摘　　要：通过切片厚度、载样量、室内外湿度差的单因素实验,探讨了苹果的脱水效率,并以苹果的脱水速率为指标,利用三因素三水平的响应面分析法优化了苹果太阳能脱水工艺,并建立了回归模型。结果表明,切片厚度、载样量、室内外湿度差对脱水速率均有极显著的影响。切片厚度0·5cm、载样量10kg、室内外湿度差15%时,脱水速率为0·0165%·min-1。The dehydrating characteristics of apple during drying process were studied by the single factor experiments including section thickness,sample load and difference of indoor and outdoor humidity. The drying technology conditions were optimized by response surface analysis at three factors and three levels when guided by integrated indicator of dehydration rate,and the corresponding regression model was established. The results showed that section thickness,sample load and difference of indoor and outdoor humidity had significant influences on the dehydration rate. When drying processing conditions of apple were as follows：section thickness was 0.5cm,sample load was 10kg,and the difference of indoor and outdoor humidity was 15%,the dehydration rate was 0.0165%·min^-1.
