摘　　要：采用流态化干燥方法对发酵柑橘皮渣的干燥进行实验研究,建立一个小型的流化床干燥试验台,分析了各干燥参数如风温、风速、颗粒粒径、床层高度以及初始含湿率对发酵柑橘皮渣干燥特性的影响。实验表明对于经过预处理的发酵柑橘皮渣介质,采用流态化方式可以获得较好的干燥效果;在各干燥参数中,初始含湿率、风温和粒径对发酵柑橘皮渣干燥特性的影响较为显著。根据实验数据建立了干燥特性回归数学模型,可以为实际生产工艺提供依据。A fluidized drying method was used to research the drying characteristic of zymotic orange peels, and a experimental equipment of fluidized drying bed was built, the influence to the drying characteristic of drying parameters such as air temperature,air velocity, particle diameters, the height of bed layer and the initial moisture content etc, are analyzed. The results indicate that the fluidized drying method is suited to the sample with high moisture content after preprocess, and among the drying parameters, the initial moisture content, air temperature and particle diameter influenced the drying characteristic remarkably. Based on the experiential data, an experiential mathematical model is buildt up, which can provide the direction for real production in the fluidized bed.
