Description

Cleaning device of fermentation tank

Technical Field

The utility model relates to a belt cleaning device of fermentation cylinder belongs to fermentation cylinder belt cleaning device technical field.

Background

Fermentation is a method for producing useful biological products for human beings by utilizing certain functions of microorganisms and active isolated enzymes, and the main equipment in the fermentation process is a fermentation tank; in modern society, fermentation tanks are widely used for fermentation of materials in the industries of fine chemical engineering, bioengineering, food, beverages, chemical engineering, pharmacy and the like, and industrially refer to equipment for performing microbial fermentation, mechanical stirring and fermentation on materials. The fermenter has a main body which is generally a cylindrical column made of stainless steel plate and has a volume of 1m3 to several hundreds of m³In the design and processing, attention should be paid to the structure is tight and reasonable, the steam sterilization can be endured, certain operation elasticity is realized, the internal accessories are reduced as much as possible (dead angles are avoided), the material and energy transfer performance is strong, certain adjustment can be carried out so as to facilitate cleaning and reduce pollution, and the steam sterilization machine is suitable for the production of various products and reduces energy consumption. Because the biological fermentation needs to use strains, the inside of the tank body needs to be cleaned and sterilized before the fermentation, so that the pollution generated in the fermentation process is prevented, and the product quality is prevented from being influenced; after the fermentation is finished, some stains of the fermentation liquid, especially the inner wall of the fermentation tank, remain in the fermentation tank, and if the stains are not cleaned, the subsequent fermentation cannot be carried out. Because the opening of the tank body is smaller, the cleaning easily causes the omission of dead angles, and a special tool is needed to ensure the cleaning effect. The cleanliness of the existing fermentation tank is very high, once the fermentation tank is not cleaned, the residual substances in the fermentation tank can influence the next fermentation, and therefore the cleaning work is particularly important. The traditional fermentation tank cleaning method generally adopts a high-pressure water gun to wash by manpower from a manhole on the top of the tank or clean by the high-pressure water gun when personnel enter the tank. The method has the defects that the tank top is manually washed, so that the middle part and the bottom part of the tank, the back surface of a middle bearing or a stirring paddle and other parts are not easy to clean in place, and cleaning dead angles are easy to generate. The personnel get into jar interior washing and have the potential safety hazard, wash inhomogeneous. Some cleaning devices are also produced in the market at present, so that the volume is large, and the operation is inconvenient when the cleaning device is used.

However, as the volume of the fermentation tank increases, the radial width and depth of the fermentation tank increase, the cleaning force of a nozzle or a tank washer installed at the upper part of the tank body is limited, the inside and the lower part of the tank body are difficult to clean incompletely, and the water consumption and the electric quantity are large. Wash small-size fermentation cylinder and have certain degree of difficulty, often need unpack the jar body apart, reassemble after the brush sanitization, the equipment is finished the back and is tested jar body leakproofness, guarantees sealed complete. The sealing element of the tank body is damaged by repeated disassembly and assembly of the fermentation tank, and the service life of the fermentation tank is greatly shortened; the cleaning mode does not have a uniform professional way, most people only carry out simple operations such as wiping, time and labor are wasted, the efficiency is low, and the effect is not good.
