Supercritical extraction technology is the latest subject in modern chemical separation, and it is an advanced separation technology rising in the world. The so-called supercritical fluid refers to the fluid whose thermodynamic state is above the critical point (Pc, Tc). The critical point is the state point where the gas-liquid interface just disappears. The supercritical fluid has very unique physical and chemical properties, its density is close to the liquid, its viscosity is close to the gas, and its diffusion coefficient is large, its viscosity is small, and its dielectric constant is large, so that its separation effect is good Solvent. Supercritical extraction means that under high pressure and proper temperature, the solvent contacts with the extract in the extraction cylinder, the solute diffuses into the solvent, and then changes the operating conditions in the separator to separate the solute to achieve the purpose of separation.

Since CO2 medium is selected as supercritical extractant in supercritical unit, it has the following characteristics:

1、Wide operation range, easy to adjust.

2、It has good selectivity. It can extract the required components by controlling the pressure and temperature.

3、Operating temperature is low, and extraction is carried out near room temperature, which is particularly suitable for heat sensitive components. The possibility of oxygen oxidation and light reaction is excluded in the extraction process, and the extract can maintain its natural flavor.

4、From extraction to separation, the CO2 after extraction will not remain on the extract.

5、CO2 is nontoxic, tasteless, nonflammable, cheap and easy to obtain, and can be recycled.

6、The extraction speed is fast.
