摘要
设计了超临界ＣＯ２萃取－精馏系统和超临界ＣＯ２止逆分布器，并在该系统上进行了小麦胚芽油的萃取－精馏试验研究。研究结果表明，超临界ＣＯ２萃取－精馏比单纯的超临界ＣＯ２萃取操作对小麦胚芽油中维生素Ｅ的浓缩、色素及胶质的脱除效果更显著。
A system of supercritical CO 2 extraction distillation and a unit of preventing CO 2 from back flow and distributing CO 2 were designed. Experiment on extraction distillation of wheat germ oil was carried out in this system. The results indicated that effect of supercritical CO 2 extraction distillation on concentration of V E and remove of pigment and gum of wheat germ oil is more obvious than supercritical CO 2 extraction.
