The CJPS and R Series twin-screw extruders are specialized for the efficient production of high to medium-grade pet food products.

Performance Characteistics

01 Exceptional Stability and Reliability

The extruders are engineered for continuous, reliable operation. They feature a European-branded gearbox with high-precision gear meshing for stable power transmission. Key components, including bearings and oil seals, are sourced from top-tier suppliers for extended service life. The system is equipped with a torque limiter to actively prevent gearbox overload, ensuring safe and smooth operation of core mechanical components.

02 Guaranteed Hygiene and Food Safety

Product safety is prioritized through material selection. The machine utilizes stainless steel barrels and a sanitary base for easy cleaning and disinfection. Both the screw and liner are constructed from food-grade materials to ensure the utmost safety and hygiene of the final pet food product.

03 High Automation for Consistent Quality

The extruder features a modular intelligent control system with independent monitoring of key parameters, enabling a high degree of automation. Standardized, one-click functions manage the entire process, including system feeding, preheating, conditioning, startup (for the extruder and auxiliary devices), mechanical energy control, shutdown, and extruder cleaning. These features significantly reduce the reliance on manual labor and ensure uniform product quality.

04 Uniform Pellets with Superior Appearance

The machine is optimized for aesthetic and structural quality. CFD simulation technology is used to ensure uniform expansion of the pellets. A vertical pneumatic conveying system is employed to maintain the shape of the pellets during transport while also enhancing the hygiene of the surrounding production environment.

05 Online Bulk Density Adjustment and Formula Flexibility

The extruder uses mechanical energy control technology to adjust the internal barrel pressure in real-time. This allows for precise, customizable control over the final expansion rate and bulk density of the pellets, enhancing formula adaptability.

06 High Capacity for Fresh Meat Inclusion

When configured as the S series, the twin-screw extruder is equipped with a high-speed conditioner and a distinctive screw configuration that allows it to incorporate fresh meat at levels exceeding 135% (relative to the Dry Mix Rate or DMR). This capability offers a strong competitive advantage in the high-end pet food market.
