[0042] The cross section of the belt moving block 74 is circular.

[0043] Working principle and use process of the utility model:

[0044] Firstly, the liquefied carbon dioxide in the liquefied carbon dioxide storage tank 1 enters the second feeding pipe 22 through a pipeline, and then enters the heat exchange pipe of the first tube heat exchanger 2; at the same time, the refrigerant liquid in the refrigerant liquid storage tank 6 enters the fermentation tank 5 for cooling, and then enters the valve cavity of the first tube heat exchanger 2 through the first discharging pipe 23, and finally returns to the refrigerant liquid storage tank 6 through the first feeding pipe 21; in this way, the liquefied carbon dioxide flowing in the heat exchange pipe and the refrigerant liquid in the valve cavity exchange heat energy initially, since the liquefied carbon dioxide needs to absorb a large amount of heat in the process of gasification, the refrigerant liquid is used to absorb the heat released in the process of gasification, so as to help the liquefied carbon dioxide complete the gasification.

[0045] Subsequently, the carbon dioxide in the heat exchange tube of the first tube heat exchanger 2 after preliminary gasification enters the third upper feeding pipe 31 through the second lower feeding pipe 24, and then enters the valve cavity of the second tube heat exchanger 3; at the same time, the warm water in the recovery water tank 4 enters the heat exchange tube of the second tube heat exchanger 3 through the fourth lower feeding pipe 34, and finally returns to the recovery water tank 4 through the fourth upper feeding pipe 32; in the process of the flow of the warm water, the heat energy exchange between the warm water in the heat exchange tube and the carbon dioxide in the valve cavity occurs, so that the carbon dioxide is completely gasified; finally, the completely gasified carbon dioxide enters the fermentation tank 5 through the third lower feeding pipe 33 for pressure preparation; in this way, by arranging the first tube heat exchanger 2 and the second tube heat exchanger 3, and using the refrigerant liquid to preliminarily warm the liquefied carbon dioxide, and then using the warm water to further warm, the carbon dioxide gasification state is achieved, and steam does not need to be supplied all the time, so that the effect of saving energy is realized.

[0046] In addition, in the process that the refrigerant liquid in the refrigerant liquid storage tank 6 enters the fermentation tank 5, the temperature inside the fermentation tank 5 is low at this time, so that the water droplets are condensed on the outer wall of the fermentation tank 5; the worker starts the rotating motor 77, and then drives the driving gear 75 and the driven gear 76 meshing with the driving gear 75 to rotate; and then drives the rotating screw 73 to rotate around the axis thereof, and the rotating rotating screw 73 drives the moving block 74 to move up and down along the sliding groove 721, so that the water removal ring 71 connected with the moving block 74 through the connecting block 78 also moves up and down along the rotating screw 73, and the water removal ring 71 moving up and down removes the water droplets on the outer wall of the fermentation tank 5, so as to prevent the excessive water in the fermentation tank 5 from corroding the metal surface of the fermentation tank 5, and then ensure the quality of the fermented beer.
