Short path molecular distillation (short-path distillation) is a new separation technique that addresses the problems that conventional distillation techniques cannot solve. It can achieve”liquid-liquid” separation at very low vacuum 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 scraper 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 (such as polyols,fatty acids, polyphenols, polyurethanes, epoxy resins, milk fat, GMS, flavors and fragrances,heavy oil and paraffin oil) purification and so on. The system can also be used to recover organic solvents from industrial effluents.Especially suitable for high boiling point, heat-sensitive, easily oxidized material separation and purification.
- Operating temperature is far below the boiling point of the material, thermal material handling, bio-acid fat, high boiling ponit,difficult to steam out of the material has great advantages;
- Heating time is very short,ordinary distillation need to heat a few hours in the process; short-range distillation can be done on the tens of seconds, low carbon and environmentally friendly and conducive to maintaining the material activity;
- Belong to the physical separation process, can keep the natural state of the material from pollution;
- Widely used in high value-added materials deodorization, bleaching and purification.
