摘要: 为探讨热风干燥山药片最适干燥层数,并为山药的合理加工和开发提供相关依据。试验将山药切成0.5 cm 厚,铺成不同的层数放入烘箱进行干燥试验,再由色泽、体积复水率、重量复水率与黏度4项质量指标进行评定。结果表明:1层与3层干品的质量并无显著差异,其余层数的干品则在外观上已无法达到质量指标要求。结论为从干燥作业的效率考虑,3层即厚度 1.5 cm,可以提高效率,节约能源。

Abstract: In order to explore the optimum number of drying layers for hot air drying and to provide the relevant basis for the rational processing and development of Chinese yam.The yam was cut into 0.5 cm thick,laid into different layers and put into the oven for the drying test,and then evaluated by color,volume rehydration rate,weight rehydration rate and viscosity.The results showed that there was no significant difference between the quality of the first layer and the third layer,while the appearance of the other layers could not meet the quality requirements.The conclusion is that considering the efficiency of drying operation,the optimum drying thickness is 1.5 cm with three yam slices,which can save energy and obtain greater economic benefits.

Key words: Chinese yam, Layer thickness, Hot air drying, Quality
