Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, in particular to a pharmaceutical fermentation tank which is not prone to sticking. Background Art

[0002] Most of the current drugs contain organic components, which can only be obtained through microbial fermentation. Therefore, fermentation tanks are used in drug production. Fermentation tanks are devices used for microbial fermentation, which can produce antibiotics, amino acids, organic acids, vitamins and other organic substances. Microorganisms need to be stirred during fermentation. Stirring can mix air with the fermentation liquid and promote oxygen to dissolve in the fermentation liquid to ensure the supply of microbial growth and reproduction, thereby improving the fermentation efficiency of the fermentation tank.

[0003] During the use of existing fermentation tanks, due to the certain adhesion of biological raw materials, some biological raw materials will adhere to the stirring components in the fermentation tank. These biological raw materials adhered to the stirring blades are not easy to clean, which not only causes waste in production, but also needs to be cleaned before the next fermentation. At present, the stirring blades are usually removed manually for cleaning, which is not only time-consuming and laborious, but also greatly increases the time cost. Utility Model Content
