摘　　要：在目前的红枣热风干燥设备应用中,湿度控制得好坏对红枣的品质观感均产生了较大的影响。为此,设计研发了一种红枣干燥机械湿度自动控制系统。系统采用SIEMENS PLC-200软件平台,通过控制加湿装置产生高压水雾对红枣干燥中期进行定时加湿,使红枣干燥过程中保持高温高湿的干燥环境。通过对系统的调试运行测试,检验了该系统稳定性与可靠性。在干燥室温度变化不大的情况下,湿度值稳定在51.6%左右,且能实现干燥过程中的湿度自动调节。In the current application which is hot air drying equipment of red dates, humidity control has great influence on the quality of red dates. Point at the humidity regulation problem of red dates in the drying process, an automatic con- trol system of red dates drying machinery humidity was designed. The system uses soft ware platform of SIEMENS PLC- 200, timing humidify has been make in the drying medium by controlling the humidifying device to produce the high pres- sure water mist for keeping dry environment of high temperature and high humidity in the drying red dates process. By debugging and running the system testing, the stability and reliability of the system were tested. When the drying room temperature changes not so much, humidity value is stable around 51.6% , and it can achieve the automatically regula- tion of humidity in drying process.
