【摘要】 以提高蔬菜干制品质为目的,采用自制的微波干燥试验装置,研究了不同干燥功率、物料铺放厚度及排湿风速对干制胡萝卜丝品质和能耗的影响。采用正交试验的极差和方差分析方法,进行了参数综合优化。结果表明:不同微波干燥参数对干制胡萝卜丝品质有显著的影响,物料脱水过程主要处于恒速阶段,微波干燥功率为1.125W/g,铺放厚度为1.5cm,风速为75m/min时,可确保胡萝卜丝干燥后的食用价值且便于储存,而且能耗较低。更多还原

【Abstract】 Experiment was done to study the influence of microwave drying parameters on the quality of dried sliced carrot and energy consumption with home-made microwave drying and testing device by different heating power,thickness of materials and airflow rate.Optimum process has been presented and the process parameters of microwave drying of sliced carrot established by analysis of range and variance of orthogonal experiment.The experimental results showed that the constant speed drying was the main stage of microwave drying of sliced carrot,and the edible quality was maintained after drying process.更多还原
