Abstract: 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.
