CO2 Supercritical Extraction Machine

The CO2 Supercritical Extraction Machine optimizes the extraction efficiency of specific compounds by precisely controlling key parameters, including temperature, pressure, flow rate, time, and sample size. Typically, increasing the pressure to approximately 30-50 MPa enhances the extraction efficiency, while increasing the temperature above 50°C may reduce the extraction of oils from certain green algae. Furthermore, the physicochemical properties of supercritical fluids can be altered by the addition of modifiers (e.g., co-solvents) to improve extraction efficiency.

The typical CO2 supercritical extraction machine apparatus comprises a CO2 source, pressurization apparatus (e.g., pumps), an extraction vessel situated within an oven, an extraction line limiter to maintain the high pressure, and an analyte collection device. The apparatus is typically constructed from stainless steel due to its chemical inertness and ability to withstand high pressures.

The specifications of CO2 supercritical extraction machine vary depending on the manufacturer, with different sizes available. These include laboratory-scale models, which typically range from 50ml to 500ml, and industrial-scale models, which are capable of processing up to 200 litres per extraction vessel. These devices offer precise control of process parameters, are suitable for analytical purposes, and can be customized as needed.

The capital costs of CO2 supercritical extraction machine are higher than those of commercial equipment used for typical extraction processes. However, the benefits of CO2 supercritical extraction machine outweigh the initial costs. They provide a safer and more efficient extraction process than traditional solvent extraction methods and can reduce energy consumption and operating costs.
