Design of fluidized bed drying control system based on Kingview

Abstract:Drying technology is an important part of the production process, affecting the quality of the product.Improving the design of the drying technology and the correct operation of drying process is the responsibility of each producers, researchers, which also can make the products to ensure quality and safety, and in the process of industrial application, convection drying method is the most extensive in the application of dry solid. This topic is based on Kingview for the design of fluidized bed drying control system. This paper mainly introduces the working principle and process of fluidized bed drying as well as part of the Kingview software and method of use. Designed fluidized bed as controlled object, the temperature of the fluidized bed temperature as controlled variable control system, and made on kingview software monitoring interface of the control system of fluidized bed, together with PID control algorithm, the learning to realize the automatic control of the fluidized bed drying system.

Keywords： Fluidized bed;Kingview;PID
