Legende HWFT Series AI-Driven Sorting System

Every carrot is different, but your customers expect the same high standard, every time. In carrot processing, sorting accuracy directly determines yield, product quality, and profitability. Yet whole-carrot sorting presents a unique challenge: unlike small, randomly scattered produce, whole carrots require full-surface scanning, and conventional single-mode inspection easily creates blind spots, leading to missed defects or false rejects.

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 full-surface scanning and analysis on every carrot, 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 carrot processors dramatically reduce labor dependency, consistently deliver batches with extremely low defect rates, and significantly boost both product quality and processing efficiency.
