Legende H Series AI-Driven Sorting System

Nuts and dried fruit present a unique sorting challenge: high-value raw materials arrive with a wide range of visible defects, including shell fragments, mold, discolorations, and foreign material such as stones, sticks, or processing debris. Sorting these contaminants at an early stage is critical: missed defects carry costly consequences downstream, while over-rejection erodes valuable yield.

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 nuts and dries fruit, 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. It enables nuts and dried fruit processors build a strong quality defense from the earliest stage of production, effectively ensuring product purity and processing profitability.
