Laser sorters are used for applications that require both colour and structure sorting, like raisins, shrimps, vegetables, fruit, tobacco and nuts.
The product is spread by a shaker onto a high-speed conveyor belt. The cameras are positioned above the center of the belt or at the end on a reference roller and scan the products when they pass.
These cameras (each strategically located) detect discoloration on or in between the products. Each camera sends its data to a powerful computer where it is then processed.
The machines can be equipped with monochromatic and / or full color cameras. Number of cameras depending on the resolution which needs to be seen.
When defects are detected (intensity and size parameters may be adjusted by touch screen), air nozzles at the outfeed are activated at exactly the right moment based on signals from the shaft encoder and CPU.
These nozzles blow the defect or unwanted product away just as it begins its ballistics. The air nozzles are fast and accurate.
