采用移动加热板式（Ｍｏｖｉｎｇ ｈｅａｔｉｎｇ－ｐｌａｎｅ ｔｙｐｅ）条件下的颗粒热传递模型推算大型旋转圆盘干燥机的传热系数。在料床完全混合的简化假设下，按物料的干燥特性曲线分段计算圆盘的传热系数及整机总传热系数，其结果与干燥机的实际运行情况基本相符。
The heat transfer coefficient of a large rotating disk dryer is calculated by using the particle heat transfer model under the condition of Moving heating-plane type. Under the simplified assumption that the bed is completely mixed, the heat transfer coefficient of the disc and the total heat transfer coefficient of the disc are calculated according to the drying characteristic curve of the material, and the result basically agrees with the actual operation of the dryer.
