Single-Screw Aquatic Feed Extruder Advantages

✅ Versatile Feed Production
Capable of producing various types of feeds including: Floating fish feed, Sinking aquatic feed, Pet food, Full-fat soybean meal

✅ High Output Capacity
When producing Φ3.0mm tilapia feed, the machine delivers an output of 5.0–5.5 tons/hour, making it suitable for commercial operations.

✅ Advanced Material & Durability

Uses innovative wear-resistant materials, extending the lifespan of vulnerable components by 2–3 times. Screw service life reaches 8000–10,000 tons of feed.

✅ High-Precision Extruder Chamber

Constructed with reinforced strength to prevent deformation of the jacket or loosening of the wear-resistant bushing. Supports both heating and cooling operations for precise control.

✅ Modular Screw & Barrel Design

A flexible combination of chamber and single-screw allows easy adjustment and structural change. Convenient for switching between different feed types and raw materials.

✅ Floating Time Control

Extrusion degree can be adjusted to regulate floating time in water, ideal for different species’ feeding behavior.

✅ Energy Efficient Operation

Optimized design helps reduce power consumption and lowers the overall cost of feed production.
