The change of CO2 flow rate has two effects on the supercritical co2 extraction machine. If the flow of CO2 is too large, the flow rate of CO2 in the extractor will increase, the residence time of CO2 will be shortened, and the contact time with the extract will decrease, which is not conducive to the improvement of extraction rate.
