Fermentation tank set

Abstract

The invention discloses a fermentation tank set, which comprises a main tank body, a sealable tank body and channels connecting the main tank body and the sealable tank body. The position relation between the main tank body and the sealable tank body is that the sealable tank body is below the main tank body or on the side of the main tank body. At least two channels are provided. One of the two channels is the channel where a fermentation liquid in the main tank body enters the sealable tank body under action of gravity and gas generated in the sealable tank body enters the main tank body. The other one is the channel where the fermentation liquid in the sealable tank body enters the main tank body under pressure. In the invention, gas generated in the fermentation process is used as an impetus: on the one hand, grape skin at the top of the fermentation tank is agitated so that the grape skin is contacted with the fermentation liquid adequately so as to prevent pomace cap formation. On the other hand, the fermentation liquid flows to the main body from the sealable tank body so that the fermentation liquid can be circulated between the main tank body and the sealable tank body under combined action of gravity and pressure of the fermentation gas.

Description

Technical field [0001] The invention belongs to the field of fruit wine brewing equipment, and particularly relates to a fermentation tank group for wine brewing. Background technique [0002] In wine fermentation production equipment, there are many types of fermentation tanks, but no matter which type of fermentation tank, there is a basic premise, that is, the fermentation tank contains at least one container suitable for holding fermentation liquid. It is designed as a sloping bottom or an inverted cone bottom, and the tank has at least one inlet and at least one outlet on the side wall or bottom of the tank. [0003] Generally, the grape fermentation liquid basically includes grape juice, grape skins, grape seeds, and a small or trace amount of grape stems. During the fermentation process of the above-mentioned fermenter, the grape skins will gradually rise to the top of the fermentation liquid. As time goes on, part of the skin layer will exceed the liquid surface and cannot...

Problems solved by technology

[0009] Although the fermenter provided by 97182142.9 has many advantages as above, it still has disadvantages, such as during the fermentation process from the lower part of the clapboard to the bottom of the tank, the fermented liquid is in a relatively static state, so the temperature in the lower part of the fermenter is difficult to control evenly; The liquid cannot be circulated during the entire fermentation period, and there is also the problem of uniform fermentation. For example, when the grape skins float, the fermentation liquid in the middle and lower parts of the fermenter cannot contact the grape skins; secondly, although the device in the fermenter is larger than the traditional fermenter In order to reduce, but still not enough; the last point is that the transformation of the traditional equipment still in operation in the existing winery seems powerless
