Which types of molecular distillation equipment can be divided into

   With the development of science and technology, the development of molecular distillation equipment is also very rapid, and its application is more and more extensive. In order to make better use of molecular distillation equipment, it's necessary to learn aboutit before use. Now,let's introduce  the  molecular distillation equipment.
　　Molecular distillation, is also known as short path distillation.It is a relatively new liquid-liquid separation technology that is not yet widely used in industrial production.It can solve the problems that a large number of conventional distillation technologies cannot solve.
　　A complete set of molecular distillation equipment mainly includes:molecular evaporator、degassing system, feed system, heating system, cooling vacuum system and control system.The core of the molecular distillation equipment is the molecular evaporator,There are three main types:
　　(1)Falling film:it's  early forms. The structure is simple, but because of the thick liquid film and poor efficiency, it is rarely used in countries around the world today.
　　(2)Squeegee type:It formed thin liquid film , high separation efficiency, but more complex than falling film structure.
　　(3)Centrifugal:Film formed by centrifugal force, thin membrane, high evaporation efficiency, but complex structure, difficult vacuum sealing, high manufacturing cost of equipment.In order to improve the separation efficiency, it is  necessary to use multiple stages in series to achieve multi-stage separation of different substances.
