Description

Technical Field

[0001] The utility model relates to the technical field of beer fermentation, in particular to a beer fermentation tank. Background Art

[0002] The beer fermentation process is the normal life activity of brewer's yeast under certain conditions, using the fermentable substances in the wort. The product of its metabolism is the desired beer. Due to the different types of yeast, the fermentation conditions and product requirements, flavors are different, and the fermentation methods are also different. The modern fermentation method is usually to place the corresponding fermentation material into the corresponding fermentation tank, and then discharge the solution produced by the fermentation from the bottom to obtain the raw pulp, and then carry out subsequent processing.

[0003] However, in actual use, since the materials accumulate at the bottom of the device, the materials inside it are usually unable to move freely. Therefore, in areas where the yeast distribution is uneven or the oxygen environment is inconsistent, the fermentation speed will also be inconsistent. Therefore, it is necessary to stir the materials evenly before fermentation, and it is also necessary to control the materials during fermentation. Moreover, a large amount of gas will be produced during fermentation, which will cause a large amount of foam to appear on the top of the fermentation liquid. In order to eliminate the foam, a defoaming agent needs to be added. Adding additional additives will easily affect the flavor of the fermentation, so a beer fermentation tank that can effectively remove foam is needed. Utility Model Content
