摘　　要：为了优化油菜籽流化床干燥工艺,以热风温度、初始水分和热风风量为主要因素,利用隶属度法将干燥时间、油的酸值、油的过氧化值和发芽率4个指标相结合综合评分,进行响应面优化设计,建立了二次多项式回归模型。结果表明,3个因素对综合分影响大小依次为:热风温度>热风风量>初始水分;油菜籽流化床干燥最优工艺参数为:热风温度为57.93℃,初始水分为22.56%,热风风量为58.66m3/h,此时综合分达最大值0.865。Response surface methodology was adopted to optimize rapeseed fluidized bed drying process. Taking drying time, acid value and peroxide value of rapeseed oil, the germinating capacity of seeds as target parameters, the four factors were scored by using the comprehensive evaluation of the membership--degree method. Hot air temperature, rapeseeds moisture content and volume of hot air were investigated. In addition, the quadratic polynomial regression model was established to optimize the drying techniques. The resuits showed that effects order of three factors on rapeseed fluidized bed drying were as follows： hot air temperature, the volume of hot air, and then rapeseeds moisture content. The optimal parameters of fluid- ized bed drying method for rapeseeds were air temperature of 57.93℃, rapeseed＇s moisture content of 22. 56% and hot air volume of 58.66 m3/h, then the largest comprehensive score of 0. 865 was obtained.
