supercritical CO2 fluid extraction
The principle of the supercritical CO2 fluid extraction (SFE) separation process is to use the relationship between the solubility of the supercritical fluid and its density, that is, the effect of pressure and temperature on the solubility of the supercritical fluid.
In the supercritical state, the supercritical fluid is brought into contact with the substance to be separated, so that the components of the polarity, the boiling point, and the molecular weight are selectively extracted in order.
Of course, the extract obtained for each pressure range may not be single, but it is possible to control the conditions to obtain the optimum proportion of the mixed components, and then to reduce the supercritical fluid into a normal gas by means of decompression and temperature rise, and the extracted material is Complete or basic precipitation to achieve the purpose of separation and purification, so the supercritical CO2 fluid extraction process is a combination of extraction and separation processes.
1, supercritical CO2 fluid extraction (SFE) can be extracted near room temperature (35 ~ 40 ° C) and CO2 gas envelope, effectively preventing the oxidation and dissipation of heat sensitive substances. Therefore, the active ingredient of the medicinal plant is maintained in the extract, and the high boiling point, low volatility, and pyrolyzable substance can be extracted at a temperature far below the boiling point thereof;
2. The use of supercritical CO2 fluid extraction (SFE) is the cleanest extraction method. Since the whole process does not use organic solvents, the extract has no residual solvent substances, thus preventing the presence of harmful substances in the extraction process and the environment. The pollution guarantees 100% naturalness;
3. The extraction and separation are combined into one. When the saturated dissolved CO2 fluid enters the separator, the CO2 and the extract rapidly become two phases (gas-liquid separation) and immediately separate due to pressure drop or temperature change. Not only the extraction efficiency is high but also the energy consumption is low, which increases the production efficiency and reduces the cost;
4. CO2 is an inactive gas. It does not react chemically during the extraction process and is a non-combustible gas. It is tasteless, odorless, non-toxic and safe.
5. CO2 gas is cheap, high in purity, easy to prepare, and can be recycled repeatedly in production, thereby effectively reducing costs;
6. Pressure and temperature can be parameters for adjusting the extraction process. By changing the temperature and pressure to achieve the purpose of extraction, the pressure can be fixed by changing the temperature. Otherwise, the temperature is fixed and the extract is reduced by reducing the pressure. Separation, so the process is simple and easy to master, and the extraction speed is fast.
