奶粉干燥过程控制系统的研究

Research of the control system about the procedure in drying of milk powder

以喷雾干燥塔作为系统的控制对象 ,选用排风温度为控制量 ,以控制喷料量为控制手段 ,从硬件和软件两方面阐述了系统的设计思想和实施过程。系统采用单片机技术 ,实现了多路温度的检测、控制、超温报警。

In this paper,the spraying and drying tower was used as the system control plant,and the temperature of air discharge was used as the control volume.It was the control method by controlling the volume of spraying milk.The design and implementation of the system were given a minute description of hardware and software.Using the single-chip microcomputer,this system fulfils the purposes of multichannel temperature measuring,controlling,overheat alarming,displaying and printing.$$$$
