Features of Industrial Twin Screw Extruder
Zoned Temperature Control System
The manufacturers is equipped with 3-5 independent temperature control zones. The temperature of each zone can be adjusted according to the formulation characteristics. Precise temperature control helps improve starch gelatinization and protein solidification, making pet food easier to digest and absorb.
Stable Feeding
Equipped with a variable frequency speed control system. Feeding speed, manufacturer, screw speed, and cutting speed can all be adjusted independently. This avoids problems such as clogging, material shortage, or unstable expansion caused by unstable feeding.
Self-cleaning and low-residue
The screw structure has a self-cleaning function, which reduces material residue during operation. This helps companies maintain a hygienic production environment and reduces cross-contamination between different formulations.
Food-grade materials
All parts that come into contact with raw materials and semi-finished products are made of 304 food-grade stainless steel. Compliant with international food safety production standards, suitable for long-term stable production of pet food.
Advantages of High-Performance Twin Screw Extruder
- High Molding Rate: Our twin-screw extruders feature stable extrusion pressure and uniform curing. This significantly improves the overall molding rate of products and reduces the generation of defective products.
- Low cost: Optimized transmission structure and heating system reduce unnecessary energy loss. Longer service life for wear parts such as screws and cutting tools reduces replacement frequency, thus saving on long-term operation and maintenance costs.
- Easy to operate: The user interface is intuitive and clear, allowing workers to quickly learn how to use it after simple training. The system can operate continuously and automatically, reducing manual intervention and improving overall production efficiency.
- Capable of producing a variety of formulations: Whether it’s a conventional grain-based, high-meat, high-oil, or grain-free formulation, the twin-screw extruder manufacturer maintains stable extrusion performance. Problems such as material slippage, arching, or discharge difficulties will not occur.
Working Principle of Extruder Press
- Feeding and Conveying Stage: Mixed raw materials are fed evenly into the extrusion chamber via a variable-frequency system. The twin screws rotate synchronously, ensuring smooth and continuous material flow without blockage.
- Mixed Shearing: The intermeshing screws provide thorough shearing and mixing, achieving a uniform blend of all components.
- Heating, Curing, and Pressurization Stages: Materials are heated by external and friction-generated heat. Rising pressure promotes starch gelatinization and protein restructuring, preparing the mixture for shaping.
- Extrusion Molding: The material is pushed through the die under controlled pressure and temperature. The mold determines the product’s final shape—round, bone-shaped, or strips.
- Expansion and Fixed-Length Cutting: Upon exiting the die, rapid pressure release causes expansion. A rotating knife cuts the product into uniform lengths before sending it to the drying system.
FAQs
It can produce dry dog food, cat food, fish feed, bird feed, rodent feed and various expanded pet snacks by changing molds and adjusting process parameters.
Yes, we provide 12-month warranty, lifetime technical support and quick spare parts supply service.
Under normal use and maintenance conditions, the service life of the screw and barrel can reach 2-3 years or more. The specific service life depends on the raw material formulation and production cycle.
