Our twin screw extruder machine can not only handle with plastic material, but also animal food. The material inside is high quality steel which ensures the safety and health of the food.
The side feeder is usually prepared for powder material. Some additives can not endure high temperature for long time, so we can use this side feeder feeding such material from the second or later barrel.
Water stranding cooling pelletizing system or air cooling system or belt conveyor are all common methods to cool down the dog food product.
