Legende HDF Series AI Optical Sorting System

The appearance quality of fresh vegetables directly determines their market value, yet traditional manual picking faces severe challenges. Highly dependent on workers' experience, attention, and physical condition, manual sorting suffers from visual fatigue during long shifts, significantly increasing missed detection rates. This makes it difficult to effectively intercept defects such as rotten leaves, discolorations, and insect damage.

The Legende HDF Series is an intelligent vision-based sorting system tailored for this exact scenario. Utilizing high-resolution RGB (HR-RGB) VIS imaging and proprietary AI deep learning algorithms, it scans and analyzes surface features of fresh vegetables. Coupled with high-performance air ejectors, the system achieves high-precision rejection of discolorations, surface blemishes, and foreign material within milliseconds.

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 fresh vegetable processing plants significantly reduce labor dependency, strengthen quality control, and effectively safeguard product purity and profitability.
