枸杞烘干窑温湿度控制系统的设计——基于PPC系统

Design of the Temperature and Humidity Control System in the Medlar Drying Kiln——Based on PPC System

枸杞烘干装置温湿度控制系统会影响枸杞烘干工艺的实施和烘干装置的热效率。为此,依据枸杞烘干中温湿度的控制策略,设计出基于PPC系统的枸杞烘干窑温湿度控制系统,编制了控制软件。运行结果表明,该控制系统合理可行。

The temperature and humidity control system of medlar drying kiln can affect the implement of drying technique and thermal efficiency.The temperature and humidity control system based on PPC is designed in the paper according to the control strategy of the temperature and humidity in the process of drying.The control software is also programmed in the paper.Application proves that the control system runs reasonably.
