The pressure in the evaporator is almost equal to that in the condenser, and the pressure drop is small. Its internal structure is simple, without complex pipes and valves, and the smooth inner surface of the glass makes cleaning and maintenance very convenient.
Short path molecular distillation is a new technique that address the problems that conventional distillation techniques cannot solve . It can achieve liquid to liquid separation at very low vacuum degree according to the mean free path difference of molecular motion under the temperature of much lower than the liquid boiling point . Mainly the use of wiped system forcing liquid film evaporation or distillation of a highly efficient evaporation, distillation equipment , deodorization , degassing reaction and supporting heating , cooling and other unit operations , can be widely used in food , fine chemicals , electronic materials , plastic engineering and polymer purification , etc . The system also can be used to recover organic solvents from industrial effluents , especially for high boiling point , heat-sensitive , easily oxidized material separation and purification .
