Molecular Distillation Equipment
Basic principle
Molecular distillation is a special liquid-liquid separation technology, which is different from the separation principle of traditional distillation depending on
boiling point difference. It is depending on the difference of molecular mean free path to separate different matters. Here, molecular mean free path (λ) refers to
the path between a molecule strikes two times.
When the mixture of liquid flows along the heating board and is heated, light and heavy molecule will leave the surface of liquid and enter the vapor phase. Light and
When the mixture of liquid flows along the heating board and is heated, light and heavy molecule will leave the surface of liquid and enter the vapor phase. Light and
heavy molecule will have different moving distance when they are in vapor phase because they have different mean free path. Supposing that we put a condensation board
at the proper position, light molecule can reach the board and will be condensed, then be discharged along the condensation board; while the heavy molecule will not
reach the board and be discharged along the heating board. Therefore, the objective of separation has been reached.

Product Advantage
Molecule distillation technology, as an advanced international high and new separation technology, has following advantages:
1.Operation temperature is low (lower than boiling point), with high vacuum (no load ≤1Pa), heating time is short (several seconds) thus no thermal decomposition
1.Operation temperature is low (lower than boiling point), with high vacuum (no load ≤1Pa), heating time is short (several seconds) thus no thermal decomposition
occurs and the efficiency of separation is high. Specially, it is adapted to separation of high boiling point, heat-sensitive and easy oxidized matters.
2.Removing low molecule matter (odor removal), heavy molecule matter (decolor) and impurities of mixture.
3.The course of molecular distillation is a physical separation, preventing separated matter from pollution, especially keeping original quality of natural
