What is the reason for the poor performance of the extruder?

                     Before entering the extruder, remove impurities in the material to prevent stones and mud from wearing and breaking the screw conveyor and screw of the extruder. It can also improve the quality of the product. When the moisture in the raw materials is too high, it is easy to choke when cutting, the moisture cannot be discharged in a short period of time, the puffing cannot be made, and the dog food is soft and not brittle. The high moisture content shortens the shelf life of the dog food. When the moisture content is too low, it will also reduce the puffing degree of dog food, consume a lot of energy, and affect the output.

                     In order to maintain the quality of the puffed products and the non-stop operation of the puffing machine, the needs of the puffing machine must be met when discharging materials. If the feed is insufficient, the puffing effect will be unsatisfactory. Feeding too much material will easily block the machine and reduce production volume. The puffing of dog food is divided into dry process and wet process. The wet process greatly improves the output and palatability of dog food through tempering technology, and is increasingly used and selected.
