为了确定薄层黄花菜的最佳干燥温度,将薄层黄花菜分别在60,70,80,90,100 ℃温度下进行干燥试验.结果表明,热风干燥温度低于80 ℃时,干燥时间长(2～5 h),干制品形态饱满,呈黄色;干燥温度高于90 ℃时,干燥时间短(1.5～2 h),产品呈褐色的油条状,由此确定薄层黄花菜的最佳干燥温度为80～90 ℃.同时建立了薄层黄花菜干燥的数学模型MR=e -rtn(r=e-4.31+0.056T,n=0.522+0.010 07T,T为温度),可较好地描述干燥过程中物料含水率与干燥时间的关系.

In order to establish the optimal temperature for drying thin layer day-lily, t he experiment was carried out in dry hot temperature of 60,70,80,90 and 100 ℃ r espectively.The results show that when the temperature is less than 80 ℃ ,dryin g time is between 2 hours and 5 hours and product is thin and yellow, while, whe n the temperature is more than 90 ℃, drying time is between 1.5 hours and 2 hou rs and product is thick and brown, so the optimal temperature for drying thin la yer day-lily is 80～90 ℃.Meanwhile the mathematical model MR =e~...
