Supercritical CO2 Extractor
Supercritical CO2 Extractor
Supercritical CO2 extraction technology is a highly efficient and environmentally friendly separation and extraction technology that is widely used in the fields of food, pharmaceuticals and chemicals. The technology utilizes the physical properties of carbon dioxide at a certain temperature and pressure, making it both gas and liquid, thus realizing the efficient extraction of target substances. Supercritical CO2 extraction technology has many advantages, such as not adding organic solvents, no pollution to the extract, and can be extracted at close to room temperature (35 ~ 40 ℃) and CO2 gas shroud, effectively preventing the oxidation and escape of heat-sensitive substances.

What is Supercritical CO2 Extractor
Supercritical CO2 Extractor is a device that utilizes supercritical carbon dioxide (SCCO2) as a solvent for substance extraction. Supercritical carbon dioxide means that under specific temperature and pressure, carbon dioxide is in a special fluid state, characterized by low surface tension, low viscosity and high diffusivity.
The technology works by pressurizing and heating the carbon dioxide to a supercritical state, which is then used to dissolve the target compound. By adjusting the temperature and pressure in the extractor, it is possible to control which compounds are dissolved and extracted. Supercritical carbon dioxide extractors are widely used in the extraction process of essential oils, caffeine and other components of plants, and are favored for their unique dissolution performance and environmentally friendly characteristics.

Use of CO2 as the preferred solvent is because of its ability to create a quality, clean and pure oil that is safe for consumption with limited post processing. The use of other toxic solvents may require additional hours to remove the trapped solvents in the oil after extraction.
The extraction is based on diffusion, a process where fluid CO2 is required to diffuse into the matrix to dissolve the extracted material and in turn cause a flow out of the matrix into the solvent. The extracted material is dissolved and released much faster in supercritical fluids than it does in liquids. Supercritical fluids have negligible viscosities and minimal surface tension compared to that exhibited in liquids.
Therefore, the use of superficial fluid ensures the extraction occurs much faster. Use of the supercritical CO2 solvent is suitable to use in the regular separation systems that separate individual constituents during the extraction process for its tenability, efficiency, and affordability. Also, the use of CO2 supercritical fluid does not only separate constituent components, but it also prolongs its shelf life.
