Product features
1) supercritical fluid CO2 extraction and chemical extraction
     (1) It can be extracted at near room temperature (35-40 C) and in the presence of CO2, effectively preventing the oxidation and escape of heat-sensitive substances. Therefore, all the components of the medicinal plant are maintained in the extract, and the high boiling point, low volatilization and pyrolytic substance can be extracted at the boiling point temperature.
     (2) the use of SFE is the most clean extraction method, because the whole process does not use organic solvents, so the extract has no residual solvent, and it also prevents the poisoning of the human body and the pollution of the environment. It is a pure natural 100%.
     (3) the combination of extraction and separation is one. When the dissolved substance CO2-SCF flows through the separator, the CO2 and the extract quickly become two phases (gas-liquid separation) due to the pressure drop, and the extraction efficiency is high and the energy consumption is less, and the cost is saved.
     (4) CO2 is a kind of inert gas, the extraction process does not occur chemical reactions, and is a non-flammable gas, odorless, non- toxic, so the safety is good;
     (5) CO2 is cheap, high purity, easy to obtain and circulate in the production process, thereby reducing costs.
     (6) both pressure and temperature can be used as parameters for adjusting the extraction process. The purpose of extraction is achieved by changing the temperature or pressure. When the pressure is fixed, the material can be separated by changing the temperature; conversely, the temperature is fixed and the pressure is reduced to separate the extract, so the process is simple and easy to master, and the extraction speed is fast.
2) characteristics from the nature of supercritical fluid
    (1) high extraction speed and liquid extraction, especially suitable for separation and extraction of solid substances.
    (2) It is suitable for separating heat-sensitive substances from oxidizable substances because its energy consumption is lower than that of ordinary distillation.
    (3) the heat transfer rate is fast and the temperature is easy to control.
    (4) suitable for the separation of volatile substances .
Technical application
The extraction of seabuckthorn oil, the decaffeinin of coffee beans, the removal of nicotine from the tobacco, the extraction of the coffee flavors, the extraction of useful ingredients in the hops, the extraction of high purity oil from the star oil, the extraction of the cholesterol from soybean oil and egg yolk, and the extraction of Allicin.
Technological process
Empty CO2
Cooling water → CO2 →low temperature bath → high pressure pump →preheater →extractor → separator →product.


The technology of SFE(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.


1,Easy to operate and adjust,well selectivity. Can extract out requested component according to control pressure and temperature.

2,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.

3,Finish within one step, CO2 won’t be left on the products,CO2  is one kind gas of non-poisonous, tasteless, inflammable, cheap and can be cycle use.

4,CO2 can be recycled, and be equipped with return circuit which saves gas.Adopt new methods of fluid distribution uniform fluid distribution, which makes CO2 fluid and solute uniform contact to speed up the dissolved, shorten extraction time, increase production

5,Each kettle has function of measuring and controlling temperature system, which can effectively and accuracy control the temperature.

6,The safety valve can protect the safety of the machine and operator, and the pressure safety display to ensure that the machine working in a safe environment

7,High precision pressure valve to ensure the tightness of the machine,make good extract effect.
