Supercritical CO2 Extraction technology:
Supercritical CO2 Extraction technology is a new type of extraction technology that uses CO2 in a supercritical state as an extractant. In the supercritical state, CO2 fluid has the dual characteristics of gas-liquid two-phase. It not only has high diffusion coefficient and low viscosity equivalent to gas, but also has similar density to liquid and good dissolving ability for substances. Therefore, in supercritical In the critical state, the supercritical carbon dioxide is contacted with the substance to be separated to selectively extract the components with different polarity, boiling point, and molecular weight in sequence.
Advantages of Supercritical CO2 Extraction technology:
1) The effective ingredients can be preserved in good condition without being destroyed, especially suitable for the extraction of those ingredients that are sensitive to heat and easy to be oxidized and decomposed;
2) No solvent residue, non-toxic and harmless to human body;
3) High extraction efficiency and stable product quality;
4) Environmental protection, no pollution from three wastes, etc.
The composition of the Supercritical CO2 Extraction:
The supercritical extraction device can be roughly divided into eight parts in terms of function: extractant supply system, low temperature system, high pressure system, extraction system, separation system, modifier supply system, circulation system and computer control system. Specifically, it includes equipment such as carbon dioxide injection pumps, extractors, separators, compressors, carbon dioxide storage tanks, and chillers. Since the extraction process is carried out under high pressure, the pressure resistance performance of the equipment and the entire pipeline system is relatively high. The automatic monitoring of the production process by a microcomputer can greatly improve the safety and reliability of the system and reduce operating costs.
Application of Supercritical CO2 Extraction:
Widely used in the agricultural food industry (food additives such as ginger, large leaf cinnamon and other natural products extraction, pesticides and soil pollutants extraction); pharmaceutical industry (manufacturing of natural products such as magnolia, angelica); cosmetics industry (scents, oils, etc.) Extraction) and so on.
