为了防止茶叶在理条过程中出现色泽变黄、变暗或产生焦味的现象,需要有效地控制理条过程中的温度,提高茶叶的加工质量。将模糊算法与理条过程的温度控制结合,运用Matlab对设计进行仿真及进行理条实验,表明主副加热部件模糊温度控制精度高,超调量小,碎茶率为6%(传统方式碎茶率为11.8%,单一加热部件模糊控制碎茶率为8.3%),理条温度为90℃,评审分数为932.5分,优于传统理条方式与单一加热部件模糊控制理条方式,该研究为提高茶叶理条质量提供了参考。
In order to prevent the color yellow, darker or burnt phenomenon generated in the tea carding, it is needed for effective control of the temperature during the tea carding, to improve the processing quality of tea. The combination of fuzzy algorithm and temperature control of the carding process, the Matlab was aplied in design and simulate, the carding experiment. Results showed that fuzzy temperature control on the main and auxiliary heating component with high precision, and small overshoot, the broken rate of tea is 6% (the traditional way of broken rate is 11.8%, fuzzy temperature control on single heating element broken rate of tea was 8.3%), temperature of 90℃, score is 932.5 points, is better than the traditional control method and the single heating parts, this study provides the reference for improving tea carding quality.
