Monarch HWN Series AI-Driven Sorting System

Nut sorting faces a challenge that traditional VIS systems struggle 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 HWN Series is is an intelligent machine-vision-based 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, combined with proprietary AI deep learning algorithms, 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 conventional surface feature defects. Paired with high-performance air ejectors, the system achieves millisecond-level precision rejection of color variations, surface defects, and foreign material.

By leveraging the complementary advantages of dual-sensor imaging technology, the system effectively solves the persistent challenge of "same-color foreign material" that traditional equipment struggles to address. Empowered by AI-driven surface feature recognition algorithms trained on real production data through deep learning, the system continuously refines its visible defect detection accuracy over time. This means the machine's performance is not fixed at the time of factory shipment; instead, it continuously adjusts and improves with the accumulation of production data, delivering stable and reliable sorting performance to nut processors consistently deliver batches with extremely low defect rates, safeguarding brand reputation with reliable sorting performance, ensuring product quality and food safety, and meeting stringent industry and export standards.
