The SJPS Series Single-Screw Extruder is the specialized solution for producing a variety of floating and sinking aquatic feeds. It excels particularly in high-volume applications like freshwater floating feeds and sinking shrimp feeds with throughputs of 10 to 20 t/h.

Performance Characteristics

01 Robust Stability and Class-Leading Throughput

Engineered for longevity, this extruder features an optimal L/D ratio of 13.1:1. Critical components, including bearings and oil seals, are sourced from top brands to guarantee stable operation and maximum lifespan. Through optimized screw design, the machine delivers a floating aquafeed capacity that is over 10% higher than comparable models, all while maintaining an impressively low power consumption of just 20 to 23 kWh per ton of feed.

02 Guaranteed Pellet Quality and Consistency

The system achieves superior pellet output. By combining highly efficient conditioning, advanced screw configuration, and CFD simulation, the extruder optimizes the discharge and die hole distribution. This meticulous control yields highly uniform pellets, demonstrated by an extremely low expansion coefficient variance of ≤0.1 and a gelatinization degree surpassing 95%.

03 Broad Versatility at Reduced Cost

This machine offers an extensive processing range, handling most high, medium, and low-grade floating and sinking formulas. It is also capable of producing small floating pellets using 0.6mm–1mm dies. Crucially, the SJPS series delivers the product quality and cost-effectiveness of a twin-screw extruder but at a significantly lower initial investment and operational expense.

04 Advanced Automation for Consistent Production

The extruder utilizes a modular intelligent control system that automates virtually every step of the process. Standardized, one-click functions manage tasks like system feeding, preheating, conditioning, startup, shutdown, and cleaning. This comprehensive automation minimizes manual errors and labor, ensuring consistent product quality with every batch.
