Legende H 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 H 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.
