3. The screw has a strong pumping effect, the material viscous diffusion effect is stronger, the propulsion speed is faster, the product quality is stable.
4. No adhesive is needed for processing floating feed, and the stability can be maintained in the water for more than 12 hours.
5. The palatability of feed is improved. After puffing the feed material, the flavor increases, palatability improves, and can stimulate the appetite of animals and birds.
