As we all know, the quality of rice is one of the indicators to measure the purchase of rice. Only when the quality of rice is good, without impurities, can consumers be encouraged to buy. There is no doubt that rice production enterprises are facing the challenge of 100% extinguishing of particles and impurities of different colors, such as cinders, small glass, black rice grains, etc. The rice color sorter can fully meet these requirements. However, when choosing a sorting machine, it will bring some doubts. How should we choose a suitable rice color sorter?

1. Purchase a color sorter with a color linear CCD sensor. The rice color sorter is aimed at the difference between yellow and black grain rice and normal white rice. There is no difference in general physical properties. It cannot be removed by conventional cleaning methods. Only the difference in color and reflectivity between yellow and black grain rice and white rice can be used. , use photoelectric colorimetric method and equipment to remove it, also known as photoelectric color sorter. Photoelectric sensors are the eyes of the color sorter. Commonly used photoelectric sensors include silicon photocells, black and white line arrays, color line array CCDs, etc. Considering the number of color selection categories and service life, choose a color sorter with color line array CCD sensors.

2. Select the model and size of the rice sorting machine according to the company's daily rice processing output. Under normal circumstances, the processing capacity of each channel is kg/hour. For example, if a color sorter with 128 channels is used, the daily processing capacity is more than 15 tons (8 hours/day). Considering small township enterprises and use efficiency, 128 to 192 can be selected. Color sorter for channels.

3. The color sorting accuracy and the take-out ratio of the rice color sorter are important indicators to measure the quality of the color sorter. In general, the color-selection accuracy is greater than that and the take-out ratio is less than 1:8. From the point of view of operation, the selection of touch-screen intelligent operating system can reduce the operator's learning and mastery of computer language. From the perspective of after-sales service, it is a better solution to choose the products of domestic enterprises with better qualifications. At present, the quality of color sorters produced by domestic enterprises is comparable to that of foreign brands, and there are after-sales service and professional maintenance centers. Convenience advantage.
