Tea leaves enter the machine from the hopper on the top. Through the vibration of the vibrator device, the selected materials slide down along the channel, accelerate to fall, enter the observation area in the sorting room, and pass between the sensor and the background plate. Under the action of the light source, according to the intensity and color change of the light, the system generates an output signal to drive the solenoid valve to work and blow out the colorful tea leaves into the waste cavity of the receiving hopper, while the good tea leaves continue to fall into the finished product cavity of the receiving hopper, so as to achieve the goal of sorting. The work of the tea color sorter manufacturer is different from the color separation of rice materials and miscellaneous grain materials. Because of the characteristics of fragile and powdery tea, the color separation channel of the tea color sorter can only choose waterfall channel, in order to protect tea from damage in the process of color separation. The tea color sorter uses the photoelectric sensor / CCD lens to screen the different color leaves in tea materials. Because tea leaves are easy to break after drying, in order to improve the precision of color selection on the premise of ensuring the quality of tea materials, the multi-step mechanical structure is selected for the tea color sorter.
