杀菌处理是生产罐头食品的关键环节,目前,这一过程的实现全靠人工操作。为确保罐头质量,减轻工人劳动强度,提高劳动生产率,我们研制了WKG-2型杀菌锅微机控制系统。该系统采用DDC方式,去掉WKG-1控制仪的温度闭环控制过程中间环节,提高了性能价格比。运行以来,控制稳定、精度高,用户反应良好。本系统为一分时控制、实时处理的群控系统,可以控制4台CT7C5卧式杀菌锅,分别按各自的罐头工艺规范杀菌处理,各自独立,互不干扰。本系统对杀菌过程的温度、压力、时间等参量进行自动控制、显示,绘制温度、压力曲线。且具有温度、压力超调声光报警, Sterilization is the key to the production of canned food, at present, the realization of this process depends entirely on manual operation. In order to ensure the quality of cans, reduce labor intensity and increase labor productivity, we have developed the WKG-2 type sterilization pan microcomputer control system. The system uses DDC mode, remove the WKG-1 controller temperature of the closed-loop control of the middle part of the process to improve the cost performance. Since operation, the control is stable, the precision is high, the user responds well. The system is a time-sharing control, real-time processing of the group control system, you can control the four CT7C5 horizontal sterilization pot, respectively, according to their canning sterilization process specifications, their independent, without disturbing each other. The system of sterilization process temperature, pressure, time and other parameters for automatic control, display, draw the temperature and pressure curves. And with temperature, pressure overshoot sound and light alarm,
