In the production and processing of organic fertilizers, it is necessary to add biological fermentation bacteria to the organic fertilizer raw materials for fermentation. During the fermentation process, in order to ensure the fermentation effect of the fertilizer, it is necessary to ensure that the fertilizer is in contact with the air. For example, the patent with publication number CN218969123U discloses a fermentation device for agricultural fertilizer production, including a fermentation tank, a stirring structure and an aeration structure. The fermentation tank is provided with a fermentation chamber, and the top of the fermentation tank is provided with a top A cover is provided, a feed port and a water inlet are respectively installed on both sides of the top cover, a driving chamber is provided in the center of the top cover, a plurality of vents are opened on the upper side wall of the fermentation tank, an electric heating plate is installed at the bottom of the fermentation tank, a discharge port is provided on one side of the bottom of the fermentation tank, and a discharge port valve is installed at the port of the discharge port.
