| 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. Because of different mean free of light and heavy
molecule, different matters have different moving
distance. Supposed putting 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.

Molecule distillation technology,
as an advanced international high and new separation technology, has
following advantages:
1. Operation temperate is
low (lower than
boiling point), with high vacuum (no load ≤1Pa), heating time is
short (several seconds) 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 separation is physical separation, preventing
separated matter from pollution, especially keeping original quality
of natural extraction.
4. The separation degree is higher than the traditional
distillation.
