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。

Abstract：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 mult-i 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 8μm．T his 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 ℃ handled4times 82％ of dilapidated walls．T he method of superfine grinding is super to range of temperature on dilapidated walls of maize pollen．
