Different principle between molecular distillation and thin film distillation.

1.The molecular distillation instrument uses the size of the free path of molecules to achieve the purpose of separation, and sets a condensation surface at a certain position from the evaporation surface so that substances that can reach this surface can be separated;

2.Thin film distillation only make the evaporator process form a thin film on the evaporation surface to speed up evaporation.

3.Molecular distillation is a liquid-liquid separation technology that spreads the material through a scraper under vacuum to accelerate the evaporation of light components in the material. The evaporated gas encounters the condenser tube and is condensed and recovered.

4.Thin film distillation is a liquid-liquid separation technology that spreads the material through a scraper under vacuum to accelerate the evaporation of light components in the material. The evaporated water vapor enters the condensation recovery device for condensation and recovery under the pressure of vacuum, which can be called a high vacuum rotary evaporator.

5.Thin film distillation is considered a mild, safe, and effective separation method. It can be used to concentrate, purify or separate molecules with poor thermal stability and related organic mixtures and compounds with low volatility, high boiling point and high viscosity. In a high vacuum environment, molecular distillation has the characteristics of low distillation temperature, short heating time of materials, and fast separation speed. It is widely used in petrochemical industry, pharmaceutical chemical industry, essential oil purification, cosmetics and perfume purification and other fields.

6.Molecular distillation is considered the safest and most efficient separation method. It can be used to purify molecules with poor thermal stability and related compounds with low volatility and high boiling points. In a high vacuum environment, molecular distillation is characterized by low distillation temperature, short heating time of materials, and rapid separation. It is widely used in petrochemical industry, pharmaceutical chemical industry, essential oil purification, cosmetics and perfume purification and other fields.
