Legende HS Series AI Optical Sorting System

Blueberries present a sorting challenge defined by delicate fruit and diverse end markets — fresh berries destined for supermarket shelves must meet strict visual standards, IQF fruit must be free of stems, leaves, and underripe or overripe berries, and jam and juice production requires consistent raw material to ensure uniform flavor and color. For processors serving multiple market channels, intelligent vision-based sorting is the key to delivering the right quality to the right destination — cost-effectively, reliably, and at scale.

The Legende HS Series is an intelligent vision-based sorting system tailored for cost-effective supermarket and export-grade sorting of blueberries. Leveraging high-resolution RGB (HR-RGB) imaging technology and proprietary AI algorithms, the system handles fresh and IQF blueberry sorting as well as jam and juice production to identifies and removes color variations, surface defects, and foreign materials — improving finished-product consistency, and providing a more efficient, reliable, and quantifiable solution for blueberry sorting.

AI-driven surface defect recognition algorithms — trained on real-world production data using deep learning, with sorting precision refined continuously — ensure consistently high sorting accuracy across diverse blueberry conditions and end-use requirements — helping processors deliver premium-grade fresh and IQF blueberries, reduce costly rejections, and meet the exacting standards of supermarket and export markets with unmatched confidence.
