摘　　要：进行了温差法和超微化法进行玉米花粉破壁实验研究,采用多因素分析和二次回归正交旋转试验设计的方法,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:转速176r/min,粉碎时间为1.2h,球料比为7,花粉含水量控制在5%以下。此时花粉颗粒径小于8μm,花粉破壁率达100%;得到利用温差法最佳工艺参数为:温差为254℃,处理次数4次,花粉破壁率为82%以上。且超微化破壁优于温差法破壁。An experimental study on dilapidated walls of maize pollen with superfine grinding and range of temperature technology are carried out using a variable parameter ball mill.Based on multivariable analysis and orthogonal experimental design of regression method,mathematical model describing effects of selected parameters on experiment criterion is developed.By means of optimal calculation a set of optimum parameters for the best superfine grinding of maize pollen is achieved with grinding drum rotation speed 476 r/min,grinding time 1.2 h,weight rate of ball and maize pollen 7,and moisture content of the maize pollen blow 5%.With those parameters,100% of dilapidated walls for maize pollen is obtained and major diameter of maize pollen is below 8 μm.This research result laid a basic foundation for efficient utilization of maize pollen in food and cosmetic industry.By means of range of temperature achived a set of optimum parameters:range of temperature 254 ℃,handled 4 times,82% of dilapidated walls.The method of superfine grinding is super to range of temperature on dilapidated walls of maize pollen.
