Wiped Film Distillation Equipment Cbd Oil Short Path For Laboratory

Principle of Wiped Film Distillation Equipment

1. Molecules diffuse from the main body of the liquid phase to the evaporation surface: Generally, the diffusion speed in the liquid phase is the main factor controlling the Wiped Film Distillation Equipment speed, so the thickness of the liquid layer should be reduced as much as possible and the flow of the liquid layer should be strengthened.

2. Free evaporation of molecules on the surface of the liquid layer: the evaporation rate increases with the increase of temperature, but the separation factor sometimes decreases with the increase of temperature, so the thermal stability of the processed material should be the premise , Choose an economical and reasonable distillation temperature.

3. Molecules fly from the evaporation surface to the condensation surface: When the vapor molecules fly from the evaporation surface to the condensation surface, they may collide with each other, or they may collide with air molecules remaining between the two surfaces. Since evaporation molecules are much heavier than air molecules, and most of them have the same direction of motion, their collisions have little effect on the direction of flight and the speed of evaporation. The residual gas molecules are in chaotic thermal motion between the two sides, so the number of residual gas molecules is the main factor that affects the direction of flight and the evaporation speed.

4. Molecules condense on the condensing surface: 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, it is considered that the condensation step can be completed in an instant, so choose a reasonable condenser The form is very important

Wiped Film Distillation Equipment Description

Wiped Film Distillation Equipment is a special distillation equipment that not only uses the difference in the boiling points of the components in the mixture, but also uses the difference in the mean free path of molecular motion of different substances to achieve separation to achieve the purification of a certain component or several components. purpose.

Product advantages

(1) For the separation of high boiling point, heat sensitive and easily oxidizable materials, Wiped Film Distillation Equipment provides the best separation method. Because Wiped Film Distillation Equipment is operated at a temperature far below the boiling point of the material, and the residence time of the material is short;

(2) Wiped Film Distillation Equipment can very effectively remove substances in liquids such as organic solvents, odors, etc., which is a very effective method for the removal of liquids after solvent extraction;

(3) Wiped Film Distillation Equipment can selectively evaporate the target product and remove other impurities. Through multi-stage separation, more than two substances can be separated at the same time;

(4) The fractionation process of Wiped Film Distillation Equipment is a physical process, so the separated substances can be well protected from pollution and infringement.

(5) Pirani vacuum gauge imported from Japan is adopted, with high measurement accuracy.

Application Scope

As a special distillation equipment, Wiped Film Distillation Equipment uses the principles of short-path distillation and average molecular free path to separate compounds, which greatly reduces the difficulty of purification. It is widely used in the food industry, fine chemical industry, pharmaceutical industry, and so on. Such as: the production of monoethylene glycol, the refinement of fish oil, the purification of polymer intermediates, the purification of aromatic oils, the purification of cannabinoids and so on.
