Supercritical fluids are a state of matter between gas and liquid that is neither gaseous nor liquid, and can only exist when their temperature and pressure exceed critical points. Supercritical fluids are denser and more liquid-like, and have a viscosity closer to that of gases. Therefore, the supercritical fluid is an ideal extracting agent. The solvent strength of the supercritical fluid depends on the temperature and pressure of extraction. By utilizing the characteristics, different components in a sample can be extracted sequentially according to the solubility in the fluid by only changing the pressure and the temperature of the extractant fluid, substances with weak polarity are extracted first under low pressure, and substances with larger polarity and large molecular weight and basic properties are extracted along with the increase of the pressure, so that the supercritical extraction is carried out under the program pressure to obtain different extracted components, and the separation effect can be realized.
With the development of technology, supercritical fluids have been widely used in pharmaceutical applications, such as purification of enzymes, vitamins, etc., extraction of pharmaceutical components in animals and plants, concentration and purification of pharmaceutical raw materials, separation of sugars and proteins, and separation and purification of desolvated fat mixtures.

The extraction of polar and medium polar components by supercritical fluid extraction can overcome sample loss and environmental pollution caused by solvent recovery in the traditional extraction method, is especially suitable for extracting heat-sensitive volatile compounds, and can change the extraction range of a mixture with larger polarity by adding polar entrainers such as ethanol, methanol and the like so as to improve the extraction rate. At present, the available medical resources at home and abroad by adopting the supercritical carbon dioxide fluid extraction technology comprise angelica, schisandra, artemisia annua, common andrographis herb, rhubarb, common cnidium fruit, hemp and the like.
In the prior art, the supercritical extraction pharmaceutical technology generally adopts carbon dioxide in a supercritical state as a solvent, and although the supercritical carbon dioxide fluid extraction has the advantages of pure natural green pollution-free extraction, strong extraction capability, high extraction rate, quick extraction time, short production period and the like, after actual extraction, when the separation is carried out in the separating tank by changing the temperature and the pressure, the phenomenon of incomplete separation exists, that is, when the carbon dioxide is released, separated and recovered, some effective substances extracted to some extent are also included, so that not only is the extraction rate difficult to exert to the maximum and the waste of the effective substances is caused, meanwhile, effective substances enter circulation to influence the subsequent extraction efficiency, and in order to avoid the phenomenon, the separated carbon dioxide needs to be purified to remove the effective substances of the carbon dioxide, therefore, we propose a fluid diversion adsorption device based on supercritical extraction pharmaceutical technology.
