CO2 Supercritical Extraction System Feature

1. What is supercritical co2?

When the co2 is heated and pressurized to above the critical point, that is, the temperature is higher than 31.19℃ and the pressure is higher than 7.38MPA, at this time CO2 is called supercritical CO2.

2. Is supercritical co2 extraction better than other extraction methods?

Supercritical CO2 has the characteristics of low viscosity, good mass transfer, good expandability, and compressibility. It has a strong ability to dissolve solutes with less polarity without destroying the original properties of the raw materials. CO2 is a natural.so if it escapes into the air during extraction it won't do any harm. It can also be recycled, making this method much more sustainable. Since the solvent isn't toxic, people working with this extraction method don't face any health risks.

In general, supercritical CO2 is a safe, efficient, energy-saving, no residue and pollution-free extraction solvent.

3. What materials can be extracted by supercritical co2 extraction machine？

Supercritical co2 extraction can be used for all water-insoluble substances

Supercritical CO2 Extraction System is well designed for effective oil extraction and easily operation. It is a completely configured system consists of extraction vessels (extractors), separation vessels (separators), Operation front panel, High pressure CO2 Pump, Chilling system, heating system, Pressure regulator valve, Co-solvent pump, CO2 Storage tank, CO2 Recovery pump etc. The users can run the machine to produce essential oils only need to provide with electricity and CO2.
