[0002] A fermentation tank refers to an industrial device used for microbial fermentation. Its main body is generally a main cylinder made of stainless steel plates. Fermentation tanks are widely used in dairy, beverage, bioengineering, pharmaceutical, fine chemical and other industries. The tank body is equipped with an interlayer and an insulation layer, which can be heated, cooled and insulated. The inner wall of the tank is mirror polished and has no sanitary dead corners. The fermentation process of dairy products and wine is a sterile and pollution-free process. The fermentation tank adopts an aseptic system to avoid and prevent contamination by microorganisms in the air, greatly extending the shelf life and purity of the product. In the process of microbial fermentation, in order to determine the progress of microbial fermentation, it is necessary to extract the fermented product from the fermentation tank and test it. Therefore, a microbial extraction device for the fermentation tank is required.
