Materials of construction must compatible with processed materials, especially in food and pharmaceutical applications.

Optical Sorters

Optical sorting technology represents the cutting edge of separation equipment. These systems use cameras, lasers, or near-infrared sensors to identify materials based on color, shape, or chemical composition. Advanced software algorithms then trigger air jets or mechanical diverters to separate identified materials.

Key Applications:
– Plastic recycling identification
– Food quality sorting
– Mineral processing
– Electronic waste recycling
– Packaging material separation

Technical Considerations:
Resolution, processing speed, and detection capabilities vary significantly between systems. Near-infrared (NIR) sorters can identify material composition, while color cameras sort based on visual characteristics. Throughput rates can reach several tons per hour with modern high-speed systems.
