[0002] Conventional devices for preparing bio-fermented feed for laying hens are special equipment designed for the efficient and safe production of laying hen feed. This device uses bio-fermentation technology. Through the metabolic action of microorganisms, raw materials are converted into feed that is rich in nutrients and easy to digest and absorb to meet the growth and production needs of laying hens. When preparing bio-fermented feed, the selected raw materials are put into a container, and then an appropriate amount of fermentation inoculant, such as lactic acid bacteria, yeast, etc., is added. Before adding the inoculant, the inoculant should be first mixed evenly with an appropriate amount of water, and then the raw materials and the fermentation inoculant are fully mixed to ensure that each raw material can come into full contact with the fermentation inoculant. Then the mixture is placed under suitable temperature and humidity conditions for fermentation until the fermentation is completed, thus completing the preparation of the feed.
