The molecular distillation is a special liquid-liquid separation technology, which is different from traditional distillation relying on the difference between boiling points. This is a kind of process of distilling and purifying the heat sensitive material or high boiling point material by making use of the difference of material molecular movement free path in high vacuum degree. The molecular distillation is mainly used in chemical, pharmaceutical, petrochemical, spices, plastics, oil and other fields.

Product Characteristics

  • High heating efficiency, rapid temperature rising
  • Heating by plate heating exchange, high heating speed
  • Sealed circulating heating, no contact with air
  • High circulating speed

Product Advantages

  1. High evaporation efficiency, less retention time, and minimum time delay.
  2. The molecular distillation is made from high borosilicate glass 3.3, stainless steel 316L and PTFE, which have excellent corrosion resistance.
  3. The main body of the molecular distillation is made of high borosilicate glass 3.3, allowing the whole process to be observed very clearly
  4. High-precision distillation barrel allows the liquid to form a complete and unified thin film on the heated surface. The smooth inner surface can avoid sticking and scaling.
  5. The German brand variable-frequency reduction motor can operate safely and reliably. The self-cooling fan can work continuously for a long time.
  6. The magnetic force transmission system can realize the sealing of whole machine. The transmission rod of the drive motor needn’t go through the sealing surface of the distiller. The whole system possesses a good sealing performance. The minimum vacuum pressure is up to 0.001mbar.
  7. The highest temperature of the system can reach 230℃/300℃. The accurate temperature control can be realized.
  8. Lower the oxidation speed of heating oil and lengthen the work life of heating oil, so that the change frequency of heating oil can be reduced.
  9. Much safer because of fully enclosing. It can be avoided that operators are hurt by high temperature.

Preheating system

Common volume: 2L, 5L, 10L, 20L

It’s used to heat the material to be separated, and suitable for the materials with high melting point and high viscosity.

2. Collection system

Rotary collection system
Rotary collection system

The distillate and residue receiving flasks are connected with three ports respectively through a three-direction discharger, which can receive more than two clear distillate and residue components under the non-venting vacuum system. The three-direction discharger offers a simple method to collect materials under different technology parameters.

3. Continuous collection system
