Molecular Distillation Technology Services
Molecular distillation, is a technique for efficient separation and purification under high vacuum conditions. The operation of molecular distillation must meet three necessary conditions: the average free range of molecular motion of the light and heavy components must be different; the distance between the evaporating and condensing surfaces must be smaller than the average free range of molecular motion of the light components; and there must be a very high vacuum level. Molecular distillation has the advantages that other separation techniques cannot match: low operating temperature, high vacuum, short heating time, high separation efficiency, especially suitable for the separation of high boiling point, heat-sensitive, easy to oxidize substances; can effectively remove low molecular substances, heavy molecular substances and impurities in the mixture; separation process is a physical separation process, can well protect the separated substances from contamination, especially to maintain the original quality of natural extract The degree of separation is higher than that of traditional distillation and common membrane evaporator.
Applications of Molecular Distillation
- Suitable for the separation of liquid mixtures with large differences in molecular masses between different components.
- Separation of materials with similar molecular masses but different properties, such as the separation of substances with a large difference in boiling point and similar molecular masses.
- Heat-sensitive, easy to oxidize (easy to polymerize), the separation of high boiling point substances.
- Separation and purification of liquid or liquid semi-solids.
- Separation of volatile flavor substances from oils and fats, such as the separation of volatile aroma substances in flavored oils.
Our Services
BOC Sciences offers molecular distillation services with the advantages of low heating temperature, short heating time and high degree of separation, suitable for the separation of high boiling point and heat sensitive substances, such as oil and fat refining processes, extraction of natural products, decontamination, decolorization, etc. In addition, we also provide solutions such as process optimization of molecular distillation to help our customers quickly perform extraction and refinement of natural products.
Extraction of natural products
Extraction of natural vitamin E and phytosterols from vegetable oil seeds; extraction of natural carotenoids from tomatoes, egg yolks and carrots, etc.; extraction of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from fish oil; extraction of 2-phenylethyl alcohol from rose oil, neroli oil, etc.
Decolorization and impurity removal services
Molecular distillation technology can effectively remove impurities and colors from products, resulting in higher purity and better color. For example, it is applied to the refinement of fatty acids and their derivatives, fatty alcohols and their derivatives, etc., such as the purification of monoglycerides of stearic acid.
Molecular distillation process optimization
- By adjusting the ratio of recombinant and light components, distillation pressure, distillation temperature and other conditions, thus improving the extraction efficiency of natural products.
- Molecular distillation steps.
- Formation of a liquid film on the heated surface of the material.
- Free evaporation of molecules on the surface of the liquid film.
- Movement of molecules from the heating surface to the condensing surface.
- capture of light molecules on the condensing surface and return of heavy molecules to the liquid film of the material.
- Collection of distillates and residues.
