Wiped Film Stills


    This advanced technology is based on the principle of scraping film under a high vacuum and at high temperature.

    Under these conditions, the difference between the boiling temperatures of the various molecules making up the product will allow them to be distilled, separated, concentrated or selectively fractionated.

    These particular conditions always preserve the distilled product without altering the integrity of its molecules.

    The treated matrices are products with high molecular weight or high viscosity. They can be oils, fats or waxes of vegetable or animal origin. Or synthetic oils or specialty chemicals or waxes. In cbd industry, could guarantee >80% high purity cbd distillate.

    Combined with high-pressure catalytic equipment, it can produce HHC, delta8, etc. to increase the added value of products.


    TOPTION industrial molecular distillation service offers the advantage of processing oils, fats, waxes, and more generally, oleochemicals and speciality products without altering the base matrix.

    The main operations of molecular distillation are deodorization, decolourisation, decontamination of undesirable substances (pesticides, molecular contaminants), as well as fractionation and concentration of high added value active ingredients for the cosmetic, pharmaceutical and nutraceutical sectors.

  • The chemical and food speciality industries are also beneficiaries of this solution for the treatment and revaluation of fats.

    1. Toxicity: Avoids the problem of toxicity of solvents used as the separating agent.

    2. Thermal stability: Minimizes losses due to thermal decomposition.

    3. Continuous process: It can be used in a continuous feed process to harvest distillate without having to break the vacuum.

    4. Stability: The vacuum allows oils to be processed at minimal temperatures, reducing the risk of oxidative damage.

    5. Purity: Separating the oil’s components by weight allows contaminants to be reduced far below industry standards.

    6. Concentration: Weight grouping allows the processor to concentrate fatty acids.

    7. Short residence time: This process has a short residence time of the feed liquid.

    8. It works at a significantly lowered temperature due to high vacuum capability

    9. It has optimal efficiency in mass and heat transfer.

    10. It is suitable for processing high-value products.
