What are the functions of supercritical extraction equipment?

Author:


Supercritical extraction equipment has solvent residue, low extraction rate and other problems, the application of supercritical carbon dioxide fluid extraction technology has dealt with these problems, product purity has greatly improved, carbon dioxide is easy to dissolve, after the extraction is installed by fire, plant factors are eluted by water, carbon dioxide continues to cycle, sometimes activated carbon instead of water to elute plant factors, with the development of technology, the extraction of plant factors process has been greatly improved.

The extractant used in the extraction equipment is a supercritical fluid. A supercritical fluid is a non-gaseous and non-liquid state of matter between gas and liquid, which can only dry up when its temperature and pressure exceed the critical point. Supercritical fluids have a greater density, similar to liquids, and their viscosity is closer to that of gases. Therefore, supercritical fluids are an ideal extractant.

 

The semi-continuous consumption method of General Foods' Sol Norman Katz is characterized by the fact that when feeding and discharging regularly, the material will be convectioned with the solvent in the equipment, so that the concentration of plant factors in the carbon dioxide fluid will be greatly increased, and the extracted non-plant factor components will return to the substance, so the extracted coffee flavor is still authentic.
