How To Choose Short Path Distillation System? TOPTION Professional Engineer Talk
Multi-stage thin film and short path evaporator connect together in series, through continuous multistage
distillation, can realize the separation of multicomponent complex mixture.
Need many times demonstrated experiment before model selection, shouldn't simple to assemble, so
professional type selection, installation and after-sales service is very important.
Let's check commonly used single-stage short path distillation unit processes as below:
1. Laboratory short path distillation system:
2. Continuous discharge type short path distillation system:
3. Batch type industry short path distillation system
Why so many research love choose short path distillation process?
1. Material be heated in short time
Rotating scraper push the material on the heating surface and the material liquid spiraling continuously
moves down and escape from the heating surface, the material which is separated escape from the heating
surface was quickly collected by condenser cooling, this method has to minimize the contact time of material
and heating surface.
Successfully eliminates the thermal decomposition, polymerization, or metamorphic.
2. Low evaporation temperature
Compared with conventional distillation, short path distillation apparatus through material liquid distributor
and rotating scraper to make material be uniform distribution on the heating surface, reducing the pressure
difference which is generated on material static liquid surface.
Heating surface and condensation surface distance is short, light molecules escape from the heating surface
then quickly condensation, reducing the pressure drop during gas transfer, which is more likely to achieve
low evaporation pressure.
As long as the light molecular movement free path is greater than the distance from the evaporation surface
to the condensation surface, then material can be separated, and material don't need be heated to boiling
point, thus the distillation temperature was much lower than the conventional distillation method.
3. Self-cleaning heating surface
Rotating scraper sliding in the heating surface, the liquid film constant agitation and updates, to prevent the
material in the heating surface bubble, scraping wall scaling, etc.
So short path distillation system can successfully be applied to the material consentration and
separation which is easily bubble, in the heating surface fouling in conventional distillation.
4. High efficiency evaporation, strong adaptability, easy operation
Rotating scraper makes the material be uniform distributed on heating surface as a film, the liquid film always
maintain high turbulence state, which accelerates the heat transfer to reduce the heat loss.
Simple structure, convenient cleaning, freedom of start-up and shut-down, suitable for many varieties, discontinuous
small chemical production.
What's your benefits from the short path distillation system?
Due to the above characteristics of short path distillation, can eliminate thermal decomposition, polymerization
or metamorphic, so this technology has already become the most moderate separation purpose distillation
method, particularly suitable for concentration, purification and separation of high molecular weight, high boiling
point, high viscosity material and poor thermal stability of organic compounds.
This short path distillation technology used in the extraction of natural health products, can get rid of the bondage
of chemical processing method, really keep the characteristics of the natural, is seen as a protector of natural
What's application of short path distillation technology?
1. Thermal separation of heat sensitive chemical compounds.
2. The purification of organic synthetic material.
3. The separation of effective components from the biological extracting solution.
4. The recycling of industrial waste.
5. Remove toxic substances in the food industry.
6. The organic compounds' decoloring, and eliminate the unusual smell.
7. High precision to remove residual solvent in chemical compound.
