本文介绍了一种成功地应用于味精生产工艺的发酵过程微型计算机自动控制软件系统。该系统以TP—86A单板计算机为主控设备,完成对发酵过程主要工艺参数的闭环实时控制和自动监测记录。经生产实践验证,该系统具有操作简便、修改工艺参数灵活、监测显示参数直观调节控制平稳可靠等优点,对于提高味精产量、质量,降低生产成本减轻工人劳动强度等都具有实际意义。 This paper introduces a micro-computer automatic control software system of fermentation process successfully applied to MSG production process. The system uses TP-86A single-board computer as the main control equipment to complete the closed-loop real-time control and automatic monitoring and recording of the main process parameters of the fermentation process. The production practice has proved that the system has the advantages of simple operation, flexible process parameters modification, stable and reliable control of the visual display and monitoring of the parameters and the like, which is of practical significance for improving the production and quality of the MSG, reducing the production cost and reducing the labor intensity of the workers.
