| 摘 要： | 热风干燥是红枣干燥加工中应用最为广泛的干燥技术之一。在红枣热风干燥技术的研究方面,干燥设备的工艺优化、干燥室温、湿度等参数的稳定控制等方面仍有待优化与提升。为此,针对目前主要的热风干燥设备的特点,综合南疆红枣的加工特点,利用PLC控制技术与HMI在线控制技术,设计了一种调质红枣干燥机,对干燥机温度进行了多段控制,优化了温度控制系统。通过实验样机进行了干燥加热试验,测试了样机的各项性能指标。结果表明:调质干燥机预热阶段试性能良好,在目标温度为60℃时,预热时间为20min,预热效果良好;干燥机出口风温与干燥室内风温温差约为10℃,热风通道中的传热性能良好;风机电流输出稳定,调速性能良好。调质红枣干燥机进行300min加热试验表明:多段控制方式下,电加热器进行分段加热控制,使干燥室温度稳定在目标温度,获得了较优的控制效果。此研究可为南疆中小型红枣干果加工厂干燥设备的设计提供参考。

| Abstract: | the hot air drying is red jujube dry processing one of the most widely used drying technology .In the study of red hot air drying technology , drying equipment in the process of optimization , the parameters such as drying at room temperature , humidity stability control remains to be optimized and ascend .In this paper , aiming at the main characteris-tics of hot air drying equipment , integrated processing characteristics of southern Xinjiang red jujube , using PLC control technology and HMI online control technology , we design a conditioning red jujube dryer , has carried on the multistage to dryer temperature control , temperature control system was optimized .Dry heating test ,tested by experimental prototype of the technical specifications of the prototype ,the results show that tempering drying machine preheating stage performance is good, the target temperature of 60℃, preheating time for 20 min, preheating effect is good.Dryer export wind temperature and wind in drying chamber sent about 10℃, the heat transfer performance is good in hot air channel;Stable output current , fan speed control performance is good . Conditioning heating test showed that red jujube dryer for 300 minutes more control mode , the electric heater of segmented heating control with the drying chamber temperature sta-bility in the target temperature , the optimal control effect were obtained .Research for the southern Xinjiang small and medium-sized red jujube fruit processing plants provide drying equipment design reference . |
