Description

Technical Field

[0001] This utility model relates to the field of enzyme fermentation tank technology, and more specifically, to a feeding device for an enzyme fermentation tank. Background Technology

[0002] Enzyme preparations are biological products with catalytic functions after enzymes have been purified and processed. They are mainly used to catalyze various chemical reactions in the production process. They have the characteristics of high catalytic efficiency, high specificity, mild reaction conditions, reduced energy consumption, and reduced chemical pollution. In the process of enzyme preparation production, fermentation is required in a fermentation tank. During the microbial fermentation process, due to the increasing amount of metabolic waste generated by the microorganisms, it is necessary to continuously replenish nutrients to the fermentation tank so that the microorganisms can continue to survive and divide.

[0003] A search revealed that utility model patent CN215365721U discloses a feeding device for a fermenter of multiple industrial enzyme preparations. The device includes a fermenter with a discharge pipe fixedly connected to its lower side wall. A feeding bucket is located on the left side wall of the fermenter, and a sterilization tank is located to the left of the feeding bucket. A bottom valve is fixedly connected to the lower side wall of the sterilization tank, and a steam valve is fixedly connected to the side wall of the bottom valve. A discharge valve is fixedly connected to the lower end of the bottom valve, and a connecting valve is fixedly connected to the lower end of the discharge valve. A connecting pipe is fixedly connected to the lower end of the connecting valve, and the end of the connecting pipe away from the connecting valve is fixedly connected to the upper side wall of the sterilization tank. A conveying pipe is fixedly connected to the upper side wall of the sterilization tank, with its left end located inside the sterilization tank. This patent enables the nutrient solution to be evenly distributed to all areas of the fermenter during feeding, ensuring thorough mixing of microorganisms and nutrient solution, shortening fermentation time, and improving the working efficiency of the fermenter.

[0004] However, the above patent still has the following shortcomings: although it can evenly distribute the material in the fermentation tank, it is not convenient to clean the discharge pipe, nozzle and other parts in the tank after use, which will also affect the fermentation quality of the enzyme preparation. Therefore, we have proposed a feeding device for enzyme preparation fermentation tank. Utility Model Content

The second bevel gear 16 is fixedly sleeved on the outside of the rotating tube 5.

[0028] In this embodiment, the first motor 14 drives the first bevel gear 15 to rotate, and the meshing transmission between the first bevel gear 15 and the second bevel gear 16 drives the rotating tube 5, the liquid distribution box 6 and the nozzle 7 to rotate, so that the nutrient solution sprayed by the nozzle 7 is evenly added to the inner cavity of the fermentation tank 1.
