To solve this problem, two circulation systems are generally used in the prior art, as shown in fig. 1: comprises a primary water circulation system and a process water circulation system, wherein the primary water circulation system and the process water circulation system are isolated by a plate heat exchanger. The specific principle is as follows: in the process water circulating system, one part of ice tank water at 50 ℃ is used as process water, the other part of the ice tank water enters a plate heat exchanger for heat exchange, and the ice tank water is cooled to 28 ℃ and then is pumped to the ice tank again for cooling wine steam. In the primary water circulation system, two situations are adopted: one is that when the temperature of the system is lower, the primary circulating water can be cooled to the required temperature (24 ℃) only by the cooling tower, and then the cooling water output by the cooling tower directly enters the plate heat exchanger under the condition, the temperature is raised to 48 ℃ after heat exchange, and the cooling water enters the cooling tower again for circulation; and the other is that when the temperature and the humidity rise, the refrigerating machine needs to be started for auxiliary cooling, the cooling tower cools the primary circulating water to 30 ℃, the primary circulating water enters the evaporator of the refrigerating machine and is cooled to 24 ℃ again, then the primary circulating water is pumped to the plate heat exchanger, the temperature rises to 48 ℃ after heat exchange, and the primary circulating water enters the cooling tower again for circulation.
