[0021] Please see Figure 1-3 A low-temperature vacuum distillation and concentration apparatus includes a distillation tank 100, which is connected to a vacuum device. A feed pipe 110 is fixedly connected to the left side of the distillation tank 100, and a first solenoid valve 120 is fixedly installed on the left side of the feed pipe 110. An outlet pipe 130 is provided on the lower side of the distillation tank 100. A condenser 140 is fixedly connected to the right side of the distillation tank 100, and a heating device 150 is fixedly connected to the lower side of the condenser 140. A dispersion device 200 is connected to the upper side of the distillation tank 100, and a discharge pipe 170 and a collection device 300 are connected to the lower side of the distillation tank 100. The raw material enters the distillation tank through the feed pipe 110. The raw material enters the distillation tank 100 and is heated by the heating device 150. Then, the gas is discharged from the gas outlet pipe 130 and then the liquid is extracted by the condenser 140. The remaining raw material is discharged from the discharge pipe 170. During this process, the dispersion device 200 mixes the raw material, thereby ensuring that the raw material is fully heated. Then, the dispersion device 200 introduces clean water, disperses the clean water, and cleans the inside of the distillation tank 100. Then, the cleaning water is collected by the collection device 300. An observation window 101 is fixedly connected to the front of the distillation tank 100, which facilitates the observation of the distillation tank 100 by the staff.

[0022] The dispersing device 200 includes a rotating tube 210 and a motor 220. The upper side of the rotating tube 210 is rotatably connected to the distillation tank 100.

The rotation of the mixing tube 230 then mixes the raw materials, improving the efficiency of the raw material distillation and concentration. Simultaneously, the external water source is connected through the mixing tube. The mixing pipe 230 and the rotating pipe 210 spray water to clean the distillation tank 100. By setting up a dispersion device 200, the raw materials can be mixed as needed by rotating the mixing pipe 230, improving the efficiency of raw material distillation and concentration.

An auxiliary plate 211 is fixedly connected to the lower side of the rotating pipe 210, and a cleaning brush 212 is fixedly connected to the lower side of the auxiliary plate 211. The auxiliary plate 211 and the cleaning brush 212 facilitate the cleaning of the distillation tank 100 according to the requirements of the mixing pipe 230 and the rotating pipe 210.
