Brief introduction

Supercritical extraction technology uses the unique properties of carbon dioxide in the supercritical state to realize the extraction and carrying of the effective components of the material, and changes its solubility by changing the pressure and temperature environment of carbon dioxide, because the solubility of carbon dioxide has a hundred-fold difference between the supercritical state and the non-supercritical state, the instantaneous separation of the extract and the dioxide, the carbon dioxide can be recycled, avoid waste, and the collected material is not polluted by any harmful components, which is green and environmentally friendly.
