product description:Molecular distillation is a special
distillation equipment that not only uses the difference in 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. Principle of
Molecular Distillation: 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 molecular distillation speed, so the thickness of the liquid
layer should be minimized 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 70~100ºC), and the form of the condensing surface
is reasonable and smooth, it is considered that the condensation
step can be completed instantly, so choose a reasonable condenser
The form is very important Product advantages: (1) For the
separation of high boiling point, heat sensitive and easily
oxidizable materials, molecular distillation provides the best
separation method. Because molecular distillation is operated at a
temperature far below the boiling point of the material, and the
residence time of the material is short; (2) Molecular distillation
can effectively remove substances in liquids such as organic
solvents, odors, etc., which is a very effective method for the
desolvation of liquids after solvent extraction; (3) Molecular
distillation can selectively distill the target product to remove
other impurities, and can separate more than two substances at the
same time through multi-stage separation; (4) The fractionation
process of molecular distillation is a physical process, so it can
protect the separated substances from pollution and damage. (5)
Pirani vacuum gauge imported from Japan is adopted, with high
measurement accuracy. Application scope: As a special distillation
equipment, molecular distillation 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. *Our Service Pre-Sale Service: Provide
