Color sorter is not only an industrial equipment, but also hides many interesting details related to life and technology, breaking the impression of "mechanical=boring".
1, The secret of 'fiery eyes and golden eyes': not just looking at color
The "vision" of color sorting machines far exceeds that of humans, and their recognition dimensions are particularly rich, not just simply distinguishing between "red, yellow, and green".
Being able to see through the "inner" of materials: Near infrared color sorting machines can penetrate the surface of particles, such as detecting peanuts with normal appearance but moldy inside, or hollow melon seeds, which are completely impossible for human eyes to do.
Can recognize "invisible differences": For materials such as plastic particles, it can capture subtle differences in grayscale and glossiness that are difficult for humans to detect, such as distinguishing between recycled and new materials, with an error controlled at 0.01mm level.
Fast to "blurry" speed: The camera of high-end color sorting machines can take tens of thousands of photos per second, equivalent to completing nearly 10 "blink" visual captures in 1 second, ensuring that materials transported at high speeds will not be missed.
2, Binding to life: everything you eat and use goes through it
The birth of many everyday items cannot be separated from color selection machines, but you may not have noticed it.
Eating: The Wuchang rice you bought does not contain yellow rice or broken rice, it is the result of screening by a beige color sorting machine; The pistachios in supermarkets do not have empty shells or bad fruits, and they are also pre selected by color selection machines.
Used: Plastic particles for mobile phone cases and positive electrode material particles for new energy batteries are screened by a color sorter before production to remove impurities and ensure stable quality of the final product.
Special scenario: Even the traditional Chinese medicine industry uses color sorting machines, such as screening moldy particles in goji berries and red dates, which are more efficient and hygienic than manual selection.
3, The 'evolutionary history' is very interesting: from 'monochrome' to 'AI intelligence'
The technological iteration of color sorting machines is full of ingenuity and becoming increasingly "smart".
Early 'monochrome era': can only recognize single color differences, such as only removing black impurities from rice, helpless against yellow rice with similar colors.
Mid term 'multi-color era': capable of recognizing multiple colors such as red, green, blue, etc. simultaneously, able to distinguish particles of different shades of different colors, and applicable to beans and nuts.
In the current era of AI intelligence, combined with machine learning, it is possible to autonomously "learn" the characteristics of different materials, such as the same batch of plastic particles. Even if there is a slight color deviation, it can accurately determine whether it is a qualified material, and automatically adjust screening parameters to reduce manual intervention.
