Feed Extruder Machine

A feed extruder is a machine that uses high temperature and pressure to puff and shape raw materials. It’s widely used for producing expanded feeds such as pet food and fish feed. Powered by a screw mechanism, the raw material is pushed through a die, where it’s heated, expanded, and formed. This process improves feed palatability and enhances nutrient absorption, making the extruder an essential tool in modern feed production.

Advantages of the Feed Extruder

1. Improved palatability: The extrusion process enhances the texture and flavor of the feed. It also promotes starch gelatinization and breakdown, encouraging animals to eat more while improving digestion and nutrient uptake.
2. Easier digestion and absorption: High temperature and pressure destroy plant cell walls and reduce crude fiber content. As a result, animals can absorb more nutrients more easily.
3. Enhanced feed hygiene: The high temperature and pressure during extrusion effectively eliminate mold, bacteria, and fungi in the raw materials. This significantly improves feed hygiene and helps reduce the risk of diarrhea, enteritis, and other digestive diseases in animals.
4. Less water pollution: Aquatic extruded feed floats or sinks slowly and doesn't dissolve easily. This helps reduce leftover fermentation and prevents water pollution caused by feed breakdown, supporting a more stable farming environment.
5. Longer shelf life: During extrusion, oils are released and form stable lipid complexes. This improves fat utilization and slows down rancidity, allowing the feed to be stored for longer periods.

Beyond the benefits of the extrusion process itself, our feed extruder is also well-designed on the hardware side:

• The screw and sleeve are made from high-temperature, wear-resistant alloy steel. They are heat-treated for improved durability and longer service life.
• A single-screw design keeps the structure compact. It uses fewer parts, which means fewer failures and easier cleaning and maintenance.
• The extruder has an extended screw and barrel. This increases retention and heating time for more thorough expansion.
• Core components are carefully selected for durability. This helps lower long-term operating costs while keeping the price competitive—without compromising quality.
• Equipment parameters and die specifications can be customized as needed. Technical support and after-sales service are available to ensure reliable long-term operation.
