Wiped Film Distillation Equipment 1L Air Sensitive Vacuum CBD Short
Wiped Film Distillation Description
As a special distillation equipment, the Wiped Film Distillation Equipment can achieve the purpose of purifying one component or more components by not only utilizing different boiling points of components in a mixture, but mainly relying on the difference of mean free path of molecular motion of different substances.
Working Principle
1. The molecules diffuse from the main body of the liquid phase to the evaporation surface: Generally, the diffusion velocity in the liquid phase is the main factor controlling the Wiped Film Distillation Equipment rate. Therefore, reduce the thickness of the liquid layer and enhance its flow.
2. The molecules freely evaporate on the surface of liquid layer: The evaporation rate increases with the increase of temperature, but the separation rate sometimes decreases with the increase of temperature. Hence, the economical and reasonable distillation temperature should be selected on the premise of the thermal stability of the processed material.
3. The molecules fly from the evaporation surface to the condensing surface: In this process, the steam molecules may collide with each other or with the gas molecules remaining between the two surfaces. The steam molecules are much heavier than air molecules, and most of them have the same movement direction, so their own collision has little influence on the flying direction and evaporation rate. The residual gas molecules are in the state of chaotic thermal motion between the two surfaces, so the number of residual gas molecules is the main factor influencing the flying direction and evaporation rate.
4. The molecules condense on the condensing surface: It is considered that the condensing step can be completed instantly as long as there is enough temperature difference between the hot and cold sides ( generally 70~100℃) and the form of the condensing surface is reasonable and smooth. So It is pretty essential to choose a reasonable condenser form.
