Guided by the top guide plate, the steam enters the interior of the distillation tank through the top vent and transmission pipes. Inside the distillation tank, the same heating method is used to further evaporate the liquefied material. After distillation through the two distillation tanks, the material vapor is transmitted through the transmission pipes into the condenser tube. After external cooling water is injected into the condenser tank through the circulation pipe, the steam flowing inside the condenser tube undergoes efficient cooling and liquefaction. Finally, the control valve on the side opens, allowing the liquefied material to be discharged and collected through the discharge pipe. The negative pressure distillation structure makes distillation more efficient and energy-saving. At the same time, the combination of multi-distillation structure makes the distillation process more comprehensive and thorough. The automated control structure makes it more convenient and efficient to use. Attached Figure Description
