With the development trend of Chinese color selecting machine, the application scope of omni-grain selection machine is becoming more and more widespread


As the trend of the development of China's color separator is more and more mature, color separator in China is becoming more and more extensive application scope, application of enterprises more and more, since the earliest photoelectric intelligent color CCD color separator which has the function of secondary sorting opto-mechatronics gas in a body's high technology products, adopt the high speed high sensitivity 2048 pixel linear CCD sensor as the material color and shape, the FPGA + DSP architecture of data processing, optimization with automatic calibration of optical design and efficient image processing algorithms such as hardware and software architecture, to the minimum resolution, color accuracy, yield and the versatility of the machine is superior to the photoelectric color separator.

Today, the intelligent vision separation technology and its principle are similar to the visual judgment of human eyes, so it is called intelligent visual separation technology. When choosing lighting source generally measured normal material and defective material according to the spectral curve features (the reflected light and transmitted light, excitation fluorescence, etc.) or a similar combination design of normal material and defective material detection sorting spectral lines to strive to maximize contrast. Thus, the defects in the material are eliminated.

The maximum throughput of the channel is the maximum amount of processing per channel used to select the different colors of the polished rice. When the content of the chromatic grain in polished rice is less than or equal to 0.3%, its maximum channel yield is usually 80 ~ 100kg/h. If the surface of the rice grain is not bright or polished, it will affect the recognition effect of the optical element of the color selecting machine, thus reducing the maximum channel output of the color selection machine. If the content of the medium heterochromatic granule is 0.0.3%, the output of the largest channel of the color selection machine will be greatly reduced.

Therefore, in selecting the color selecting machine, we must fully consider the content of the heterochroma of rice, whether the rice is polished and the market is required for the appearance quality of finished rice. The practice shows that the content of the heterochromes in polished rice is between 0.3 and 0.5%, and the maximum channel yield is 40 ~ 80kg/h.

Due to decline in rice by chute into the color selection is thrown into by inertia, if the machine is not enough level, grain of rice in the chute by the friction of the size is different, the speed will change, grain running attitude will also change, these values will be different from the built-in numerical machine, which is difficult to get the best color effect.
