钢带式果蔬干燥设备温度控制系统设计及优化

摘要

In this article, a temperature control system for a strip-type fruit and vegetable drying equipment is designed.U-sing PID temperature regulator as the core control device, and combined with the temperature regulating valve, the system could control the temperature deviation in the dry compartment within ±3℃, and could provide the control theory and experi-mental data.Therefore, the system could reliably control the temperature so that the actual production drying curve automati-cally fit to the theoretical drying curve of the material.%本设计研发了一种用于钢带式果蔬干燥设备的温度控制系统，该系统采用 PID 温度调节器为核心控制器件，辅以温度调节阀，可使干燥仓内温度偏差控制在±3℃以内，并给出了控制原理及实验数据。该系统控制温度可靠，使生产过程实际干燥曲线自动拟合该物料的理论干燥特性曲线。
