Cheaper Price Dry-Type Single-Screw floating fish feed pellet maker machine shrimp feed pellet machine for Small Farms

Our dry-type single-screw floating fish food pellet making machine is a high-performance industrial solution designed for large-scale commercial aquafeed production plants. Integrated with a pre-conditioner (steam injection), it delivers superior gelatinization (up to 95%), higher capacity, and premium floating pellets for intensive aquaculture (tilapia, catfish, bass, shrimp). Ideal for 3–10 TPH production lines, it balances efficiency, versatility, and low operational costs for large farms and feed manufacturers.

Working Principle
The single screw floating fish food maker machine adds steam pre-conditioning to optimize extrusion:
1. Pre-Conditioning: Raw materials enter a steam conditioner where saturated steam (160–180°C) is injected, heating materials to 80–90°C and adjusting moisture to 18–25% for 2–5 minutes.
2. Extrusion & Thermo-Mechanical Processing: Conditioned materials move to the screw-barrel system; screw shear + residual steam heat raise temperature to 120–180°C and pressure to 5–10 MPa.
3. Gelatinization & Sterilization: Extended thermal treatment achieves 90–95% starch gelatinization, fully sanitizes feed, and improves nutrient availability.
4. Extrusion & Pellet Formation: High-temperature mash exits the die, expands via pressure release, and is cut into uniform floating pellets.
5. Post-Processing: Pellets go to dryer/cooler to reach 10–12% moisture for long-term storage.

Structure Composition
1. Steam Conditioner: Jacket cylinder with mixing blades + steam injection system (pre-heats/moisturizes materials)
2. Extrusion Main Body: Heavy-duty single screw (38CrMoAl alloy, nitrided), segmented barrel with cooling/heating zones
3. Power Transmission: High-power motor (90–220kW) + heavy-duty gearbox (high torque, low noise)
4. Temperature Control System: 4–6 zone PID control (steam/electric heating + water cooling)
5. Die & Cutter System: Multi-hole stainless steel die (0.6–20 mm aperture) + servo-controlled cutter
6. Control Panel: Industrial PLC touchscreen (auto-adjusts parameters, fault diagnosis)
7. Safety System: Emergency stop, overload protection, temperature alarm

Main Advantages & Features
✅ Superior Pellet Quality: 90–95% starch gelatinization; 48+ hour water stability; uniform porous structure (maximizes floating time).

✅ Wide Formula Adaptability: Handles high-protein (≥40%), high-oil (≥10%) formulas; produces floating/sinking shrimp/fish feed.

✅ Automated Operation: PLC control + parameter memory; 1-person operation; reduces labor by 50%.

✅ Durable & Stable: Imported bearings/seals; continuous 24-hour operation; screw life ≥10,000 tons.

Product Parameters

Product Applications

• Large Commercial Aquafeed Plants: Production for tilapia, catfish, bass, trout farms (100+ ton annual output)
• Intensive Marine/Freshwater Farms: High-protein floating feed for high-value species
• Shrimp & Crab Feed: Slow-sinking feed (adjustable expansion) with 24+ hour water stability
• Multi-Species Feed Production: Switches between fish, shrimp, and pet feed via die/formula changes
  

Raw Material Requirements
Raw Materials: Cereal grains, soybean meal, fish meal, shrimp meal, blood meal, oil, vitamins, minerals

• Particle Size: 80–120 mesh (ultra-fine grinding for high-quality pellets)
• Moisture: 10–14% (pre-conditioning adjusts to 18–25%)
• Fat Content: ≤18% (excess fat reduces expansion; use post-spray for higher fat)
  
• Raw Material Mixture: Uniformly mixed (ribbon mixer recommended)
