Tea from the top of the hopper into the machine, the vibration of the vibrator device, selected material along the channel decline, accelerated down into sorting indoor observation area, and through the sensor and the background plate. In the light of the role, according to the intensity and color of light changes, the system generates an output signal to drive the electromagnetic valve blowing waste cavity blowing to the hopper of the tea color, and good tea continue to fall into the hopper finished cavity, so as to achieve the purpose of the election. The tea color sorter manufacturers work is different from the material and material of the rice grains color selection, because the tea powder so fragile and the characteristics of tea color sorter color channel can only choose the waterfall channel, the purpose is to protect the destruction of the tea color selection process. Tea color sorter is selected photoelectric sensor /CCD lens were selected on the material in tea leaves using color color. Because the tea drying is very easy to break, so as to ensure the quality of the tea material under the premise of improving the color selection accuracy of the selection of tea color selection machine selection of multi-layer mechanical structure.
