Cashew kernels are among the most grade-sensitive commodities in the global food trade — every kernel carries significant commercial value, and its classification directly determines which market it serves. From premium whole kernels to broken pieces and scorched fragments, the difference between top-tier export revenue and lower-value applications often comes down to sorting precision. For processors operating in this highly competitive market, intelligent vision-based sorting is the key to optimally allocating every kernel to its highest-value destination — not just removing defects, but unlocking the full commercial potential of every batch.
The Demeter B Series is an intelligent vision-based sorting system custom-designed for cashew kernel industrial grading and quality control. Featuring 360° on-roller inspection and multi-array (4 or 8) sorting through high-resolution RGB (HR-RGB) imaging technology powered by proprietary AI algorithms, the system delivers up to 16 distinct grade classifications based on color, size, shape, and surface defects in a single pass — maximizing processing efficiency without compromising sorting precision.
AI-driven surface defect recognition algorithms — trained on real-world production data using deep learning, with sorting precision refined continuously — ensure consistently high classification accuracy across diverse kernel conditions — helping processors maximize the value of every kernel, minimize costly misgrading, and deliver export-quality cashews with unmatched confidence.
Applications
Technical Features
● Custom-Designed Optical Grading System for Premium Cashew Kernel Processors
✦ Engineered exclusively for cashew kernels, tailored rollers optimize both anti-breakage performance and processing capacity
✦ Conveyor roller system performs individual scanning and analysis of each cashew kernel for defect detection and real-time classification of good-quality cashew kernels into multiple premium grades during a single pass through the grading machine
✦ High-capacity feeding system ensures uniform and stable cashew kernel distribution, precisely positioning each kernel onto the roller sorting system to eliminate inspection interference while maintaining grading accuracy
● AI Powered Ultra-High-Precision Defect Inspection System
✦ Proprietary AI algorithms enhance defect detection, with models retrainable on real-world production data via deep learning, enabling continuous refinement of sorting precision.
✦ High-Resolution Area-Scan Camera System captures high-definition imagery of each kernel as it passes over the rollers, enabling precise detection of discoloration, spots, residual skin, and shape defects for accurate grading.
✦ Ring Lighting Shadow-Free Illumination System delivers uniform, shadow-free lighting from all directions, eliminating dark spots caused by kernel contours and roller gaps — ensuring consistent image quality for reliable defect detection.
