摘要
应用最优化技术进行气流干燥过程分析与干燥器优化设计。提出能耗最低的空气预热温度、入口气速、固气负荷比等最优操作条件．以干燥器直径、高度、预热温度、气体速度及气固比５个因素、５个水平的正交实验，进行计算机模拟，实现了干燥器尺寸设计与操作条件的同时优化，并得到各因素对干燥过程能耗、热效率、物料处理量与终湿含量等技术经济目标的显著性影响顺序．
he optimization analysis and design of pneumatic dryers by optimization technique were described in this paper. The optimum operation conditions with minimum energy consumption were presented for the extant pneumatic drying system. The simultaneous optimization of equipment size and operation parameters were achieved through computer simulation by the orthogonal experiment method of multi-elements and multi-levels. The significant effect sequence of various factors on the object of energy consumption, thermal efficiency, handling capacity of wet material and final moisture content of products was obtained also.
