Legende HD Series AI Optical 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, 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 HD 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.

Applications

Technical Features

● Tailored Optical Sorting System for Pre-Sorting Nuts and Dried Fruit

✦ Compact dual-belt sorting system with quick-install and simultaneous re-sorting design

✩ Primary sorting occurs on higher-level belt and aggressively removes all potential defects (may include false rejects)

✩ Secondary sorting on lower-level belt receives rejects from primary sorting for false-reject recovery

✦ High-capacity vibratory feeding system evenly distributes nuts and dried fruit into a single layer to minimize overlapping

✦ Food-grade stainless steel structure complies with global food safety and hygiene standards

✦ Sealed scanning/control enclosures provides machine with high-level dust protection

✦ Integrated Dust Control System maintains high operation reliability and performance consistency, and minimizes downtime

✦ Quick belt change for convenient routine maintenance and cleaning, meeting higher food safety and hygiene standards

✦ Available in two models with belt widths of 600 mm and 1200 mm, enabling processors to select the throughput capacity that best fits their production requirements

● AI Powered High-Precision Defect Inspection System

✦ Proprietary AI algorithms enhance defect detection, with models retrainable on real-world production data via deep learning, enabling continuous refinement of sorting precision

✦ High-Resolution RGB Camera System captures detailed surface imagery, replacing traditional manual sorting
