Short path molecular distillation (short-path distillation) is a new separation technique that addresses the problems that conventional distillation techniques cannot solve. It can achieve "liquid-liquid" separation at very low vacuum according to the mean free path difference of molecular motion under the temperature of much lower than the liquid boiling point; Mainly the use of scraper system forcing liquid film evaporation or distillation of a highly efficient evaporation, distillation equipment, deodorization, degassing reaction and supporting heating, cooling and other unit operations, can be widely used in food, fine chemicals , Electronic materials, plastic engineering and polymer (such as polyols, fatty acids, polyphenols, polyurethanes, epoxy resins, milk fat, GMS, flavors and fragrances, heavy oil and paraffin oil) purification and so on. The system can also be used to recover organic solvents from industrial effluents. Especially suitable for high boiling point, heat-sensitive, easily oxidized material separation and purification.
Working principle： ①Operating temperature is far below the boiling point of the material, thermal material handling, bio-acid fat, high boiling point, difficult to steam out of the material has great advantages ②Heating time is very short, ordinary distillation need to heat a few hours in the process, short-range distillation can be done on the tens of seconds, low carbon and environmentally friendly and conducive to maintaining the material activity ③Belong to the physical separation process, can keep the natural state of the material from pollution. Widely used in high value-added materials deodorization, bleaching and purification.
Products features： ①Evaporation tube body using G3.3 borosilicate glass: easy to observe the material under different conditions of pressure, temperature, flow and speed changes (such as material color, viscosity, film-forming effect, out of the critical point, etc.). Help to get the best process parameters and experimental data. ②Can achieve precise temperature control: the maximum temperature of the evaporation tube system can reach 200 ℃, the maximum temperature within the jacket up to 300 ℃; ③Transmission system: The magnetic coupling transmission, to ensure high-speed operation of the evaporation cylinder pressure limit system up to 0.001mbar ④Film self-cleaning roller or scraper system through the centrifugal force of the material into a film to improve the evaporation efficiency and reduce operating time; ⑤High cleanliness: the material in the separation process only contact with glass and PTFE composite material, no other pollution. ⑥Ease of maintenance: all flange design, easy disassembly. ⑦According to customer requirements, evaporation tube specifications Φ60 ∽ Φ300 optional.
