Supercritical fluid extraction of liquids and solids (SFE)
|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.|
The system is assembled on the basis of pressure chambers 5, 50, 150, 300, 500 and 1000 liters.
