Description

Technical Field

[0001] The invention relates to the technical field of lactic acid bacteria fermentation, and more specifically to a lactic acid bacteria powder fermentation and cultivation device. Background Art

[0002] Lactic acid bacteria is a general term for a type of bacteria that can use fermentable carbohydrates to produce large amounts of lactic acid. This type of bacteria is widely distributed in nature and has rich species diversity, including at least 18 genera and more than 200 species. Except for a very small number, most of them are essential bacteria in the human body and have important physiological functions. They are widely present in the human intestine. Lactic acid fermentation refers to the process of using lactic acid bacteria to break down carbohydrates into lactic acid. Stirring is an important part of the lactic acid fermentation process. Failure to fully stir will lead to uneven distribution of lactic acid bacteria and affect the fermentation effect.
