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.

[0025] See attached figure 1 , 2 , 1 represents the entire fermenter group.
[0026] The fermentation tank group 1 of the present invention includes at least two tank bodies with a certain positional relationship and a channel connecting the two tank bodies. One of the two tank bodies is the main tank body 2, and the other tank body is the Airtight tank 3; the positional relationship between the main tank 2 and the sealable tank 3 is that the free liquid surface of the main tank 2 is higher than the free liquid surface of the sealable tank 3; the passage can make the main tank The fermentation liquid 8 in the body 2 flows into the sealable tank 3 under the action of gravity. The passage can make the gas 9 in the sealable tank 3 flow into the main tank 2, and the passage can make the sealable tank The fermentation liquid 8 in the body 3 flows into the main tank 2 under pressure.
[0027] The positional relationship between the main tank body 2 and the sealable tank body 3 is that the sealable tank body 3 is under or on the side of the main tank body 2.
[0028] The main tank 2 of the present invention is a container with an inclined bottom 17 or an inverted truncated cone bottom 18 and is suitable for holding fermentation liquid 8. The bottom of the main tank 2 is supported by legs 28. In the lower part of the main tank wall, a juice outlet 13 and a lower manhole 31 are respectively provided, a thermometer 32 is installed in the middle of the main tank wall, and a discharge port 12 is provided at the bottom of the main tank body 2. Of course, usually To ensure the fermentation temperature, a jacket is often set outside the fermentor or a heating or cooling coil (not shown in the present invention) is set in the tank.
[0029] The fermentation broth 8 is composed of grape juice 23, grape skin 24, grape seeds 25, and other substances such as yeast, pectinase and chemical additives. The fermentation broth 8 is introduced into the main tank 2 through the inlet 11.
[0030] The sealable tank 3 of the present invention adopts a conical tank top 19 or an elliptical tank top 20, with a feed inlet 22 on the top, and a safety valve 38 on the top of the sealable tank 3. A leg 30 is provided at the bottom of 3 for support, a pressure gauge 45 is installed on the top of the tank, and a temperature gauge 46 is installed on the tank wall.
[0031] The bottom of the sealable tank 3 is an inverted conical bottom 26 or an inclined bottom 27. The bottom of the tank is provided with a discharge port 15, and the discharge port 15 is connected to a discharge valve 16.
[0032] The main tank body 2 means that the fermentation gas 9 in the tank body can freely escape; the sealable tank body 3 refers to the carbon dioxide gas 9 produced by the fermentation liquid 8 in the tank body by closing the valve on the tank body A tank that can generate pressure in the tank under the action, or a tank that can generate pressure in the tank by closing the valve on the tank and introducing a certain pressure of carbon dioxide or nitrogen from the outside.
[0033] In this embodiment, the channel is divided into at least two channels 6 and 7, and the channel 6 and channel 7 respectively connect the main tank 2 and the sealable tank 3; The passage 6 allows the fermentation liquid 8 in the main tank 2 to enter the sealable tank 3 under the action of gravity, and the passage 6 can also enable the gas 9 in the sealable tank 3 to enter the main tank 2; The aforementioned channel 7 allows the fermentation liquid 8 in the sealable tank 3 to enter the main tank 2 under pressure.
[0034] in figure 1 The positional relationship between the main tank body 2 and the sealable tank body 3 is an up-and-down structure, that is, the sealed tank body 3 is below the main tank body 2, and the main tank body 2 and the sealable tank body 3 are connected by a channel 6. The said channel 6 is formed by the outlet 12 at the bottom of the main tank and the inlet 22 of the sealable tank directly connected by the valve 4; figure 2 This is the second structural modification of the fermentation tank group of the present invention. It changes the plane position of the main tank body 2 and the sealable tank body 3 from the upper and lower positions to the left and right positions, that is, the sealed tank body 3 is on the side of the main tank body 2. The passage 6 communicating between them is also changed. The passage 6 described here can also be formed by connecting the opening 21 on the tank wall of the main tank 2, the valve 4, the pipe 10 and the sealable tank inlet 22.
[0035] A discharge port 42 is provided on the wall of the sealable tank 3, and the discharge port 42 is set at the lower or bottom of the wall of the sealable tank 3, and a filter screen ( 37), the channel 7 is formed by connecting the discharge port 42 of the sealable tank with the valve 5 and the pipe 14, and the other end of the channel 7 extends into the main tank 2.
[0036] On the wall of the sealable tank 3, an air inlet 29 is also provided. On the outside of the sealable tank 3, the air inlet 29 is connected to the air supply system 44 through a valve; The port 29 is connected to a detachable gas diffuser 43, which is provided with uniform small holes toward the bottom of the sealable tank 3 to form air holes.
[0037] Obviously, by opening the valve 4 on the passage 6, the main tank 2 and the sealable tank 3 can be communicated, and the fermentation liquid 8 in the main tank 2 enters the sealable tank 3 under the action of gravity; by closing the valve 4 , The fermentation liquid 8 in the main tank 2 and the sealable tank 3 are respectively located in two independent fermentation spaces. The gas 9 produced by the fermentation liquid 8 in the main tank 2 escapes freely from the top of the main tank 2, and the gas 9 produced by the fermentation liquid 8 in the sealable tank 3 increases the pressure in the sealable tank 3 When the valve 5 is opened, due to the effect of pressure, the fermentation liquid 8 in the sealable tank 3 flows into the main tank 2 through the channel 7. At the same time, as the fermentation liquid 8 in the sealable tank 3 decreases, the A gas 9 space with a certain pressure and a certain volume is formed in the airtight tank 3. When the valve 4 is opened, the gas 9 in the airtight tank 3 enters the main tank 2 upwards along the channel 6 and is in the main tank 2. The free liquid surface is released, thereby stirring the rising grape skins 24. The fermentation liquid 8 in the main tank 2 will enter the sealable tank 3 through the valve 4 along the channel 6 under the action of gravity, for the next cycle.
[0038] Obviously, because the above-mentioned circulation continues continuously, the circulation of the fermentation liquid 8 and the spraying of the leather cap are promoted. At the same time, the gas 9 continuously stirs the grape skin 24 on the top of the main tank 2 to promote the grape skin 24 and the fermentation liquid 8 mixing. At the same time, the grape seeds 25 on the bottom 18 of the main tank 2 will enter the sealable tank 3 with the fermentation liquid 8, and fall onto the inverted cone bottom 26 or the inclined bottom 27. By opening the valve 16, that is The grape seed 25 can be drained.
[0039] Through the air inlet 29 provided on the sealable tank body 3, the required gas 9 can be added artificially at the beginning or the end of the fermentation, and it can also be determined whether to pass in air according to the progress of the fermentation. Obviously, when the whole fermentation tank group 1 When used as a wine aging storage tank, the gas required for aging, such as nitrogen or carbon dioxide, can also be introduced through the air inlet 29.
[0040] In this embodiment, when the entire fermentation tank group 1 is used as a wine aging storage tank, the valve 4 between the main tank 2 and the sealable tank 3 is opened, and the mash will gradually enter the sealable tank 3, and The main tank 2 contains clear wine, which is more convenient for the separation of liquor and mash.
[0041] figure 2 In the fermenter group shown, a filter screen 37' is provided on the inside of the main tank 2 at the outlet 21.
[0042] The outer circumference of the pipe 14 on the channel 7 is provided with a cooling or heating sleeve 39, and the sleeve 39 is provided with a heat exchange medium inlet 40 and a heat exchange medium outlet 41. Since the fermentation broth 8 is continuously circulated, it is replaced here. The efficiency of heat exchange is higher than that of the outer jacket or the inner coiled tube of the main tank 2, and the equipment cost is greatly reduced. For the same reason, other high-efficiency heat exchangers such as plate heat exchangers can be installed on the pipe 14.
