摘　　要：为获取山药片最适干燥层厚度,将山药切片后铺成不同的层数,分别放入烘箱进行干燥试验。再由质量相关指标,即色泽、体积指标、复水率与黏度进行判定,并利用变异数分析山药片干燥层数对干燥速率与质量的影响。试验结果表明,1层与3层生药片干品的质量并无显著差异,其余层的干品无法达到质量外观要求。从干品产量考虑,3层干燥数(1.5 cm厚)为山药片热风干燥的最佳厚度。In order to obtain the optimumdry layer thickness of yams,the yamwas sliced into different layers and put into oven for drying test.The quality-related indicators,namely,color,volume,rehydration rate and viscosity,were used to determine the impact of the dry layer of the yamtablets on the drying rate and quality by using the variation analysis.The results showed that there was no significant difference in the quality between the 1 layer and the 3 layers,and the other layers could not meet the quality requirements.From the perspective of dry product yield,the best thickness for hot air drying was the number of 3 layers(1.5 cmthick).
