[0021] Please refer to Figure 2 The surface of the mixing tank 7 is fixedly connected with the box body 1 through a support rod. Stirring teeth 22 are fixedly sleeved on the surface of the stirring rod 14. By setting the stirring teeth 22, the solution can be stirred and mixed more evenly and thoroughly, improving the mixing efficiency;
[0022] Please refer to Figure 1 On the left side of the front side of the box body 1, a box door 9 is connected by a sealing hinge. By setting the box door 9, it is convenient to open the front side of the box body 1 to take out the storage shell 18 after drying.

After the solution cooling is completed, the crystallizer 17 and the heat exchange module 20 stop working and control the vacuum pump 8 and the electric heater 19 to work. The vacuum pump 8 pumps out the air in the box body 1 to form a vacuum environment, and then the electric heater 19 heats the crystallized solution in the storage shell 18. In this way, by increasing the temperature and reducing the pressure, the ice crystal support is changed from a solid state to a gaseous state, and the moisture sublimes into a gas and is discharged. At this time, control the exhaust fan 3 to work to pump the gas in the box body 1 into the purification box 2, and after being adsorbed and purified by the activated carbon filter screen 21, it is discharged into the air. In this way, the discharged odor gas can be purified to avoid polluting the working environment.
