Molecular distillation is a special kind of liquid-liquid separation technology, it is different from traditional distillation on the boiling point is poor separation principle this is a kind of use of different materials under high vacuum molecular motion free path difference, the heat sensitive material or is the separation of high boiling point distillation and purification process of this equipment is mainly used in the chemical pharmaceutical biological incense material plant extracts and oils industry such as vacuum concentration, extraction, separation, desolventizing, decoloring process etc
