Molecular Distillation System for Plant Extracts

Product Overview:

A molecular distillation system capable of achieving 0.01 μm-level separation precision under low-temperature, high-vacuum conditions. Utilizing the principles of short-path evaporation and differences in molecular mean free paths, it effectively separates volatile and heat-sensitive components from plant extracts. It is specifically designed for the purification of high-value plant essential oils and bioactive small molecules, as well as for the standardized processing of cosmetic and pharmaceutical raw materials.

Key Advantages and Selling Points:

Ultra-high precision separation: Achieves a separation precision of 0.01 μm, capable of distinguishing components with minimal molecular weight differences to yield high-purity monomers and products within specific molecular weight ranges—delivering quality far superior to traditional distillation.

Low-temperature activity preservation: Evaporation temperatures can be as low as 60–80°C—well below atmospheric boiling points—preventing damage to heat-sensitive active ingredients and retaining over 95% of their biological activity.

Minimal thermal exposure: Materials remain on the heating surface for only seconds to tens of seconds, significantly reducing the risk of thermal decomposition and polymerization; this is particularly ideal for volatile oils and aromatic components.

Purely physical process: No chemical solvents are added throughout the process, ensuring residue-free products that meet the stringent purity standards for cosmetic and pharmaceutical raw materials—offering a safe, eco-friendly solution.

Intelligent integrated control: Features high-precision vacuum regulation and temperature control systems, ensuring excellent batch stability and reproducibility, ease of operation, and suitability for continuous production.

Primary Applications:

Fractional distillation and purification of high-value-added plant essential oils (e.g., rose, lavender, peppermint)

Separation and enrichment of small-molecule natural active compounds (e.g., Vitamin E, phytosterols, squalene)

Standardized decolorization and deodorization of cosmetic active ingredients and pharmaceutical intermediates

Concentration and refining of heat-sensitive natural pigments
