Principle of Wiped Film Distillation
Stainless steel wiped film molecular distillation, also known as short-path distillation, is a continuous distillation process carried out under high vacuum. The molecular distillation process is more precisely the process of molecular evaporation.
Molecular distillation is different from traditional distillation based on the separation principle of material boiling point difference. Molecular distillation is a special liquid-liquid separation technology that uses the principle of molecular free path to separate materials containing different substances.
Molecular distillation has the characteristics of short heating time, low distillation temperature and high degree of separation.
Molecular distillation is suitable for materials with high molecular weight, high boiling point, high viscosity, heat sensitivity and biological activity.
What is Stainless Steel Wiped Film Distillation Equipment?
A complete set of molecular distillation equipment mainly includes: molecular evaporator, degassing system, feeding system, heating system, cooling vacuum system and control system. The molecular evaporator is the core part of the molecular distillation device.
Wiped-film molecular distillation equipment has high separation efficiency and has been widely used in fine chemicals, medicine, fragrances, essential oils, food and other industries. It has advanced technology, less risk of thermal decomposition, high productivity, and easy maintenance.
Features of Stainless Steel Wiped Film Distillation
Large heat transfer coefficient and high evaporation efficiency;
Stainless steel materials are safer, stronger, and not easily damaged;
Larger production scale and higher efficiency.
Advantages of Stainless Steel Wiped Film Distillation
Compared with conventional distillation, molecular distillation has the following advantages:
The operating temperature is low, which greatly saves energy consumption. Molecular distillation is operated far from the boiling point, so the energy consumption of the product is small.
The distillation pressure is low, and it is operated under high vacuum.
The heating time is short, reducing the heat damage of heat-sensitive substances. The decomposition or polymerization of substances is largely avoided.
Stainless steel molecular distillation separation degree and high product yield.
A complete set of molecular distillation equipment mainly includes: molecular evaporator, degassing system, feeding system, heating system, cooling vacuum system and control system.
