Industrial enzyme preparation device

The invention discloses an industrial enzyme preparation device which structurally comprises a control table, a driver, a feeding port, a stirring barrel and a material barrel, the control table is matched with the driver in an electrical connection mode, the driver is connected with the feeding port, the stirring barrel is installed between the feeding port and the material barrel, a tray and a maintenance device are arranged on a power assisting body, and the maintenance device is connected with the control table. The tray and the maintenance device are matched on the penetrating sliding rod, when the width of the slit of the stirring hook begins to become smaller, the top of the penetrating sliding rod is extruded to be close to each other through the occlusion belt, the middle of the tray begins to protrude and be tightened, and the overall height of the maintenance device on the tray is reduced and the connection strength between the maintenance device and the tray is enhanced in cooperation with rotatio
