Legende HWFT Series AI-Driven Sorting System

Tailored single-belt model for French fries sorting. Powered by AI-driven high-resolution VIS imaging and high-performance air ejectors, the system integrates consecutive top-view and off-belt parabolic detection to more efficiently identify and reject defects that conventional sorters struggle to handle, delivering deep-learning–refined sorting precision.

In French fries processing, even minor discolorations, surface blemishes, or shape irregularities can compromise product consistency and damage brand reputation. Relying on manual inspection alone is not only too slow to keep up with high-speed production lines, but also prone to missed defects due to visual fatigue, resulting in inconsistent quality that simply cannot match the pace of modern processing.


The Legende HWFT Series is an intelligent vision-based sorting system tailored for this exact scenario. It features a unique dual-mode detection architecture of belt top-view inspection combined with off-belt parabolic detection, powered by high-resolution RGB (HR-RGB) VIS imaging and proprietary AI deep learning algorithms. The system performs real-time scanning and surface feature analysis on every French fries, and paired with high-performance air ejectors, achieves millisecond-level precision rejection of discolorations, surface blemishes, shape irregularities, and foreign material.


Empowered by AI-driven surface feature recognition, the system continuously learns from real production data, steadily improving its detection accuracy. This means the equipment's performance is not static after deployment; instead, it continuously adapts and improves as production data accumulates, delivering stable and reliable sorting performance. This enables French fries processors dramatically reduce labor dependency, consistently deliver batches with extremely low defect rates, and significantly boost both product quality and processing efficiency.
