist wear from abrasive local ingredients like rice husks.

5. Troubleshooting & Maintenance

Real-world experience shows that 90% of Dry Type Single-Screw fish food maker machine downtime is preventable.

• Uneven Pellet Size: Check the cutter blade sharpness and distance from the die plate.

• Feed Sinking: This usually means the temperature wasn't high enough. Increase the friction (tighten the pressure ring) or increase the starch (maize/cassava) content.

• Weekly Maintenance:

  • Grease the main bearings every 40 hours of operation.

  • Check belt tension to prevent power loss.

  • Clean the die holes immediately after stopping the machine to prevent "caking."

6. Why Invest in Local Production? 

In countries like Ghana and Zambia, imported feed costs have risen by 40% due to shipping and currency fluctuations.

• Cost Reduction: Producing your own feed can save  200-400 per ton

• Freshness: Locally produced feed maintains higher vitamin potency than feed stored in shipping containers for months.

• Customization: You can adjust the protein level based on the specific growth stage of your fish.

FAQ: 

Q1: Can I produce sinking shrimp feed with this Dry Type single screw floating fish feed pellet making machine?
A: Yes. By adjusting the formula (reducing starch/expansion) and removing the pressure ring, you can produce sinking feed.

Q2: How long do the pellets float?
A: With a proper formulation (20%+ starch), pellets will float for over 12-24 hours without disintegrating.

Q3: Is it difficult to change the pellet size?
A: No. You simply swap the die plate at the end of the extruder. We provide sizes from 1mm to 8mm.

Q4: Do I need a dryer after extrusion?
A: Yes. Even though it is a "dry type" extruder, the pellets exit with some heat and moisture. Air-drying or a simple belt dryer is recommended for long-term storage.
