What is the key of Supercritical fluid extraction?

Author:

The industrialization of extraction technology of supercritical fluid extraction is mainly simple supercritical CO2 distance extraction, and the materials after processing small extraction equipment are also mainly obtained from solid plants, most of which are crude extraction mixtures, and there are differences in the addition of additives in supercritical multi-fluid and supercritical fluid from quantitative change to qualitative change.
A brief introduction to supercritical extraction equipment
In particular, the new technology of gradual selective extraction, recombinant extraction and distillation extraction of supercritical multi-fluids, including compound traditional Chinese medicine, processing of new preparations of ethnic medicines, deep processing of tobacco, deep processing of tea, marine biological resources, supercritical is a 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 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 uses supercritical water reaction and supercritical carbon dioxide reaction, water and carbon dioxide is no environmental pollution medium, supercritical fluid reaction engineering is suitable for the revitalization of emerging industries in the 21st century green industry application technology, carbon dioxide gas low price, high purity, easy to make , can be recycled in production, effectively reducing costs.
