The small and medium-sized feed machine is formed by extruding the mixed powdered feed once. It does not need to add water during the granulation process, and does not need to be dried. After natural heating up to about 80 degrees, the starch can be gelatinized and the internal granules are matured deeply. Smooth surface, high hardness, long-term storage, ideal for raising rabbits, fish, chicken, pigs, sheep, cattle and small and medium-sized feed processing plants
