Hefei Yijiete Optoelectronic Technology Co., Ltd (YJT), located in Hefei China, is a high-tech Enterprise specialized in R&D, manufacture and sale of products integrated with Optics, Electronics and Machinery. YJT commits itself to research and development of optoelectronic color sorter which utilizes special opto-source like infrared ray and ultraviolet radiation, intelligent color sorter and CCD color sorter for the best solutions of sorting purpose, YJT has successfully developed YJT color sorter series with continuous effort of all 150 professional staff members. The brand-new YJT color sorter series are hi-tech products designed and developed after researching similar products home and abroad. The YJT series use the optoeclectronic principle and utilizes the latest DSP(Digital Signal Processor) technology instead of traditional industry control computer system and fussy logic arithmetic and SVM(Support Vector Sorter) arithmetic. With double viewing mirrors and capacity of secondary sorting for precise sorting work, YJT color sorters has reserved the functions of primary sorting machines and the channels for primary sorting or secondary sorting can be freely set. The state-of-the-art design of optoelectronic sensor and computer-controlled system in addition to the high-speed electromagnetic mechanism have been adopted in the machine, and also the color display and touch screen have been installed therein, it can be said that YJT color sorter completely realizes automatic control mode, the sorting accuracy and the convenient operation mode are prior to similar products.
