Product Description: I. Introduction to Supercritical Extraction: Supercritical fluid extraction technology is a novel separation technique in modern chemical engineering. Supercritical CO2 extraction uses CO2 as a solvent, where the fluid density and dielectric constant of CO2 at supercritical state are high, leading to high solubility in substances. This solubility varies sharply with pressure and temperature, offering selectivity for certain substances and easy separation of the solvent and extracted material. Supercritical CO2 extraction is particularly suitable for extracting lipophilic, high-boiling point, and thermosensitive substances, as well as for fine separation of different components, known as supercritical refining. It is used for the extraction and purification of many products, including biological, food, and pharmaceuticals. II. Characteristics of Supercritical CO2 Extraction: 1. Low critical temperature, suitable for the extraction and purification of thermosensitive compounds. 2. Provides an inert environment, preventing oxidation of the product and affecting the active components of the extract. 3. Fast extraction rate, non-toxic, non-flammable, safe to use. 4. No solvent residue, no nitrate and heavy metal ions. III. Supercritical Extraction Experimental Equipment: The equipment mainly consists of an extraction kettle, separator, refining column, CO2 high-pressure pump, auxiliary pump, refrigeration system, CO2 storage tank, heat exchange system, purification system, flowmeter, temperature and pressure control (protection) system. Basic process of the supercritical extraction experimental equipment: 1. CO2 → Extraction kettle → Separator I → Separator II → Recirculation; 2. CO2 → Extraction kettle → Separator I → Separator II → Refining column → Recirculation; 3. CO2 → Extraction kettle → Refining column → Separator I → Separator II → Recirculation; 4. CO2 → Extraction kettle → Separator I → Refining column → Separator II → Recirculation. VI. Combination Forms of Supercritical Extraction Experimental Equipment: 1. Single extraction, one-stage recirculation; single extraction, two-stage recirculation; single extraction, two-stage, one-column recirculation; 2. Double extraction, two-stage recirculation; double extraction, two-stage, one-column recirculation; 3. Quadruple extraction, two-stage recirculation; quadruple extraction, two-stage, one-column recirculation; 4. Note: Special user-defined combination processes are available. VII. Characteristics of Supercritical Extraction Experimental Equipment: 1. Quick opening pressure ring of the extraction kettle, with an imported O-ring, service life of over 4 months. 2. CO2 recirculation use. 3. Design and production according to "GMP" standards. 4. Design and production according to explosion-proof standards. 5. Equipped with a computer data collection and printing system (flow, pressure, temperature). 6. All equipment uses valve stems that have been specially heat treated for durability.
