Explanation of the components and working principle of the tea color selector
Photoelectric system: the photoelectric system is the core part of the color selector, mainly consists of light source, background plate, digital camera and related auxiliary device. The light source provides a stable uniform illumination for the material being tested and the background plate. The photoelectric detector transforms the reflected light of the measured material into electrical signals in the detection area. Tea color sorter IPC new generation digital signal processor to replace the traditional, and the use of fuzzy logic algorithm and support vector machine algorithm, the background plate angle and feed speed automatically adjust, realize the automatic control of the color sorter, and make the performance of the machine automatically reach the optimal state at work. At present, a Thai Ming Photoelectric Technology Co. Ltd. color sorter equipment color sorting machine, industrial color selector, grain color sorter, used in many industries of the color selection requirements.
Tea color sorter mainly comprises: a feed hopper, vibrating feeder, chute, light source, background plate, photoelectric detector, digital camera, one slot, slot jet, genuine valve, air compressor, air purifier and filter, signal conditioning components, timing components and microcomputer control system. Tea color sorter is a special material removed using photoelectric technology by Harmonia, photoelectric system analysis of tea material surface appearance and color, to distinguish tea, tea stalk and non inclusion, can solve the routine use of screening and winnowing and sorting tick equipment can not reach the tea stalk separation effect. Each tank has 2 high resolution camera hardware, data processing and, in the material passed through from both sides of the examination, to determine the amount of light reflected light to color, and the projection measurement of photoelectric sensor, and compared with the reference color reflected light, the difference signal amplification processing, when the signal is greater than a predetermined value. The driving spray system (nozzle trough end) with compressed air blowing heterochromatic material.
