【摘要】 利用热风干燥试验台对熟化甘薯的热风干燥特性进行研究,探讨不同干燥温度、热风风速、铺料密度对干燥速率的影响,其影响因素大小依序为:干燥温度>干燥风速>铺料密度。利用3种不同干燥速率模型对实验数据进行拟合,发现甘薯热风干燥符合Page方程,即,模型拟合F值为1102.35,呈极显著。更多还原

【Abstract】 Researches on the air-drying characteristics of cooked sweet potatoes were conducted on the air-drying test machine. The effects of air temperature as well as velocity and material density on the drying rate were also investigated, and the order from high to low was air temperature >velocity > material density. The experimental data was processed base on three different mathematical models, and the result showed that the drying performance of cooked sweet potatoes agreed with Page equation (viz.), the F value of model fitting was 1 102.35, showed great significance.更多还原
