Colour sorter
open-in-new
<p>Color sorters or color sorters (sometimes called <a href="/facts/Optical_sorting/DmELpwkd">optical sorters</a>, digital sorters, or electronic color sorters) are machines used on production lines in bulk food processing and other industries. They sort items by color, detecting passing items' colors and using mechanical or pneumatic devices to divert items with colors outside the acceptable range or to create distinct groups. </p>
