What's Short Path Distillation Apparatus? TOPTION Evaporator Supplier

Compared with traditional distillation method using the materials' boiling point difference to reach separation purpose. Molecular distillation is a special kind of liquid - liquid separation technology.
How molecular distillation achieve separation purpose?

1. Based on the mixture's each materials' different molecular motion mean free path. According to the principle of molecular motion mean free path, under ideal condition making the liquid mixture flowing through the heating plate to heat, light and heavy molecules will escape from liquid level, and enter into the gas phase.

2. Due to the light and heavy molecular free path is different, so after different material molecules escape from the liquid surface, their moving distance is different, if properly set up a cold condenser plate, then light molecules reach condensation plate be condensing exhaust, and heavy molecules can not reach condensation plate, the exhaust along with the mixture liquid.
Why molecular distillation is also named short path distillation?

1. According to this technical principle TOPTION engineers have design the falling film type, centrifugal type, wiped film type evaporators, in actual operation due to various limitations, it's difficult to achieve ideal molecular distillation separation, and there's a common characteristics of various vaporator: the evaporation surface and condensation surface distance is very short, the molecules escape from evaporation surface to condense into liquid, this path is very short so called short path distillator.

2. Rotating scraper type short path distillator separation process please check the drawing, materials charge at the top of the evaporator, through the material liquid distributor of the rotor, material is continuous evenly distribution in the heated surface, coating scraper blow materials into a very thin layer, as the turbulence of the liquid film.
3. During this process, light molecules escape from the heating surface, reach the condenser and be condensed as liquid, then along the condenser tube shed, through the evaporator discharge tube out, which is located at the bottom of evaporator. Residual liquid also is the heavier molecules are collected under the heating area of circular channels, again through the side of the discharge tube outflow.
A complete short path distillation apparatus set should include:

1. Short path evaporator.
2. Heating system.
3. Material charging system.
4. Cooling system.
5. Vacuum system.
6. Material collection unit, etc.
According to the nature of the separation material, reasonable selection and configuration of each unit, this is very critical for whole distillation system's performance.TOPTION strong engineers team is consist of chemical synthesis, technology and engineering, chemical machinery and other senior experts, mature synthetic technology and process engineering strong support for the chemical machinery manufacturing technology, complete sets of configuration is more pertinent and cut into the customer's requirements.
