Features of High-efficiency Twin-screw Extruder
- Zoned Temperature Control System: The twin-screw extruder 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, 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 Twin-Screw Feed Extruder
- High Molding Rate: As a professional twin-screw extruder manufacturer, 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 maintains stable extrusion performance. Problems such as material slippage, arching, or discharge difficulties will not occur.
Working Principle of Pet Feed Extruder
- Feeding and Conveying Stage: The mixed raw materials are evenly fed into the extrusion chamber through a variable frequency feeding system. The two screws rotate synchronously in the same direction, forming a stable conveying channel. This continuously and evenly conveys the material forward, preventing material accumulation or blockage at the feed inlet.
- Mixed Shearing: Under the meshing action of the twin-screw structure, the material undergoes thorough shearing, friction, mixing, and dispersion. This results in a more uniform mixing of various components.
- Heating, Curing, and Pressurization Stages: Under the combined action of external electric heating and internal frictional heat generation, the material temperature steadily rises. The pressure within the cavity gradually increases, causing the starch to fully gelatinize and the proteins to denature and reorganize.
- Extrusion Molding: When material is pushed to the front die, it is extruded from the die orifice under constant pressure and temperature. The die determines the shape of the product and can be various shapes, such as round, bone-shaped, or strip-shaped.
- Expansion and Fixed-Length Cutting: After the product is extruded from the mold, the internal pressure is released instantly. Moisture evaporates rapidly, and the product expands and takes shape. A rotary cutter cuts the product into particles of a fixed length, which are then fed into a dryer for the next process.
