Rice is a finished product made from rice grain after cleaning, hulling, milling, finishing and many other processes. The reporter recently went to the Spring Eagle rice industry interview, the process of rice processing also have some understanding. Let us understand the rice production out of an important gate - color sorter.

The principle of color sorter

The heart of the color sorter is the recognition system, the core of the recognition system is the sensor. Color sorter has at least 5388 high sensitivity optical imaging sensors, sensors equipped with high-performance digital chip, can be sampled on both sides of the rice stream. Even subtle foreign matter can be completely distinguished. The color sorter can effectively identify tiny impurities as small as 0.04mm. The principle is that the optical camera can convert rice in motion into a 256-level color picture, and the all-digital analytical device and advanced graphic recognition technology will instantly identify and clean it out of the rice pile.

Development of Color Sorter

Color picker was first born in foreign countries, the United States, the United Kingdom since the 20th century, 30 ~ 40 years on the development of color picker, until the 1980s, foreign color picking technology began to surge forward. China is even later, began after the rapid progress of foreign countries, but the Chinese people are very smart, from the start to take off only less than 10 years to do the foreigners half a century of work. Grain, oil and food industry" statistics show that in 2010 the global demand for color sorters is 27,000 units, China accounted for 13,000 units, almost half of the total global demand. Because the color sorter than other grain processing equipment to be much more expensive, the general grain companies do not want to spend the money.

Application of color sorter

The environment is too humid will lead to rice mold and insect pests, diseases, these failed to thoroughly clean up the harmful rice if mixed into the rice pile, the lesser will affect the quality of rice, the more serious will be harmful to human health. Once the rice mold, not to eat, otherwise it will cause liver damage, human poisoning symptoms. Moldy rice contains nitrite, which is not good for health. Moldy rice will also produce Aspergillus flavus, is a strong carcinogen, and aflatoxin one can not be washed off, the second by boiling at high temperatures can not be removed. In the body is difficult to degrade, in the body to accumulate to a certain amount, it will lead to cancer!
