Constant temperature fermentation device

Technical field

The utility model relates to a constant temperature fermentation device and belongs to the field of fermentation technology.

Background technique

Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microbial cells themselves, or direct metabolites or secondary metabolites. Fermentation is sometimes also called fermentation, and its definition varies depending on the occasion where it is used. Fermentation generally refers to a certain decomposition process of organic matter by organisms. Fermentation is a biochemical reaction that humans have been exposed to earlier, and is now widely used in the food industry, biological and chemical industries.
