[0034] Specifically, the milk liquid is added to the concentration tank 1, and the milk liquid inside the concentration tank 1 is heated after the heating pipe 8 is started. In the heating process, the water in the milk liquid evaporates, and the milk liquid is concentrated. At the same time, the evaporated water and part of the milk liquid enter the rectifying column 5, and the evaporated milk liquid and a small amount of water return to avoid waste of the milk liquid. A large amount of water vapor enters the condenser 6 to be liquefied again and flows into the liquid tank 7 to be collected. During the concentration process, the servo motor 10 is started to drive the main shaft 901 to rotate clockwise, thereby driving the stirring paddle 902 to rotate clockwise synchronously to stir the milk liquid, which is beneficial to the evaporation of excess water in the milk liquid.
