A brief outline of the process is given below :
Dry spices/Herbs are cleaned of the adhered impurities and
other foreign material and powdered.
The powder is charged to the pre-heated extraction vessel
and the vessel is pressurized with CO2 from the storage tank. The CO2 is
passed through the extraction vessel resulting in the extraction of target
products (e.g. Oleoresin/Essential Oils). By depressurization of this mixture
into a separator vessel, gaseous CO2 is recovered, recycled, and fed back to
the storage tank.
The liquid or solid product is collected at the bottom
of a separator vessel and is withdrawn. Due to the earlier evaporation
of the CO2, this product is solvent-free. It is checked for quality,
standardized to our customer requirements and/or packed and labeled directly.
