Supercritical fluid extraction equipment can be divided into two major categories. One is research and analysis, which is mainly used for the analysis of a small amount of substances or production data. Followed by production-oriented production, mainly used for mass production or mass production.
Supercritical CO2 fluid extraction equipment ( SCFE ) can be roughly divided into eight functional areas:
Including: carbon dioxide injection pumps,extractors,separators,compressors,carbon dioxide tanks,chillers
Because the extraction process is performed under high pressure, the pressure resistance performance of the supercritical fluid extraction equipment and the entire pipeline system is required to be high. The production process is automatically monitored by the computer, and the safety and reliability of the system are greatly improved, and the operating cost is reduced.

Supercritical fluid extraction is the world's most advanced physical extraction technology, known as SFE ( Supercritical fluid extraction ).
At lower temperatures, the gas turns into a liquid as the gas pressure increases. As the pressure increases, the volume of the liquid increases. There is always a critical temperature ( TC ) and critical pressure for a particular substance ( PC ). Above the critical temperature and critical pressure, the material does not become liquid or gas, which is the key point.
In the range above the critical point, the state of matter lies between the gas and the liquid, and the fluid in this range becomes a supercritical fluid SF .
The supercritical fluid has a strong permeability similar to that of a gas and a high density and solubility similar to that of a liquid, has good solvent properties, and can be used as a solvent for extracting and separating monomers.
Supercritical CO2 fluid extraction ( SCFE ) is a high-tech that emerged in modern chemical separation. SCFE combines traditional distillation and organic solvent extraction, and utilizes the excellent solvent power of supercritical CO2 to effectively separate, extract and purify the matrix and extract.
CO2 is a safe, non-toxic and inexpensive liquid. Supercritical CO2 has a similar gas diffusion coefficient, liquid solvency, zero surface tension, can quickly penetrate into solid materials, extract its essence, has high efficiency, is not easy to oxidize, Pure natural, no chemical pollution and other characteristics.
Supercritical fluid extraction separation technology is the use of supercritical fluid the solvency and its density is closely related to change the pressure or temperature so that the density of the supercritical fluid greatly changed. In the supercritical state, the supercritical fluid is brought into contact with the material to be separated, so that it selectively extracts components having different polarity levels, boiling points, and relative molecular masses in order.
Pharmaceutical industry: it can be used for the extraction of active ingredients of Chinese herbal medicines, the purification of thermosensitive biological products, and the separation of lipid mixtures.
Food industry: the extraction of hops, the extraction of pigments, etc. In the perfumery industry, refinement of natural and synthetic fragrances;
Spice industry: refining of natural and synthetic spices;
Chemical industry: Separation of mixtures, etc.
CO2 dioxide can be said to be the most widely used supercritical fluid. This is mainly because it has no toxicity, low critical temperature and low price.
The research areas that have attracted the most attention in recent years are mainly in the extraction of functional ingredients, fiber dyeing technology, cleaning of semiconductors, particle production of special pharmaceutical ingredients, dry cleaning technology, chemical reaction, and supercritical fluid net meter technology.
Comparison of Supercritical CO2 Fluid Extraction ( SCFE ) and Chemical Extraction
(1) The extraction can be carried out at a temperature close to room temperature (35-40°C) and CO2 gas, effectively preventing oxidation and emission of heat-sensitive substances. Therefore, all components of the medicinal plant are maintained in the extract, and the high boiling point, low volatility, and easily pyrolyzable substances can be extracted below the boiling point of the medicinal plant.
(2) The use of SCFE is the cleanest extraction method. Because no organic solvent is used in the whole process, the extract has no residual solvent, and it also prevents the extraction process from harming the human body and the environment. It is 100% pure natural.
(3) Extraction and separation are combined into one. When the CO2-SCF saturated with dissolved substances flows through the separator, the CO2 and the extract rapidly separate into two phases (gas-liquid separation) due to the pressure drop, and they are separated immediately. And less energy consumption, cost savings;
(4) CO2 is an inactive gas. No chemical reaction occurs in the extraction process. It is non-flammable gas, odorless, odorless, and non-toxic, so it has good safety; (5) CO2 is cheap, high in purity, easy to obtain, and recycled in the production process, thereby reducing costs;
(6) The pressure and temperature can be used to adjust the parameters of the extraction process by changing the temperature or pressure to achieve the purpose of extracting the fixed pressure, change the temperature can separate the substance; the other hand, the temperature is fixed, reduce the pressure to extract the extract, so the process is simple and easy to grasp, and Extraction speed.
