[Study on the dynamic model of supercritical fluid extraction of effective ingredients from natural plant].
In order to obtain the theoretical mass transfer model in the process of extracting effective ingredients from natural plant by Supercritical Fluid, the mass transfer mechanism was analyzed and the analytical solution of the dynamic model of Supercritical Fluid Extraction was deduced through rational simplifying the differential mass balance equations. The complete extraction time, extraction yield as a function of time and the influence of the diameter of solid material on the extraction yield were calculated by the model and the results of computation fit well with the experimental data of literature. This model can be used to analyze, predict, design and optimize the process of extracting effective ingredients from natural plant by Supercritical Fluid.
