[0002] In the process of beer brewing, beer yeast needs to be added to the wort to carry out normal life activities under certain conditions. The product of its metabolism is beer. In order to achieve this process, the proofing tank is used to provide an ideal environment for the growth and reproduction of microorganisms. Its basic structure includes a tank body, a stirrer, a cooling device, a heating device, an air distribution device, a temperature and pressure control system, etc. The tank body is the main part of the proofing tank, usually made of stainless steel or other corrosion-resistant materials, and is used to hold the fermentation liquid. The function of the stirrer is to mix the fermentation liquid evenly to ensure the uniform growth of microorganisms. The cooling device and the heating device are used to adjust the temperature of the fermentation liquid to meet the growth needs of different microorganisms. The air distribution device is used to supply sufficient oxygen to the fermentation liquid to meet the breathing needs of microorganisms. The temperature and pressure control system is used to accurately control the temperature and pressure during the fermentation process to ensure the normal growth of microorganisms. Cooling plays a vital role in the wort fermentation process in the proofing tank, and the conical proofing tank is suitable for bottom fermentation and bottom fermentation. If the cooling device cannot cool these two parts well, it will greatly affect the brewing results of beer. Utility Model Content

The lower cold box 22 is a belt-shaped structure. The lower cold box 22 is conically enclosed and coated on the outer side of the lower end of the inner tank 12. The upper cold box 21 is in a strip-shaped structure, and the upper cold box 21 is cylindrically enclosed and covered on the upper outer wall of the inner tank 12. A accommodating groove 31 for accommodating the horn manhole 3 is provided between the left and right ends of the upper cold box 21; the water inlet 23 passes through the outer tank 11 and is connected to the bottom of the left end of the lower cold box 22, the lower end of the connecting pipe 24 is connected to the top of the right end of the lower cold box 22, the upper end of the connecting pipe 24 is connected to the bottom of the upper cold box 21, and the water outlet 25 is connected to the top of the upper cold box 21 and passes through the outer tank 11.
[0017] Furthermore, the distance between the outer tank 11 and the inner tank 12 is not less than 30 mm, and the outer wall of the outer tank 11 is provided with an air inlet 111 and an air outlet 112 which are connected to the outer wall and correspond to each other.
[0018] Description of the working method of this utility model:
[0019] The yeast proofing tank adopts this structure, the top of the main tank 1 is provided with a dry dosing device, the middle is provided with a sampling port, a trumpet manhole 3 and a pressure gauge, and the bottom is provided with a slag discharge port and a material discharge port, which are the most basic functions of the proofing tank. The main tank 1 with a cylindrical upper end and a conical lower end is divided into an outer tank 11 and an inner tank 12. The inner tank 12 is used to store wort and yeast for fermentation. The gap between the outer tank 11 and the inner tank 12 can isolate the external air and temperature, ensuring that the inner tank 12 always maintains a relatively stable state during use. In order to achieve cooling in the main tank 1, the upper and lower ends of the inner tank 12 are respectively coated with The strip-shaped upper cold box 21 and the lower cold box 22 are connected to the lower cold box 22 through the water inlet 23. The lower cold box 22 has a left bottom. After the water flows into the lower cold box 22, it will gradually fill up the lower cold box 22. Since the left and right ends of the lower cold box 22 correspond to each other and do not contact each other, the lower cold box 22 will completely cover the lower end of the inner tank 12 to achieve all-round cooling of the lower end. The water that completely fills up the lower cold box 22 will enter the connecting pipe 24 at the upper end of the lower cold box 22 and enter the bottom of the upper cold box 21. Similarly, the water will also fill up the inner cavity of the upper cold box 21, and the left and right ends of the upper cold box 21 are provided with containers. The slot 31 can be used for the installation of the horn manhole 3, so as to realize the cooling of the upper cold box 21 within the maximum range, and the water that has been circulated and cooled in the lower cold box 22 and the upper cold box 21 flows out from the water outlet 25 to complete the cooling of the inner tank 12. After the beer is brewed and the contents in the inner tank 12 are emptied, in order to avoid the temperature in the outer tank 11 and the inner tank 12 being inconsistent with the outside temperature, resulting in a large temperature difference between the inside and the outside after the next batch of brewing enters the inner tank 12, the brewing environment changes, and thus the slightly different brewing results will appear, which will cause the brewing results of each batch to be unbalanced. As predicted, the distance between the outer tank 11 and the inner tank 12 is limited to no less than 30 mm. A distance less than this distance will cause the external ambient temperature to affect the cooling effect of the cooling component 2, while a distance greater than this distance will minimize the impact of the ambient temperature on the inner tank 12. In addition, after brewing is completed, the air inlet 111 and the air outlet 112 are opened to allow the air in the environment to circulate between the outer tank 11 and the inner tank 12, and the air inlet 111 and the air outlet 112 are closed before brewing the next batch of beer to keep the state of the proofing tank consistent for each brewing and stabilize the brewing results each time.
[0020] The beneficial effects of the utility model are as follows: by circulating water from bottom to top on the lower cold box 22 and the upper cold box 21 for cooling, the gap between the lower cold box 22 and the upper cold box 21 is filled from bottom to top, and the inner tank 12 is covered by the strip-shaped lower cold box 22 and the upper cold box 21, a better cooling effect can be achieved. At the same time, due to the isolation of the air by the outer tank 11, the influence of external air on the cooling effect of the lower cold box 22 and the upper cold box 21 is avoided, and the cavity between the outer tank 11 and the inner tank 12 is kept in a relatively stable state.
