The Science Behind

CO2 Supercritical Fluid Extraction

SUPERCRITICAL CO2

Delivers the Highest

Purity and Consistency
of extracted oils

SUPERCRITICAL CO2

Has the Highest Efficiency

in extraction of natural

essential oils available

Advanced Manufacturing - the CO2 Supercritical Fluid Extraction bio-technology platform is  advanced manufacturing. CO2 Supercritical Fluid Extraction process has emerged as the alternative to the traditional solvent extraction process. It is a separation technique, which is developed by use of the fluid that has the ability of dissolution at supercritical pressure and supercritical temperature.

The Benefits of CO2 Supercritical Extraction

CPF Green Solutions Pty Ltd has chosen CO2 Supercritical Fluid Extraction as our extraction method of choice compared to Ethanol, Butane (BHO), Propane (PHO) and Steam. Each has its own benefits and negatives.

  • CO2 Extraction METHOD: is Clean, Efficient, Safe, and Versatile.

  • CO2 is CLEAN:- and has been used in many established industries for decades. 

  • CO2 is EFFICIENT:- with high pressure like 5000+/Psi, gives operation a greater tunability and faster extraction times. 

  • CO2 is SAFE:- non-toxic, odourless, non-flammable, low-cost and recyclable. 

  • CO2 is VERSATILE:- meaning the extraction equipment can be tune to utilise the flexible nature of food grade CO2 to target different specific botanical materials, leveraging the versatility of CO2 in an effort to pull all of the valuable goodness out the botanical material being processed.

CO2 Supercritical Fluid Extraction is a new separation bio-technology in modern chemical separation and the superior method for botanical fluid extraction.

Supercritical Fluid refers to fluid in the thermodynamic state which is above the Critical Point. The Critical Point is the state where distinct gas and liquid phases do not exist. Supercritical Fluid has its unique physical and chemical properties, it is almost as dense as liquid and as viscosity as gas, it can effuse through solid botanical material like a gas, and dissolve materials like a liquid. Many characteristics, like high diffusion coefficient, low viscosity, and large dissolvability, etc prompt goods separation effect. 

CO2 Supercritical Fluid Extraction means that the solvent and extracted substances in the extraction kettles, under high pressure and appropriate temperature, the  solvent diffuses into the kettle, and changers the operating conditions to separate the dissolved substance.

CO2 Supercritical Fluid Extraction device takes food grade CO2 Gas as the solvent, which has many characteristics:

  1. Wide operating range and easy to adjust.

  2. By controlling pressure and temperature, extract the required ingredients.

  3. Low operating temperature, closed to room temperature, which is especially suitable for heat sensitive components. In the extraction process, the possibility of oxygenation and light reaction is excluded, and can maintain its natural flavour.

  4. Can finish extraction to separation in one step, and there will no residual components in the extracted material.

  5. CO2 is non-toxic, odourless and non-flammable.

  6. Fast extraction speed.

With the rapid development in recent years, CO2 Supercritical Fluid Extraction has successively realized industrialization in the fields of hops, spices, herbs, food health care and untainted food waste.
