ZZKD is specialized in Lab instrument for extraction,supercritical co2 extraction equipment is our main product. supercritical co2 extraction equipment is also called SFE,Supercritical extraction has high extraction efficiency and no residue.
Supercritical extraction can be carried out at close to room temperature (35-40°C) and under the envelope of CO2 gas, which effectively prevents the oxidation and dispersion of heat-sensitive substances.Therefore, the effective ingredients of medicinal plants are kept in the extract, and the substances with high boiling point, low volatility, and easy pyrolysis can be extracted at a temperature far below their boiling point.
The use of SFE is the cleanest extraction method. Since the whole process does not use organic solvents, there are no residual solvents in the extract, thereby preventing the existence of harmful substances to the human body and pollution to the environment during the extraction process, and ensuring 100% purity Naturalness.
Extraction and separation are combined into one. When the saturated dissolved CO2 fluid enters the separator, the CO2 and the extract quickly become two-phase (gas-liquid separation) due to pressure drop or temperature change and separate immediately.Not only the extraction efficiency is high, but the energy consumption is less, but also the production efficiency is improved, and the cost is also reduced;
CO2 is an inactive gas, no chemical reaction occurs during the extraction process, and it is a non-flammable gas, tasteless, odorless, non-toxic, and very safe;
CO2 gas is cheap, high in purity, easy to prepare, and can be reused in production, thereby effectively reducing costs;
Both pressure and temperature can be used to adjust the parameters of the extraction process. By changing the temperature and pressure to achieve the purpose of extraction, the substances can also be separated by changing the temperature;On the contrary, the temperature is fixed, and the extract is separated by reducing the pressure, so the process is simple and easy to master, and the extraction speed is fast.
The characteristics of supercritical CO2 extraction determine its wide range of applications.For example, in the pharmaceutical industry, it can be used for the extraction of effective ingredients of Chinese herbal medicine, the refining of heat-sensitive biological products and the separation of lipid mixtures;In the food industry, it is used for the extraction of hops, the extraction of pigments, etc.;In the perfume industry, the refining of natural and synthetic perfumes;Separation of mixtures in the chemical industry, etc.Specific applications can be divided into the following aspects:
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. Anti-cancer substances are extracted from various plants, especially paclitaxel is obtained from the bark and branches of Taxus to prevent cancer;
4. Vitamins, mainly the extraction of vitamin E;
5. Purify various active substances (natural or synthetic) to remove unnecessary molecules (such as removing pesticides from vegetable extracts) or residues to obtain purified products;
6. Processing of various natural antibacterial or antioxidant extracts, such as basil, string red, thyme, garlic, onion, chamomile, chili powder, licorice and fennel seeds, etc.
