Small scale supercritical co2 extraction machine
Why use a supercritical CO2 extraction machine?
When carbon dioxide is pressurized to about 7MPA at room temperature, it will become a gaseous liquid and ambiguous state, which we call supercritical fluid. However, the previous extraction uses organic solvents as solvents, which will cause problems such as residues. After using supercritical fluid carbon dioxide as a solvent to extract the effective ingredients, the pressure will vaporize, so there will be no residues, only extraction. Object. The extraction speed of Small scale supercritical co2 extraction is fast, non-toxic, non-flammable, safe to use, and does not pollute the environment.
What are the advantages of supercritical CO2 extraction machine?
1.The production process is green and environmentally friendly: the extraction medium CO2 used is non-toxic, harmless, has good chemical resistance, and does not produce any harmful and toxic substances during the production process;
2.Due to the characteristics of CO2, no organic solvent is used in the production process, and there is no solvent residue.
3.Supercritical CO2 has strong permeability and solubility, fast extraction speed and high extraction degree.
4.The extraction and separation temperature is low, generally at 30-50°C, which will not change the characteristics of the raw materials;
5.It can provide an inert environment to avoid product oxidation and does not affect the effective components of the extract.
6.Integration of extraction, separation and purification.
Application range of supercritical CO2 extraction machine:
1.Extract biologically active molecules from medicinal plants, extract and separate alkaloids;
2.Lipids from different microorganisms, or used for the recovery of lipids, or to remove lipids from glycosides and proteins;
3.Vitamins, mainly the extraction of vitamin E;
4.Purify various active substances (natural or synthetic) to remove unnecessary molecules (such as removing pesticides from vegetable extracts) or "dregs" to obtain purified products;
5.Processing of various natural antibacterial or antioxidant extracts, such as basil, string red, thyme, garlic, onion, chamomile, chili powder, licorice and fennel seeds, etc.
