Characteristics and Development of Supercritical Extraction Equipment!
The traditional natural product separation method has low purity, complex and cumbersome process, and the extraction rate is not satisfactory. In the specific operation process such as: pressing and heating in the refining process; Processes such as water vapor distillation and solvent extraction often cause certain heat-sensitive or chemically unstable components of natural products to be destroyed during processing, thereby changing the unique flavor and nutrition of natural foods. Moreover, the contamination of solvent residues in the processing process is also inevitable, and supercritical extraction equipment can make up for the defects of traditional processes because of the following characteristics.
Supercritical extraction equipment is highly efficient and the process is easy to adjust. Supercritical fluids have both gas and liquid characteristics, so supercritical fluids have both liquid dissolution ability and good gas flow and transfer performance. And around the critical point, small changes in pressure and temperature have the potential to significantly alter the solubility of the fluid and control the separation process.
Extraction and separation in one. The whole process does not have the phase change process of materials, there is no need to recover solvents, it is easy to operate, not only the extraction efficiency is high, but also the energy consumption is small. The extraction process is usually carried out at low temperatures. It can effectively prevent the oxidation and escape of heat-sensitive components, especially suitable for the separation and extraction of heat-sensitive, easily oxidized and decomposed components such as food aroma components, physiological activities and enzyme proteins.
After more than 20 years of efforts, China's supercritical extraction equipment and technology research and application has made remarkable achievements, especially in the extraction of active active ingredients of biological resources. The characteristics of supercritical extraction equipment determine its wide range of applications. For example, in the pharmaceutical industry, it can be used for the extraction of effective ingredients of herbal medicines, the refining of heat-sensitive biological products, and the separation of lipid mixtures; In the food industry, the extraction of hops, the extraction of pigments, etc.; In the fragrance industry, the refining of natural and synthetic fragrances; separation of mixtures in the chemical industry, etc.
