Supercritical fluid co2 extraction machine for essential oil

Supercritical fluid extraction(the SFE) is an application of a strong green separation technology, adopts CO2 as the solvent. Supercritical CO2 fluid under greater density and dielectric constant, the solubility of the material is large, and with the pressure and temperature changes rapidly changing, therefore, not only the solubility of certain substances selective, and easy separation of solvent and extract. Compared with conventional separation methods, has low extraction temperature strong selectivity, high efficiency, low energy consumption, no pollution and other characteristics, especially for fat-soluble, high boiling point, heat sensitive material extraction, but also for different components Fine separation. Widely used in pharmaceutical, food industry, health care products, cosmetics, perfume an other industries.

1) Low critical temperature suitable for extraction and purification of heat sensitive compound.

2) Being capable to provide inert environment to avoid oxidation of products and affection of effective content of extracts.

3) Fast extraction speed, no toxicity, non-flammable, safe application and no pollution upon environment.

4) No residue of solvent, no nitrate and ions of heavy metal.

5) The press ring of the extraction kettle can be opened quickly; O-ring is imported with service period over 4 months.

6) CO2 can be used in circulation.

7) It can be designed and manufactured as per GMP standard.

8) The pressure stabilizing system of the extraction kettle is imported back-pressure valve.

9) It can be controlled with computerized automatic control system (temperature, pressure, flow etc.)

10) All valves of the device are under special heat treatment so they are robust and durable.

 We can design and manufacture combination type of small & pilot device of different extractor according to customers' requirements, design and manufacture 1000L large-scale superciritical CO2 extraction device.
