Sprinkle cumin, chili peppers and other spices on the kebabs, diners in the taste of delicious barbecue, may not have thought, on the good edible spices behind also hides an important segmentation track - color sorting machine.

In a color sorter company in Hefei, 36 Krypton Anhui saw different colors of cumin were placed in separate storage boxes, accurate and efficient sorting is amazing.

"Hefei, Anhui Province is not only the domestic color sorter capital, but also the global color sorter capital." A long-term deep plowing color sorter track told 36 Krypton Anhui.

In a list of color sorters, nine of the top ten are Hefei companies, of which Meiya Optoelectronics has the largest color sorter production base in Asia.

In the domestic important manufacturing exhibition, science and technology exchanges, as well as grain and oil products technology fairs, Hefei made color sorter have become the focus of attention, Hefei's color sorter why is the development of such a rapid?

Can be divided into food can also be divided into ore

Color sorter, according to the difference in the optical properties of the material, the use of photoelectric detection technology will be particulate material in the different color particles automatically sorted out of the equipment.

Jason learned that the color sorter is mainly divided into material supply system, photoelectric system, electronic control system, sorting system, four parts, of which the "photoelectric system" is the core part of the color sorter, mainly by the light source, the background plate, sensors, and other devices, the light source illuminated to the measured material will produce different reflective properties, the background plate to provide a reference signal, the reflective properties and the equivalent of qualified products. Its reflective properties are equivalent to qualified products, while defective products will be fed back to the electronic control system for the next step.

"You can imagine the color sorter as a person, the photoelectric system is equivalent to the human eye, which is used to observe the object, and when a defective product is seen, it will be blown out with a spray valve." The above industry insiders told 36 Krypton Anhui so image.

In fact, the color sorter is also an imported product.

In the 1980s, because the grain needs to be screened by machine to improve the quality and efficiency, the country began to introduce the rice color sorter, the brand is mainly Japan's Anzai and Toyo and the UK's Sotex and other brands.

In the 1990s, the country began to study the manufacturing technology of color sorter, in 1994, the Institute of Physical and Chemical Engineering of the Nuclear Industry developed MMS-24A color sorter, the color sorter to fill the gaps in the development and production of the domestic color sorter. 2000, the Anhui enterprise Meiya photoelectric development of digital double-sided color sorter, the model broke the monopoly of foreign brands in one fell swoop on the situation of the domestic market.

In the media reports, color sorter is generally categorized into agricultural equipment manufacturing enterprises.36 Krypton Anhui noted that the color sorter can not only sort rice, wheat and other food crops, but also sorting ores, glass, plastics, etc., the range is very wide. Overall view of the agricultural field is still the main application market of China's color sorter, color sorter in the field of industrial materials and industrial products sorting popularity is still low, in the initial stage, has a greater market potential.

Data show that in 2021, China's color sorter production in 51,100 units or so, the same period of domestic exports of 9,724 units, imports of 20 units, the total domestic demand for 41,400 units.

Jason noted that the reason for the low import data is that the rise of domestic mainstream CCD color sorter squeezes the foreign high-end color sorter market, and the second is that many foreign color sorter enterprises have set up joint ventures or sole proprietorships in China.

More important reason is that the color sorter enterprises in Hefei occupied the main domestic market.

Hefei color sorter industry a standout

In a report of Hefei Daily this year, the relevant person in charge of Hefei Municipal Economic and Information Bureau said, "Hefei color sorter industry, a standout." From Hefei, 2022 Hefei color sorter enterprise revenue of nearly 4 billion yuan, accounting for 70% of the city's agricultural machinery and equipment manufacturing industry; from a national perspective, Hefei City, about 40 color sorter enterprises, the number of enterprises, the annual output accounted for nearly 80% of the country.

The reason why Hefei in the color selector track development so quickly, to be traced back to the United States of America photoelectric Anhui enterprises.

Suffering from the monopoly of foreign brands, Meiya photoelectric team in 1996 developed China's first rice color sorter with independent intellectual property rights, after 2000, the successive launch of digital color sorter (2004), color wide range of color sorter (2005), digital intelligent tea color sorter (2008), X-ray foreign body detection machine (2009), intelligent X-ray tire Automatic Inspection Machine (2011), Internet + Artificial Intelligence Color Sorter (2015), Multi-spectral Integrated Color Sorter (2020), and more than 10 new products to fill the gaps in China.

This also makes the color sorter become the cornerstone business of Meiya Optoelectronics, and the financial report of the first half of 2023 shows that Meiya Optoelectronics' color sorter revenue is about 560 million yuan, accounting for about 58% of the revenue.
