Pet food processing equipment uses twin-screw extrusion technology to produce dog food, cat food, dog chews, ornamental fish feed and other pet foods. It is a process that integrates mixing, conveying, shearing and kneading, steaming, cooking, sterilization, and molding. method.
Therefore, extrusion technology produces Pet food is a premium pet food.
The difference between single screw and twin screw:
1. The twin-screw yield is high, up to 98% or higher.
2. The particles are well formed, and the particle shapes are uniform. The twin-screw ejection pressure is very stable, which can ensure the formation of pellets.
3. The twin-screw can ensure no back-spray and blockage. On the other hand, the single screw is prone to overflow steam and reverse injection in the feeding area, resulting in unstable material flow and blockage of the machine and the like.
4. The twin-screw can continuously and steadily produce various small particle products. When producing particles with diameters of 2mm and below, the single-screw working condition is unstable, the yield will drop sharply, and the material type will also deteriorate.
5. The twin-screw density control is more stable and reliable. The material is melted more abundantly and uniformly in the twin-screw barrel, which can accurately control the production of floating material, submerged material and slow-sinking products.
6. The twin-screw has a wide range of adaptability to formulas, and is more adaptable to the production of high-energy formulas.
7. The twin-screw is easy to operate, and the production process is stable, etc.
In short, pet food production lines, whether single-helix or double-helix, are good choices for pet food manufacturers.
