Description

TECHNICAL FIELD

[0001] The utility model relates to the field of liquor manufacturing fermentation, especially a liquor manufacturing fermentation sealing device. BACKGROUND

[0002] The fermentation process in liquor manufacturing refers to the process of converting sugar in raw materials into alcohol through the action of microorganisms. The fermentation sealing device is used to ensure the sealing of the fermentation environment, prevent bacterial infection, and control the fermentation conditions during the fermentation process of liquor. The unique structure and material selection of these fermentation containers ensure the stability and efficiency of the fermentation process, thereby affecting the final flavor and quality of the liquor. Liquor fermentation is an anaerobic process that needs to be carried out in a closed environment. If air enters the fermentation environment, the anaerobic fermentation of yeast will be inhibited, and aerobic fermentation will occur instead. This not only leads to a decrease in alcohol production, but also affects the flavor of the liquor. The sealing device can ensure that the fermentation environment is in an oxygen-free state, thereby ensuring the quality and flavor of the liquor.
