Comprehensively analyze the working principle of grain color sorter

Manufacturers of coarse grain color sorters can be divided into one-way and two-way detection structures, and can be divided into primary selection and secondary selection from the perspective of technology. Most of the old color sorters use one-way detection, which only observes the materials from one direction. Particles with disease spots on the back or particles covered when materials overlap cannot be detected and are missed. Therefore, it is not perfect in principle. The carry out ratio refers to the ratio of the quantity of impurities in the waste selected by the color sorter to the normal rice or wheat grains. The level of the carry out ratio can be set, which is generally about 1.3~1.5. If the carry out ratio is set too high, the selection rate and processing capacity will be affected; If it is set too low, the selected waste contains too many normal rice or wheat grains, which will cause waste. If it is reprocessed, a certain amount of manpower and material resources will be required, which will cause a lot of trouble and economic losses.

The whole process mechanization promotion was launched in an all-round way. The Ministry of Agriculture has deployed and carried out the whole process mechanization promotion action for the production of major crops, focusing on the mechanization of major crops, major production regions and major production links, and accelerating the popularization and application of mature whole process mechanization production technology for major grain crops with the goal of continuous demonstration and upgrading the level; With the goal of breaking the bottleneck and exploring the mode, we will demonstrate and promote the whole process mechanized production technology of economic crops such as cotton, oil and sugar. In 2015, China's agricultural machinery purchase subsidy policy reform and innovation also achieved new results. Further reduce the scope of subsidized machines and tools, focus on subsidizing machines and tools needed in key links of grain, cotton, oil and sugar crop production, select machines and tools in key and weak links to implement open subsidies, decouple the qualification of subsidized machines and tools from the support and promotion directory, and promote "purchase machines first, then apply for subsidies" and "one-stop" management services.
