Legende HSF Series AI HSI Sorting System

Single-belt models tailored for fresh blueberry sorting. AI-driven HSI-based system detects and removes soft, dehydrated, defective berries and foreign materials, with deep-learning–refined precision.

Blueberries present a sorting challenge that conventional optical systems cannot fully address — defects such as internal bruising, hidden mold, and moisture anomalies are often invisible to standard RGB cameras and the human eye alike. For processors supplying premium fresh, IQF, and export markets, these undetectable risks pose serious threats to product quality, shelf life, and brand trust. Intelligent, multi-spectral sorting is the key to seeing what conventional technology simply cannot.


The Legende HSF Series is a multi-spectral sorting system custom-designed for premium blueberries. Leveraging the seamless integration of cutting-edge hyper-spectral imaging (HSI) and high-resolution RGB (HR-RGB) imaging technology powered by proprietary AI algorithms, the system enables non-destructive evaluation of both surface and internal quality — going far beyond the capabilities of traditional RGB systems to detect defects that are invisible to conventional vision-based 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 — helping processors eliminate hidden quality risks, maximize usable yield, and deliver premium-grade blueberries with unmatched confidence.
