摘要
采用基于传热传质分析的偏微分干燥模型作为优化计算的基本模型,给出了模型的目标函数、约束条件和求解方法,编制了优化程序,并对5HT-15型谷物干燥机进行了结构参数和操作工艺参数的优化计算。这种优化模型计算精度高,适用范围广,改变少数语句即可进行不同型式干燥机的优化计算。该方法可用于指导生产实际。
Partial differential equation model is used as the basic model for opti- mization of grain dryers.The objective function,constraint condition and solve method of the model are given and an optimization computer program is developed. This model has high accuracy and wide range of applicability.By changing a few sentences in the computer program,different types of grain dryer can be optimized. An optimum calculation for cross flow grain dryer 5HT-15 is conducted and the op- timum structure parameters and technological parameters are obtained.This method can be used for optimal design of productive grain dryers.
