Universal wine fermentation tank

Abstract

The invention relates to a universal wine fermentation tank which is characterized by comprising a tank. The tank is integrally of a conical structure and comprises a tank body, a conical upper seal head and a butterfly-shaped lower seal head, the longitudinal section of the tank body is of a big-end-down isosceles trapezoid structure, the conical upper seal head and the butterfly-shaped lower seal head are connected to the upper side and the lower side of the tank body in a transition manner, an upper man hole is formed in the upper portion of the conical upper seal head, an elliptical lowerman hole is formed in the lower portion of the tank body, a square lower man hole is formed in the butterfly-shaped lower seal head, and a blow-down valve for eliminating residual wine and wine lees is mounted at the lowermost point of the butterfly-shaped lower seal head. The universal wine fermentation tank has the advantages that fermentation processes for red wine and white wine are taken intoaccount, and accordingly the universal wine fermentation tank not only can be used for fermenting the red wine, but also can be used for fermenting the white wine; the universal wine fermentation tank can be used for multiple purposes and is high in utilization rate; conical tank designs are favorable for natural convection of fermentation liquor, circulation of the fermentation liquor can be accelerated, the temperature of the fermentation liquor is uniform, fermentation of the red wine can be accelerated, and the temperatures can be reduced for fermentation of the white wine.

Description

technical field [0001] The invention relates to the technical field of wine fermentation tank structure, in particular to a multifunctional wine fermentation tank which can be used for both red wine fermentation and white wine fermentation. Background technique [0002] The red grapes are fermented with the skin on, and the early fermentation is maceration fermentation. The fermenter must meet the maceration requirements, and it should be able to separate the free-flowing juice. At present, there are several difficulties in the red wine fermentation process: one is that the grape pomace is easy to float on the surface of the liquid to form a cap, and the cap floats on the liquid surface so that the pigment on the grape skin cannot be fully infiltrated, and the extraction effect is not good. Ideal, the tannin and aromatic substances in the grape skin cannot be extracted, which will affect the quality of red wine. To ensure the body quality of red wine, it is necessary to e...

AI Technical Summary

Problems solved by technology

At the same time, the optimization of the tank structure can also solve the problems of red grape fermentation pomace cap hardening and bacterial contamination, as well as the problems of poor convection of grape juice in the white grape fermentation tank, poor refrigeration effect, and unstable temperature control during the fermentation process.
