Supercritical Fluid Extraction Plant

Product Details

Supercritical CO2 Fluid Extraction Device:CO2 supercritical extraction is suitable for the extraction and purification of heat-sensitive compounds. Supercritical CO2 extraction is especially suitable for the extraction of fat-soluble, high-boiling point, heat-sensitive substances. It is also suitable for the fine separation of different components, that is, supercritical distillation. Supercritical extraction can provide an inert environment to avoid product oxidation, does not affect the active ingredients of the extract, has fast extraction speed, is non-toxic, non-flammable, safe to use, does not pollute the environment, and has no solvent residue.Features: 1. Supercritical extraction can be performed near room temperature (35-40°C) and under a CO2 gas envelope, effectively preventing the oxidation and escape of heat-sensitive substances. Therefore, the active ingredients of medicinal plants are maintained in the extract, and substances with high boiling points, low volatility, and easy pyrolysis can be extracted at temperatures far below their boiling points; 2. The use of supercritical extraction is a clean extraction method. Since the whole process does not use organic solvents, there is no residual solvent substance in the extract, thus preventing the presence of harmful substances to the human body and pollution to the environment during the extraction process; 3. Extraction and separation are combined into one. When the saturated dissolved CO2 fluid enters the separator, due to the drop in pressure or the change in temperature, the CO2 and the extract quickly become two phases (gas-liquid separation) and are immediately separated. Not only is the extraction efficiency high, but it also consumes less energy, which improves production efficiency and reduces costs; 4. CO2 is an inactive gas. No chemical reaction occurs during the extraction process, and it is a non-flammable gas. It is tasteless, odorless, non-toxic and safe; 5. CO2 gas is cheap, has high purity, is easy to prepare, and can be recycled repeatedly in production, thus effectively reducing costs; 6. Pressure and temperature can both become parameters for regulating the extraction process. The purpose of extraction is achieved by changing the temperature and pressure. Substances can also be separated by fixing the pressure and changing the temperature; conversely, by fixing the temperature, the extract can be extracted by lowering the pressure. separation, so the process is simple and easy to master, and the extraction speed is fast. Applications: The characteristics of supercritical CO2 extraction determine that its application range is very broad. For example, in the pharmaceutical industry, it can be used for the extraction of active ingredients of herbal medicine, the refining of heat-sensitive biological drugs, and the separation of lipid mixtures; in the food industry, the extraction of hops, the extraction of pigments, etc.; in the spice industry, natural and refining of synthetic fragrances; separation of mixtures in the chemical industry, etc. Specific applications can be divided into the following aspects: 1. Extraction of bioactive molecules from medicinal plants, extraction and separation of alkaloids; 2. Lipid lipids from different microorganisms, or used for lipid lipid recovery, or to remove lipid lipids from glycosides and proteins; 3. Extract anti-cancer substances from a variety of plants, especially paclitaxel from the bark, branches and leaves of yew trees to prevent and treat cancer; 4. Vitamins, mainly the extraction of vitamin E; 5. Purify various active substances to remove unnecessary molecules or "drugs" to obtain purified products;   6. Processing of various natural antibacterial or antioxidant extracts, such as basil, basil, thyme, garlic, onion, chamomile, paprika, licorice and fennel seeds, etc.
