M coloring machine refers to rice plant used in the production of refined rice color machine, mainly used for the selected disease spot with yellow and black rice, in a foreign country has a history of several decades, rice plant in China using color separator is after the reform and opening up. Wheat color separator is flour in the flour processing high precision when used, is mainly used to remove black impurity in the wheat and mildew, black embryo wheat, its history is very short, is developed by our country's scientific and technical personnel in 2001, the first surface of jin yuan industry co., LTD. 1000 t in zhengzhou is used in the flour. And m coloring machine production is relatively small, the reason is that the rice contains yellow disease spot and black spot disease spot larger proportion of grain, generally in 5% ~ 5%; The output of wheat color separator is bigger, because the color machine installed in the last procedure before grinding wheat into, wheat after a cleanup and secondary cleaning, around 90% of the black impurities (including organic and inorganic impurities impurities) has been removed, the rest of the black impurity accounts for only a few parts per thousand of total MaiLiu (if mildew grain, black grain percentage increase is another kind of circumstance). M coloring machine production of each channel is 50 ~ 100 kg, the output of wheat coloring machine each channel can reach 150 ~ 250 kg. Also 1 96 channel separator of color, can deal with rice about 6 t/h, processing the wheat can be up to 12 ~ 15 t/h. The color of separator are quoted above configuration CCD sensor identification system, if the configuration of traditional sensor identification system effect is much worse. Therefore, when choosing color separator for processing object and its impurity must first clear, otherwise, cannot achieve expected effect.
