It is engineered for pre-treatment before extrusion in the aquafeed and pet food industries. This series offers wide adaptability to raw materials and features flexible process parameter adjustment. It performs critical functions like high-temperature disinfection, starch gelatinization, and protein structuring on compound feeds, fully preparing them for the expansion process.

Performance Characteristics

01 Extended Conditioning Time and Superior Results

The SPTZ_D model delivers significantly enhanced performance. Compared to the standard SPTZ triple-shaft conditioner, the equal-diameter design provides a 20% increase in both volume and conditioning time, ensuring deeper material cooking and superior results.

02 Optimized Water and Steam Injection

The system employs a segmented approach for superior material treatment. The upper conditioner is dedicated to rapidly adding and mixing water and steam, while the lower conditioner achieves a high filling rate to extend the crucial conditioning time. The water and steam addition uses a multi-point and co-injection structure to ensure thorough mixing with the raw materials.

03 Fully Upgraded, Leak-Proof Sealing System

The machine features a completely upgraded sealing system to ensure zero leakage. The professional shaft end seal uses multi-layer sealing for excellent performance and long service life. The door seal is constructed from embedded high-temperature resistant foamed silicone, which is durable and easy to install.

04 Simplified Operation and Maintenance

Maintenance is designed for efficiency. The door body opens up to approximately 70% of the conditioner's length for convenient cleaning, and the locking mechanism features an automatic function. The shaft end seal area provides a large replacement space, simplifying the process of replacing aged seals.

05 Variable Frequency Control on Lower Conditioner

The lower conditioner is equipped with a Variable Frequency Drive (VFD) motor. This allows the rotational speed to be adjusted online based on production capacity and formula requirements, thereby optimizing the filling rate and overall conditioning effect. An SEW gear-reducer is available as an option.
