  • Product Introduction

Supercritical carbon dioxide extraction technology is a subject in modern chemical separation, and it is a separation process that has emerged in the world. All supercritical fluids refer to fluids whose human mechanical state is above the critical point (Pc, Tc). The critical point is the state point where the gas-liquid interface has just disappeared. Supercritical fluids have very unique physical and mechanical properties. Its density is close to jade liquid, its viscosity is close to gas, and its diffusion coefficient, viscosity is small, dielectric constant and other characteristics make its separation effect better and it is a good solvent. Supercritical extraction means that under high pressure and under appropriate turbulence, the solvent is contacted with the extract in the extraction cylinder, the solute is diffused into the solvent, and then the operating conditions are changed in the separator to separate the dissolved substances. The equipment is widely used in biological, pharmaceutical, food and other fields.
