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, discoloration, and insect damage.

The Legende HDF Series is an intelligent machine-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 color variations, surface defects, and foreign material within milliseconds.

Empowered by AI-driven surface feature recognition algorithms, the system can conduct deep learning training based on real production data, continuously optimizing the visible defect detection accuracy. This means the equipment’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 help fresh vegetable processing plants significantly reduce labor dependency, fortify quality defense lines, and effectively guarantee product purity and processing profits.
