supercritical CO2 extraction equipment

. Supercritical CO2 extraction technology is the latest subject in modern chemical separation and it is an advanced separation technology rising in the world. The so-called supercritical fluid is the thermodynamic state liquid which is above the critical point and the critical point is the point at which the gas-liquid interface just disappears. The supercritical fluid has very unique physical and chemical properties, its density close to the liquid, viscosity close to the gas. The big diffusion coefficient, low viscosity, big dielectric constant and other characteristics make its separation effect better, so it is a good solvent. Supercritical extraction, namely, under high pressure and appropriate temperature, solvent contact with the material in the extraction vessel, the solute diffuses into the solvent, and then in the separator change the operating conditions to separate out the dissolved substance in order to achieve separation purposes.


The Essence Extraction Machine is used for the extraction of material (solid or liquid) under high pressure and suitable temperature extraction. Changing conditions in the separation kettle, the dissolved substances will resolve in order to achieve the purpose of separation. The supercritical CO2 extraction is especially suitable for extraction of fat-soluble and heat sensitive substances with high boiling point. Take CO2 as the solvent to make extraction and purification upon a lot of products such as biological products, foodstuff and medicines.
