摘要:

分析了影响充气包装气体充填量的因素，对于特定批量产品进行充气包装时，提出了PID控制充填量的方法，给出了PID控制模型和实现方法。杭椒和切片莲藕臭氧充气包装试验表明，利用PID控制气体充填量，可以提高充填精确度，延长货架寿命期。

Abstract:

The influencing factors of gas filling quantity were analyzed. The method of filling quantity PID control was put out for gas packaging of particular batch products. The controlling model and realization method by PID were given. Hangzhou pepper and sliced lotus root ozone gas packaging were tested with the method. The results showed that the accuracy of filling quantity is improved and shelf life is extended.

Key words: gas packaging filling quantity PID control
