    AI Overview
    AI-enabled Near-Infrared (NIR) Sorting System Enhances ...
    An infrared optical sorting machine uses near-infrared (NIR) light to analyze the unique chemical fingerprints of materials, allowing it to automatically identify and separate different substances (like plastics, metals, or food products) based on their molecular composition, even distinguishing between similar-looking items or black plastics, leading to higher purity in recycling and manufacturing. These systems use sensors to detect specific wavelengths reflected by materials, then use air jets or mechanical arms to eject the desired or undesired items with high speed and accuracy. 
    How it works 
    • Light Emission: The machine shines NIR light (invisible to humans, 760-2500 nm) onto a stream of singulated materials (on a conveyor or in freefall).
    • Reflection & Absorption: Different materials absorb and reflect these wavelengths uniquely, revealing their chemical makeup (e.g., PET, HDPE, PVC).
    • Sensor Detection: High-resolution cameras or sensors capture these reflected patterns.
    • Ejection: Sophisticated software interprets the data, and pneumatic ejectors or robotic arms quickly remove the identified material from the stream. 
    Key applications 
    • Recycling: Separating mixed plastics (PET, HDPE, PVC), paper, cardboard, wood, and even metals.
    • Food Processing: Sorting grains, nuts, seeds, and other food products for quality control.
    • Waste Management: Removing contaminants from construction & demolition (C&D) debris. 
    Advantages 
    • Accuracy: Identifies materials by chemical composition, not just color.
    • Efficiency: High throughput for large volumes of material.
    • Versatility: Can be configured for various materials and upgraded to adapt to market changes.
    • Black Plastic Sorting: Advanced NIR sensors can effectively sort black plastics (like ABS, PS, PVC) that are invisible to traditional color sorters.
