Feb 26, 2020 The short path distillation process employs a setup that uses the same principles, just without the wiper system to distribute the extraction material. Instead, a heated flask is where the extraction material is fed. Gradually, increased heat is applied to the extract material in the feed flask. A vacuum is also applied to assist in drawing the ...

Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids.

Oct 08, 2019 Molecular distillation uses a very high vacuum system which effectively reduces the pressure in the system to zero and allows compounds to essentially vaporize instantaneously. [1] The distillate proceeds in a continuous-feed fashion, and the rate of distillation depends on flow velocity and surface area of the heating and cooling blocks. ...
