摘　　要：采用二次正交旋转组合设计法,对丸粒化玉米种子进行了3因素5水平的干燥试验。通过对试验结果的分析,分别建立了在干燥过程中总能耗和干燥所需时间与风温、风速、介质加热时间之间的回归方程。通过对2个指标回归系数的检验,确定了影响干燥过程总耗能和干燥所需时间的因素主次顺序。通过优化计算,得到单指标和综合指标的最佳参数组合。运用评价函数法得到的最佳参数组合是热风风温38℃,风速5.4m/s及介质加热时间40min。Drying experiment of pelleted corn seed was conducted through three-factor and five-level quadratic orthogonal rotary experimental design. One regression model about the energy consumption ,drying time and three factors of the temperature of the drying medium, air velocity, heating time was obtained. By the examination about the coefficient of two indexes, the sequence factor order of total energy consumption of dry process and required time of drying were determined. By optimization, the best parameter combination about the single index and synthesize index was gotten. Using assessment function method ,the best parameter combination is the drying air temperature 38℃, air velocity 5.4 m/s and heating time 40 min.
