In this study, a variable parameter planetary ball mill was used for the superfine grinding of Sophora alopecuroides L.in order to achieve the full release of intracellular components.An orthogonal experimental design with four factors at two levels was adopted.A mathematical model describing the effects of selected parameters on the experimental criterion was developed.By optimal calculation, a set of optimum parameters for the best superfine grinding of S.alopecuroides was achieved as follows: grinding drum rotation speed 340 r/min, grinding time 2.44 h, ratio of ball to S.alopecuroides 8, and moisture content of S.alopecuroides 5.16％.The optimized superfine grinding gave a cell wall disruption efficiency as high as 100％.This investigation can provide useful experimental evidences for the efficient utilization of S.alopecuroides in cosmetic industry.%在苦豆子的加工过程中,为使苦豆子的有效成分能够得到充分释放利用,采用可调参数式球磨机对苦豆子进行了超微化破壁试验研究.采用四因素二次回归正交旋转组合试验设计的方法,建立了试验因素与试验指标间关系的数学模型,通过优化计算得到了苦豆子超微化破壁的最佳工艺参数,为:转速340 r/min,粉碎时间2.44 h,球料比8,物料含水率5.16%,此时苦豆子破壁率达100%,为苦豆子的实际有效利用奠定了基础.
