The core of the color sorter is the recognition system, and the core of the recognition system is the sensor. The color selection machine has at least 5388 high sensitivity optical imaging sensors, equipped with high-performance digital chips, which can sample the rice flow on both sides. Even small foreign objects can be completely distinguished. The color sorter can effectively identify small impurities as small as 0.04 mm. The principle is that the optical camera can convert moving rice into 256 level color images. The full digital analysis device and advanced graphic recognition technology can instantly identify moldy wheat and clean it from the rice pile.
When the color sorter entered China, it was mainly used for large heavy industry ore dressing, plastic dressing, quartz sand dressing and so on in the early days. Later, it entered the grain field to select rice, peanuts, melon seeds, tea, soybeans, coffee, salt and so on. The color sorter was first used to select diamonds, which is very popular in Britain and the United States. It is said that because color sorting machines are much more expensive than other grain processing equipment, general grain enterprises are unwilling to spend this money.
Excessive humidity in the environment can lead to mold, insect damage, and disease in rice. If these harmful rice that has not been thoroughly cleaned are mixed into the rice pile, it can affect the quality of the rice in light cases and endanger human health in severe cases. Once the rice becomes moldy and inedible, it can cause liver damage and symptoms of poisoning in the human body. Mouldy rice contains nitrite, which is not conducive to physical health and is prone to cancer, especially the occurrence of malignant tumors in the liver.
Mouldy rice can also produce Aspergillus flavus, which is a strong carcinogen. Moreover, aflatoxin cannot be washed away and cannot be removed by boiling at high temperature. It is difficult to degrade in the body, and accumulating a certain amount in the body can lead to the occurrence of cancer. Symptoms of aflatoxin poisoning include fever, abdominal pain, vomiting, loss of appetite, etc. It is one of the main risk factors for inducing liver cancer. There may be lesions in the liver, and after 2-3 months, liver enlargement, liver pain, jaundice, splenomegaly, ascites, lower limb edema, and abnormal liver function may also be accompanied by heart enlargement, pulmonary edema, and even spasms, coma, etc. Most patients may experience rectal, liver, and gastric bleeding in the late stage. Aflatoxin is very toxic, about 68 times as toxic as arsenic. If you eat too much at a time, you will die easily. If you take a small amount of it for a long time, it will easily lead to cancer, especially increase the incidence rate of liver cancer.
Once the rice enters the factory, it is all being reduced, including stones, rotten ropes, iron nails, and moldy rice, until all become clean rice. After undergoing numerous trials and tribulations, a grain of rice needs to undergo 17 more painful tests such as peeling to become a product recognized by the color selection machine.
