Air Burst Sorting

Short answer: Optical sorters feed items along a belt or chute past cameras or sensors that judge color, shape or material. When an item matches the rejection rule, a precisely timed burst from an air jet knocks it into a separate stream.

The method is used in recycling, food processing and mining. The footage shows mixed recyclables being sorted by air jets.

Video transcript: Air Burst Sorting: Cameras Spot an Item and a Puff of Air Knocks It Aside

Did you know, pressurized air sorting is a technique used to separate materials based on their size, weight, or composition by directing controlled bursts of air of the items. It is commonly employed in recycling facilities, food processing, and industrial production lines. The process involves speeding materials onto a conveyor or into a shoot, where sensors or cameras identify specific items based on pre-programmed criteria, such as weight, shape, or material type. Once an item is detected, a high-pressure air nozzle precisely targets and ejects it into a designated bin or stream, separating it from the rest of the material. NOW YOU KNOW!
