The steam enters the inner cavity of the connecting plate 14 through the distillation tube 4, and enters the inner cavity of the connecting plate 2 15 through the condenser tube 11. When passing through the condenser tube 11, the condenser tube 11 is a spiral structure with a large heat dissipation area, which can cool the steam for condensation and discharge it in the discharge pipe 5. At the same time, multiple groups of condensers 11 are arranged to further improve the condensation efficiency. The distillation component can be cooled by the cooling component. It should be noted that the fixed flange 13 is screwed on the tank body 2.

After the steam in the condenser 11 is cooled, it will condense into liquid and flow out through the discharge pipe 5.

[0022] See also Figure 3 When the above-mentioned distillation assembly is in use, if the material in the tank body 2 splashes, it is easy to enter the distillation tube 4.
