Study on the extraction of curcuma longa oils with supercritical carbon dioxde and its mathematic model

Xiaojun Hu

Abstract

The extraction of process of curcuma longa oils with supercritical dioxide CO_2wasstudied by using homogeneous experiment.The experiment results showed that the better plan of extracting curcuma longa oils was extracion press 36Mpa, extraction temperature50℃,flux of CO_215kg/h,extaction time 3hours respectively.A mathematic model of extracting curcumalonga oil was esablished.
