Abstract: According to the hand tea frying craftwork of Xinyang Maojian, an intelligent tea frying machine control system was designed by applying the VFD-E inverter with inner PLC. In the tea frying process, the system switched the stir direction at a certain time interval, and acquired the heating temperature real-time of the tea, the temperature was inputted to the inverter analog channels. The inverter outputed corresponding frequency value directly to control the motor speed of the tea frying. The system had achieved the simulation of the hand tea frying craftwork in the whole
