Fermentation device

Abstract

The invention relates to the field of wine brewing, and in particular relates to a fermentation device. The fermentation device comprises a rack, a fermentation tank and detection devices, wherein thefermentation tank is mounted on the rack, and the detection devices are arranged on the fermentation tank; the fermentation tank comprises a tank body and a tank cover, the tank body is provided withan opening, the tank cover is detachably arranged on the tank body and can seal the opening, the tank body and the tank cover are matched, so that a sealed fermentation cavity is formed in the fermentation tank, an observation hole and an exhaust hole are formed in the tank cover, a transparent elastic film covers the observation hole, the elastic film is in sealed connection with the observationhole, and a one-way valve used for exhausting gas in the fermentation cavity is mounted at the exhaust hole; each detection device comprises a shell, a detection thin film, a pressing part and a connecting piece, the shell is inversely mounted at the observation hole of the tank cover in a manner that the opening of the shell faces downwards, the shell is connected and fixed to the tank cover through the connecting piece, and the elastic film is located in the opening of the shell. The fermentation device provided by the invention has the advantages that the sealing effect is good, and the fermentation effect can be observed visually.

Description

technical field [0001] The invention relates to the field of brewing, in particular to a fermentation device. Background technique [0002] The brewing process of Xiaoqu Qingxiang wine generally includes raw grain cooking, saccharification, fermentation, distillation, blending and other processes. Fermentation is the main stage of winemaking. The sugary raw materials themselves contain rich glucose, fructose, sucrose, maltose and other components, which can be directly converted into alcohol by the action of microorganisms such as yeast. Alcohol fermentation is a very complicated process. Microorganisms have high requirements on the environment, and microorganisms represented by yeast need to perform anaerobic fermentation, so the sealing of fermentation is particularly important. [0003] The currently commonly used Xiaoqu Qingxiang wine fermentation tank sealing method is: utilize artificially to spread film on the upper end of the fermentation tank body. During the ferm...

AI Technical Summary

Problems solved by technology

During the fermentation process, the film is in contact with the wine grains. Therefore, the film needs to be cleaned, which has the disadvantages of high cleaning intensity, high labor intensity and low degree of automation. It is urgent to propose a fermentation method with better sealing effect and high degree of automation. device
