Supercritical co2 extraction machine/essential oil supercritical fluid extraction

The technology of Supercritical Fluid Extraction is a new subject from Modern Chemicals Industries, which is one of the advanced Separation Technology. As for SCF(Supercritical Fluid), it is was that fluid on Critical Point(Pc, Tc) under Thermodynamic State,  the Critical Point is the state point when interface of Gas and Liquid disappear, which process very novel physical& chemical characters. It density degree close to liquid, viscosity degree close to gas, but bigger diffusion coefficient &dielectric constant, smaller viscosity etc. these characters have contributed to good separation effects. So the SFE is mainly about Separation,  the solution will touch with extracted materials under High Pressure& Suitable Temperature, the Solutes would be diffused into the solution, then change the operation Conditions, to make the Solutes separate out.

Supercritical CO2 Extraction Machine Features

1.Easy to operate and adjust;

2.Well selectivity. Can extract out requested component according to control pressure and temperature.

3.Low operating temperature. Operation often happen under room temperature, which is much better for Heat-sensitive Materials. Because during extraction process, it has avoid “when oxygen oxygenation” and “when light reaction”, product can keep its natural tastes. 

4.Finish within one step, CO2 won’t be left on the products. 

5.CO2 is one kind gas of non-poisonous, tasteless, inflammable, cheap and can be cycle use. 

6.Quick extraction speed.
