What is distillation
Distillation is a thermodynamic separation process that utilizes different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire component. The operation consists of evaporation and condensation.
Compared with other separation methods, such as extraction, adsorption, and so on, it has the advantage that it does not require the use of solvents other than the system components, thereby ensuring that no new impurities are introduced.
What is short path distillation
Short path distillation is an effective separation method that is used to separate liquid and liquid, which is much more effective than traditional separation method. Short path distillation is a special separation method that can operate under extremely high vacuum.
It separates liquid and liquid through the difference of substances’ boiling points, and is suitable for high boiling point, heat-sensitive, easy-oxide substances. Short path distillation’s temperature is lower than the boiling point of materials. What’s more, it has a low evaporating pressure, short heating time, and high separation efficiency. So short path distillation can protect the specialty of substances and also save energy. Short path distillation is specially used for the extraction of natural health care products, which can get rid of chemical reaction to keep the nature of products.
