Technical Field
[0001] This utility model relates to the field of lactic acid bacteria fermentation tank technology, specifically to a lactic acid bacteria fermentation tank that is easy to clean. Background Technology
[0002] Lactic acid bacteria fermentation tanks are equipment specifically designed for lactic acid bacteria fermentation. They provide optimal environmental conditions such as nutrients, pH, temperature, and oxygen supply to promote the growth of lactic acid bacteria and the production of lactic acid. These tanks are typically made of stainless steel and feature a highly efficient stirring system and a precise control system, enabling automated operation and meeting the fermentation needs of different lactic acid bacteria. Lactic acid bacteria fermentation tanks are widely used in various industries such as food, beverages, and biomaterials, and are essential equipment for the production of fermented foods and biomaterials. To ensure their normal operation and extend their service life, regular maintenance and upkeep are required. Therefore, it is necessary to clean the interior of the lactic acid fermentation tank. CN218435703U discloses a lactic acid bacteria fermentation tank that is easy to clean. By using the fermentation tank body, support legs, top sealing cover and stirring and cleaning components in combination, it can achieve good stirring and cleaning, resulting in better cleaning effect and solving the problem of poor cleaning in existing models. This easy-to-clean lactic acid bacteria fermentation tank has the advantage of good cleaning effect. However, the scraper in this lactic acid fermentation tank cannot clean its inner wall longitudinally, which can easily lead to cleaning dead corners, thereby reducing the cleaning effect of the lactic acid bacteria fermentation tank and bringing certain adverse effects to practical use. Therefore, it needs to be improved. Utility Model Content
