Legende HAD Series AI-Driven Sorting System

The core sorting challenge for cashew kernels lies in the high-precision interception of defects and foreign material. Any missed scorched kernels, moldy kernels, or foreign matter will directly compromise the quality baseline of the entire batch. Therefore, the core mission of the sorting equipment is to achieve efficient "pass/fail" binary judgment, maximizing the removal of defective products.

The Legende HAD Series is an intelligent vision-based sorting system tailored for this exact scenario. Equipped with 4-view cross high-resolution RGB (HR-RGB) VIS imaging technology and proprietary AI deep learning algorithms, the system performs real-time scanning and surface feature analysis on cashew kernels. Paired with high-performance air ejectors, the equipment rapidly identifies and precisely rejects scorched kernels, moldy kernels, foreign material, and undersized kernels within milliseconds, significantly improving the purity of the outgoing cashew kernels.

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 cashew processors build a robust quality defense, effectively safeguarding yield rates and processing profitability.
