摘　　要：为了给红枣热风干燥设备及干燥过程的控制、预测提供理论依据,利用电热鼓风干燥箱进行红枣热风干燥试验,分析其在不同热风温度、初始含水率和装载量条件下的干燥特性并进行感官品质分析。试验表明:红枣的整个干燥过程只有一个降速阶段,干燥初期降速较快,末期降速缓慢;温度对红枣的干燥速率及感官品质影响最大,装载量次之,初始含水率只对干燥速率有影响。For red hot air drying equipment and drying process provide theoretical basis for the control and prediction,Red jujube in electrothermal blowing hot air drying test,to analyze its in different hot blast temperature,initial moisture content and loading capacity under the condition of drying characteristic curve and sensory quality analysis.Experiment showed that the red jujube the whole drying process is only one speed down stage,the early stage of drying speed down rapidly and at the end of slow down slowly.Temperature on the drying rate and sensory quality of jujube,load times.The initial moisture content only have an effect on the drying rate.

关 键 词：红枣 热风干燥 干燥速率 感官品质
