摘要
利用自行设计的谷物干燥综合模拟程序模拟分析了预热温度、谷床厚度和换流器位置对横流式谷物干燥机性能的影响。结果表明,预热可降低能耗,提高干燥速率;借助于数学模拟可确定干燥机的最佳结构尺寸参数。首次应用数学模拟方法对干燥机的单位热耗、生产率折算问题进行了研究。利用本文提供的折算方法可解决不同干燥机之间的性能比较和生产作业中的生产率折算问题。
The effect of preheating temperature,grain bed depth and loca- tion of grain inverter on the performance of erossflow grain dryer are simulated and analyzed using Comprehensive Grain Drying Simulation Program (CGDSP) developed ourselves.Simulation results show that preheating may reduce energy consumption and increase drying rate and optimum constructional parameters of grain dryers may be determined by means of mathematical simulation.Conversion coefficients of specific heat consumption and capacity of crossflow grain dryer are studied with simulation technique.By using the conversion method given in this paper, the existing problems in performance comparison among different dryers and capacity conversion during drying production are solved.
