Nuts sorting faces a challenge that RGB-camera-based system struggles to overcome: shells and foreign material are highly similar to good products in both color and appearance. Relying solely on VIS imaging makes it difficult to distinguish them, posing a serious quality and brand threat to processors serving high-end retail, confectionery, and foodservice markets.
The Monarch VGN Series is a dual-sensor sorting system tailored for this exact scenario. Through the deep integration of dual-band InGaAs-SWIR (Short-Wave Infrared) imaging and high-resolution RGB (HR-RGB) VIS imaging, the system combines internal chemical composition analysis with surface feature recognition, extending its detection capabilities far beyond single VIS imaging. Specifically, the SWIR imaging efficiently identifies shells and foreign material that are visually indistinguishable from good products and undetectable by VIS imaging, while the VIS imaging handles the detection of discolorations and surface blemishes. Paired with high-performance air ejectors, the system achieves millisecond-level precision rejection of defects and contaminants.
By leveraging the complementary advantages of dual-sensor imaging, the system effectively addresses the persistent challenge of same-color contaminants that RGB-camera-based equipment struggles to detect. It enables nuts processors to consistently deliver low-defect batches, ensuring product quality, food safety, and compliance with stringent industry and export standards, thereby safeguarding brand reputation.
