[0002] Poultry feed is a nutrient specially formulated for breeding poultry, such as pigs and chickens, to meet their physiological needs such as growth, egg production, and meat production. The feed usually contains protein, energy, small peptide organic trace elements, plant protease hydrolysis and chelated trace elements, etc., to meet the needs of livestock and poultry for various nutrients and facilitate poultry absorption.

[0003] At present, when granulating feed, it is usually necessary to crush, premix and mix the raw materials of the feed, so that the mixed raw materials enter the granulator for granulation. However, most of the granulators currently usually granulate by extrusion. After granulation, the particles need to be dried, cooled and shaped, and the particles need to be screened. Most of the granulators dry first and then screen, which affects the production efficiency.
