Description

Technical Field

[0001] The utility model relates to the field of cleaning and sterilizing devices, in particular to a cleaning and sterilizing device for a fermentation tank. Background Art

[0002] Fermentation tank refers to the device used for microbial fermentation in industry. Its main body is generally a cylindrical cylinder made of stainless steel plate, with a volume ranging from 1m3 to hundreds of m3. In design and processing, attention should be paid to strict and reasonable structure.

[0003] At present, a Chinese utility model with the announcement number CN220116530U discloses a steam cleaning and sterilizing device for a fermentation tank, including a fermentation tank and a steam pipe; a hole for inserting the steam pipe is provided on the tank wall of the fermentation tank; a vertically connected sleeve with the same inner diameter is provided on the outside of the hole; the steam pipe passes through the sleeve and the hole and is slidably connected; a steam port is provided on the side wall of the front end of the steam pipe, and a front sealing head is provided at the end; a rear sealing plate is provided at the rear end of the steam pipe; a spring elastically connected between the rear sealing plate and the tank wall is provided; a push oil top is provided behind the rear sealing plate; the end of the steam pipe passes through the rear sealing plate and is connected to the steam generating device through a metal hose. The utility model has a simple structure and is easy to use. It will be isolated from the inside of the tank body when not in use, which effectively solves the technical problem that the steam cleaning device of the fermentation tank in the prior art is prone to blockage.

[0004] To sum up, although the cleaning and sterilization device can prevent blockage, there are still certain problems when using it. For example, the cleaning and sterilization device is installed on the tank wall of the fermentation tank. When conveying the cleaning and sterilization material, it can only clean and sterilize a part of the internal area of ​​the tank body, and other areas need to wait for the diffusion and permeation of the cleaning and sterilization device material. In addition, the adhesions in other areas of the inner wall of the fermentation tank lack the strong impact force of the cleaning and sterilization material, and it is easy to have adhesion and unclean cleaning, resulting in slow speed and poor effect when cleaning and sterilizing the inside of the fermentation tank. At the same time, the cleaning and sterilization device can only perform a single steam delivery, and cannot deliver water and disinfectant. The treatment effect of some stubborn and high-temperature resistant bacteria is poor, and after cleaning and sterilization, the inside of the tank body cannot be quickly dried, and the subsequent fermentation production work cannot be accelerated.
