The composition and working principle of molecular distillation apparatus in laboratory are introduced as follows:
1. Composition of Molecular Distillation Instrument in Laboratory:
A complete set of molecular distillation apparatus mainly includes: molecular evaporator, degassing system, feed system, heating system, cooling vacuum system and control system.
2. Working principle of molecular distillation apparatus in laboratory:
Molecular distillation/short-range distillation is a relatively new separation technology, which can solve many problems that conventional distillation technology can not solve. Molecular distillation is a special liquid-liquid separation technology, which can operate in extremely high vacuum. According to the difference of the average free path of molecular movement, it can separate the liquid at a temperature far below its boiling point, especially for the separation of high boiling point, thermal sensitivity and oxidizable systems. Short-range distillation has the characteristics of lower distillation temperature, lower distillation pressure, shorter heating time and higher separation degree, so it can greatly reduce the difficulty of separation technology of high boiling point materials and heat-sensitive materials, and protect the characteristics and quality of heat-sensitive materials. The molecular distillation equipment is especially used for the extraction of natural health products and so on. It can get rid of the restraint of chemical treatment methods and truly maintain the pure natural characteristics.
