摘　　要：在玉米花粉的加工过程中 ,为使花粉营养物质能够得到充分利用 ,采用自行研制的可调参数式行星球磨机对玉米花粉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影响关系的数学模型 ,通过优化计算得到玉米花粉超微化破壁的最佳工艺参数为 :公转转速 476r/min ,粉碎时间 1.2h ,球料比 7,花粉含水率小于 5 % ,此时花粉破壁率达 10 0 % ,花粉粒径小于 8μm ,为花粉的实际有效利用奠定了基础。In order to make good use of the maize pollen nourishment material, in the process of the maize pollen, a variable parameter ball mill which was made by ourselves was used to conduct a experiment on superfine grinding maize pollen. An orthogonal experimental design with four factors at two levels was adopted. A mathematical model describing effects of selected parameters on experiment criterion was developed. By means of optimal calculation a set of optimum parameters for the best superfine grinding of maize pollen was achieved with grinding drum rotation speed 476 r/min, grinding time 1.2 h, ratio of ball to maize pollen 7, and moisture content of the maize pollen below 5%. With those parameters, 100% of dilapidated walls for maize pollen were obtained and major diameter of maize pollen was below 8 micrometer, This research result laid a basic foundation for efficient utilization of maize pollen in food and cosmetic industry.
