Dehydrated vegetables present a unique sorting challenge: the drying process fundamentally alters the material's color, texture, and appearance, making it extremely difficult to distinguish surface defects from natural color variations. Foreign material such as stones, stalks, burnt fragments, and processing residues can be nearly indistinguishable from the product itself. Relying on manual inspection in such complex conditions is not only inefficient but also prone to missed defects due to visual fatigue, resulting in inconsistent quality that cannot meet the demands of modern processing.
The Legende H Series is an intelligent vision-based sorting system tailored for this exact scenario. Powered by high-resolution RGB (HR-RGB) VIS imaging and proprietary AI deep learning algorithms, the system performs real-time scanning and surface feature analysis on dehydrated vegetables, and paired with high-performance air ejectors, achieves millisecond-level precision rejection of discolorations, surface blemishes, and foreign material.
Empowered by AI-driven surface feature recognition, the system continuously learns from real production data, steadily improving its detection accuracy. This means the equipment's performance is not static after deployment; instead, it continuously adapts and improves as production data accumulates, delivering stable and reliable sorting performance. This enables dehydrated vegetable processors dramatically reduce labor dependency, consistently deliver batches with extremely low defect rates, and significantly boost both product quality and processing efficiency.
