After adopting the above structure, the material is uniformly fed into the conditioner through the frequency conversion screw feeder. In the conditioner, the material is driven by the rotation of the paddle to fly, directly heated by steam, and water can be added to adjust the humidity and temperature of the material during curing. After passing through the conditioner, the material enters the material inlet of the extruding cylinder from the connecting cylinder, and is transported to the discharge plate after being rotated, conveyed, extruded, cut and kneaded by the blocking bolt. At the same time, it can be adjusted by steam or cooling water in the interlayer of the puffing chamber Reach the ideal puffing temperature requirement. The material is made into various shapes through a special-shaped discharge template, and cut by a frequency conversion cutter. At the moment of mold ejection and blanking, the pressure is released suddenly, causing the material to expand. The surface of the finished product is smooth, the degree of gelatinization is high, and it stays in water for a long time. It can be made into floating, semi-sinking or sinking aquatic products and pet feeds, suitable for different aquatic products and pet feeding needs.
