Description

Technical Field

[0001] The utility model relates to wine fermentation equipment, in particular to a wine fermentation tank cover with a pressure relief function. Background Art

[0002] The wine's malic acid-lactic acid fermentation, clarification and stabilization after leaving the oak barrel, and other brewing processes need to be carried out in stainless steel fermentation tanks. In order to ensure good sealing and avoid bacterial infection during fermentation and wine storage, traditional fermentation tanks usually add a soft gasket between the tank cover and the tank mouth. Although this method can ensure that the wine can be fermented and stored under relatively closed conditions, ensure good sealing and avoid bacterial infection during fermentation and wine storage, and effectively ensure the good sanitation of the wine during storage, there are also some inconveniences and hidden dangers: During the storage process, sampling and other operations will increase the negative pressure in the wine storage tank or fermentation tank, resulting in an imbalance of internal and external air pressure, making it difficult to open the tank cover, causing inconvenience in operation. What's more, the gasket needs to be destroyed to open the tank cover, which also causes unnecessary cost increases and equipment losses.

[0003] The prior art provides corresponding pressure relief holes on the cover of the fermentation tank to periodically release the negative pressure gas in the fermentation tank to balance the internal and external pressures. However, the pressure relief operation causes the gas inside and outside the tank to circulate, which can easily cause health and safety problems such as bacterial infection.

[0004] Therefore, on the basis of ensuring the sanitary and safe performance of fermentation in the fermentation tank, designing a wine fermentation tank cover that can effectively solve the negative pressure problem of the fermentation tank and timely relieve the pressure of the fermentation tank is the research purpose of the utility model.
