Introduction

Liquid-liquid separation technique carried out under molecular distillation conditions.The utility model has the advantages of low distillation temperature,high vacuum degree of the system,short heating time of the material,high degree of separation,and the like,and the separation process is irreversible and has no boiling bubbling phenomenon.It is especially suitable for the separation of high boiling point,heat sensitive and easily oxidized substances.It has been widely used in the extraction of active ingredients of vitamins and Chinese herbal medicines in the pharmaceutical industry,petrochemicals,food industry,cosmetics industry and agriculture.

Structural features

1.Place a condenser inside on the basis of the scraper evaporator.When the light mixture molecules move to a certain distance after the feed mixture is heated,the condenser is condensed into a liquid and separated,and the heavy material flows down the wall.Since the light material vapor phase is condensed internally,the vacuum pressure drop is small to maintain a high vacuum inside the device.

2.Extremely high vacuum:The special structural design of short-path distillation allows the operating pressure to reach an extremely low operating vacuum.The experimental scale of the equipment vacuum can reach 0.1Pa,even the industrial scale equipment can reach 1-5Pa.

3.The operating temperature is much lower than the boiling point of the material:Since the short-path distillation uses central condensation,the material flow cross-sectional area is equal to the evaporation surface,so that there is only a slight pressure drop between the evaporator and the condenser,that is,the vacuum degree at the end of the vacuum system.Almost close to the vacuum of the evaporator.Very low working pressures ensure extremely low distillation temperatures,so short-path distillation is currently the mildest distillation method.

4.Characteristics of molecular distillation equipment:The separation of the mixture is realized due to the different mean free path of different kinds of molecular escape liquid surface,and does not need to be completely boiled,so the actual evaporation temperature of the material in the evaporator is slightly lower than empty.The theoretical boiling point of the material under the conditions.This is essentially different from distillation.

5.Short-distance distillation has a short heating time:The film is designed by using a vertical scraper,and the residence time of the material on the heating wall is short.For other distillations,the heating time is generally longer (more than 30 minutes or even tens of hours).Short-range distillation is only a dozen seconds.Due to the strict distance requirement between the short-distance distillation heating wall and the condenser,the light molecules escaping from the liquid surface almost instantaneously reach the condensation surface,and the heating time of the vapor phase light molecules is negligible in this process.The possibility of thermal decomposition is minimized.

6.Excellent mass transfer and heat transfer efficiency:short-distance distillation adopts mechanical scraping membrane system,which is different from other film-forming unevenness defects such as falling film evaporator.The film thickness is uniform and the flow characteristics are excellent in short-range evaporator.The liquid surface and the heating surface have almost the same area,and the mass transfer and heat transfer efficiency are superior.
