In the global trade and deep-processing supply chain of cashew kernels, precision grading is not merely a baseline for food safety, but a critical determinant of commercial value and the key to meeting diverse application scenarios. However, traditional sorting methods exhibit significant limitations in actual production: physical sieves can only perform rough grading based on particle size, failing to identify differences in appearance quality; manual sorting is not only inefficient but highly susceptible to worker fatigue and subjective judgment discrepancies, leading to quality inspection standard drift; intelligent belt-type vision-based sorting systems primarily focus on removing defective products and foreign material to ensure food safety and basic appearance, with their sorting logic largely confined to a binary "pass/fail" judgment, lacking the capability for multi-dimensional, precision grading of cashew kernels.
The Demeter C Series is an intelligent vision-based grading system tailored for this exact scenario. Featuring 360° inspection and a multi-array (4 or 8 groups) roller-type sorting structure, the system deeply integrates hyperspectral imaging (HSI) and high-resolution RGB (HR-RGB) VIS imaging technologies. Leveraging proprietary AI deep learning algorithms for real-time scanning and surface feature analysis on cashew kernels, and paired with high-performance air ejectors, it achieves precision classification into up to 16 grades in a single pass, strictly adhering to international trade standards for cashew kernels. This significantly enhances sorting efficiency while maintaining exceptional grading accuracy.
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 kernel processors consistently deliver high-quality products that meet stringent international standards, securing a competitive edge in the fiercely competitive global market.
