Distillation is a thermodynamic separation process, which uses the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condenses to separate the entire component. Divided by mode distillation method includes: simple distillation, equilibrium distillation, rectification, short path molecular distillation. Divided by operating pressure distillation method includes: normal pressure, pressurized, and reduced pressure.
Which type of distillation is most efficient? Short path molecular distillation equipment, which is a special liquid-liquid separation technology,and can be operated in extremely high vacuum.
1. Separation of high boiling point, heat sensitive and easy oxide materials.
2. Can extremely effectively remove substances in liquids such as organic solvents, odors, etc.
3. Can selectively evaporate the target product, remove other impurities, and can separate more than two substances at the same time through multi-stage separation.
4. Rose essence oil purification, ginger oil purification, angelica oil purifying & decoloration ( if use general water evaporation, after subcritical extraction, the color of angelica is black, but if use short path molecular distillation, the angelica color will keep bright & yellow).
