CO2 extraction

Supercritical fluid extraction of liquids and solids (SFE)

CO2 extraction machine Nembus


The Nembus extractor series is supercritical and subcritical extraction machine of raw materials. CO2 effectively preserves the chemical composition of extracts and, compared to an organic solvent, is a pure and stable fluid. In addition, it is non-flammable, non-toxic and leaves no residue in the product. The gas used for extraction makes it possible to obtain substances in any form: silicone, pasty, liquid and dry.

carbon dioxide extraction types
1. Supercritical. Being a fluid, CO2 has the properties of a non-polar solvent: it extracts non-polar substances in whole or in part. If another solvent is added to the gas, the extraction of polar substances becomes available. This method is characterized by high profitability and low energy consumption.
2. Subcritical. In the absence of heating, CO2 behaves similarly to a liquid. In the extraction process, you can get a maximum of biologically active substances.
As a result, the extract retains its healing properties.
types of extracted products
1. Selective. Biologically active components are removed without heating the raw material. They contain volatile solutes. Selective extracts are partially similar to steam distillation products, but may have a completely different composition.
2. Whole. Extracts with volatile and non-volatile soluble components in the composition. Such oils contain paraffins, heavy resins and pigments.
