What’s the Working Process of Extraction
Working process of extraction : a) The liquid CO2 in the CO2 storage tank C302 is sucked and pressurized by the pressurizing pump, and into the extraction heater E402 for preheating when reaches the supercritical pressure, and then into the extractor along the pipeline. At this moment, the CO2 is in a supercritical state and has strong dissolved ability; b) After the extraction pressure reaches the set pressure, the extraction regulator valve K01, the separator S201 regulator valve K02, and the separator S202 regulator valve K03 are all switched into the “automatic” operating mode. The CO2 that dissolves the active ingredients of the material depressurize passes through K01 into the heater E403; c) In the separator 1 heater E403, CO2 continues to be heated, and then into separator S201; d) In the separator S201, CO2 is heated and maintained by the hot water in its jacket. Due to factors such as pressure reduction, the dissolution rate of the active ingredient of the material is reduced...
