Supercritical extraction equipment is an efficient chemical separation technology commonly used to extract active ingredients, drugs, spices and chemical products from natural plants. It takes advantage of the characteristics of supercritical fluids to adjust the physical properties of the solvent above the critical point to achieve higher solubility and diffusivity, thereby achieving efficient separation and purification.
In supercritical extraction equipment, the most commonly used supercritical fluid is carbon dioxide (CO2). Carbon dioxide is widely used in the chemical industry because it is low-cost, renewable, non-toxic and easy to operate. By adjusting temperature and pressure, carbon dioxide can be converted between liquid and gaseous states, and has the characteristics of both liquid and gas, making it an ideal supercritical extraction solvent.
In addition, supercritical extraction offers great operational flexibility. The conditions of supercritical extraction can be controlled by adjusting temperature and pressure to adapt to the separation needs of different substances. Compared with other traditional separation methods, the operating conditions of supercritical extraction are more flexible and easier to adjust. This allows supercritical extraction to be used in a variety of application scenarios to meet the needs of different industries.
Supercritical extraction equipment is widely used in pharmaceuticals, food, environment and other fields with its advantages of high efficiency, environmental protection and strong selectivity, providing strong support for the development and innovation of related industries. In the future, with the continuous advancement of science and technology and the improvement of equipment performance, the application prospects of supercritical extraction equipment will be even broader.
