What is the key of Supercritical fluid extraction?

Author:


Supercritical fluid extraction, especially supercritical multi-fluid gradually selective extraction, recombinant extraction, distillation extraction of new technology, including compound traditional Chinese medicine, new preparation processing of ethnic medicines, tobacco deep processing, tea deep processing, marine biological resources, supercritical for supercritical fluid, is a non-gaseous and non-liquid state of matter between gas and liquid, this substance can only exist when its temperature and pressure exceed the critical point.

Supercritical fluid extraction, especially supercritical multi-fluid gradually selective extraction, recombinant extraction, distillation extraction of new technology, including compound traditional Chinese medicine, new preparation processing of ethnic medicines, tobacco deep processing, tea deep processing, marine biological resources, supercritical for supercritical fluid, is a non-gaseous and non-liquid state of matter between gas and liquid, this substance can only exist when its temperature and pressure exceed the critical point.

 

The principle of the separation process of supercritical extraction equipment extraction (SFE) is to apply the relationship between the dissolution of the supercritical fluid and its density, that is, the influence of pressure and temperature on the dissolution of the supercritical fluid is stopped. In the supercritical state, the supercritical extraction equipment contacts the supercritical fluid with the substance to be separated, so that it selectively extracts the components of polarity, boiling point and molecular weight.

Supercritical fluid density is large, similar to liquid, and its viscosity is closer to gas, so supercritical fluid is a very ambitious extractant, extraction equipment extraction generally use supercritical water reaction and supercritical carbon dioxide repercussion, water and carbon dioxide is no environmental pollution medium, supercritical fluid repercussion engineering is suitable for the 21st century emerging industry revival of green industry application technology, carbon dioxide gas low price, high purity, easy to manufacture, can be recycled in consumption application, effectively reduce costs.
