Legende H Series AI Optical Sorting System

Single-belt models tailored for nuts and dried fruit sorting. AI-driven RGB-camera-based system targets and removes visible defects and foreign materials, with deep-learning-refined sorting precision.


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, discoloration, and foreign materials 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 to pre-sort nuts and dried fruit and protect both product quality and processing efficiency from the very first step. Leveraging high-resolution RGB (HR-RGB) imaging technology powered by proprietary AI algorithms, the system precisely detects and removes color variations, visible defects, and foreign materials in real time, improving finished-product consistency, and providing a more efficient, reliable and quantifiable solution for nuts and dried fruit pre-sorting.


AI-driven surface defect recognition algorithms — trained on real-world production data using deep learning, with sorting precision refined continuously — ensure high sorting accuracy across a diverse range of nuts and dried fruit — helping processors enhance product quality, increase throughput, reduce labor costs, and improve overall product quality from the earliest stage of production.
