Legende HD Series AI Optical Sorting System

Dehydrated vegetables present a distinct sorting challenge — the drying process alters color, texture, and appearance, making it difficult to distinguish defects from natural variation. Foreign materials such as stones, stalks, burnt fragments, or processing debris can be nearly indistinguishable from the product itself, posing serious risks to food safety and brand reputation. For processors supplying premium retail, foodservice, and ingredient markets, ensuring product purity and visual consistency is not optional — it is a prerequisite for customer trust and regulatory compliance.

The Legende HD Series is an intelligent vision-based sorting system tailored for dehydrated vegetables industrial grading and quality control. Leveraging high-resolution RGB (HR-RGB) imaging technology powered by proprietary AI algorithms, the system precisely identifies and removes color variations, surface defects, and foreign materials in real time, improving finished-product consistency, ensuring compliance with food safety regulations, and providing a more efficient, reliable and quantifiable solution for dehydrated vegetables 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 dehydrated vegetables — helping processors enhance product quality, increase throughput, reduce labor costs, and maintain a competitive edge in the market.

Applications

Technical Features

● Tailored Superior Optical Sorting System for Dehydrated Vegetables

✦ 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

✦ Optional innovative high-capacity 2-layer vibratory feeding system evenly distributes dehydrated vegetables 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

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