Supercritical CO2 Extractor
Supercritical fluid extraction is a new extraction separation technology. It uses supercritical fluid, that is, fluid in a thermodynamic state with temperature higher than the critical temperature and pressure higher than the critical pressure, as an extractant. Specific components are extracted from liquids or solids for separation purposes.
The characteristics of supercritical fluid extraction are as follows: the extractant is a gas at atmospheric pressure and room temperature, and it is easy to separate from the raffinate phase and extraction group after extraction; Operating at low interference, especially suitable for the separation of natural substances; Pressure, temperature and the introduction of entraining agents can be adjusted to adjust the dissolution capacity of the overboundary fluid, and the extraction component can be introduced into the desired product by gradually densifying temperature and pressure.
