2 Stage Wiped Film Molecular Distillation System

Molecular Distillation is a special liquid-liquid separation technology, which is different from the traditional distillation by boiling point difference separation principle, but by different substances molecular movement of the average free path difference to achieve separation. Molecular distillation is considered as the safest mode of separation and to purify the thermally unstable molecules and related compounds with low volatility and elevated boiling point. The process distinguishes the short residence time in the zone of the molecular evaporator exposed to heat and low operating temperature due to vacuum in the space of distillation.

Wiped Film Evaporator(WFE) System :

Feed material is delivered into the main jacketed evaporator. With the consistent heat coming from jacket, a thin film in turbulent condition is formed, and then push forward spirally.

In the center an internal condenser provide a short path for vapor molecules traveling from the heated surface to the condenser cooling surface.

During the downward journey, lighter (lower boiling point) fractions of the liquid begin to vaporize, move to the internal condenser and condense which is then captured and separated  into the Distillate receiving flask. Heavier residue material (like chlorophyll, salts, sugars, heavy wax) do not evaporate, instead they travel the length of the main evaporator body and flows into the residue receiving flask.

Application :

  • Purification after extraction(Supercritical CO2, Butane, Hydrocarbon, Ethanol etc)
  • Vacuum Distillation of Terpenes, Terpenoids
  • Removal of Chorophyll, Phytosterols, Insecticide, Fat & Wax
  • Concentration of Bontanicals & Essential Oils
  • Oil Deodorization

Molecular distillation is used to distill high-value and high-purity extracts from essential oils of animals and plants, such as refined hemp oil, eaglewood, fish oil, traditional Chinese medicine, etc. Its extracts can be used as food additives, health products or medicinal raw materials.

Based on customer’s production needs, we can develop stainless steel molecular distillation solutions that is efficient and save customers cost to the greatest extent. We offer a wide range of high performance components, stable inlet and outlet modules and magnetic seals to eliminate secondary contamination during distillation. Sight glass and molecular pumps provide consistently low vacuum conditions with high visibility.

  • Modularized design for flexible options
  • Continuous feeding & collection modules design, saving labor cost and working time.
  • Fully jacketed design, wide applications for different materials 316L stainless steel, safe and reliable.
  • Sight glass and quick-connect design, easy to disassemble and clean
