Cashew kernels present a sorting challenge that goes far beyond simple defect removal — every good kernel carries significant commercial value, and its grade directly determines which market it serves. From premium whole kernels graded to export standards such as W240 and W320, to scorched or broken pieces destined for lower-value applications, the difference between profit and lost revenue often comes down to precision sorting. For processors operating in one of the world's most grade-sensitive commodity markets, intelligent vision-based sorting is the key to optimally allocating every kernel to its highest-value destination.
The Legende HAD Series is an intelligent vision-based sorting system custom-designed for cashew kernel industrial sorting and quality control. Leveraging innovative 4-view-cross-optic high-resolution RGB (HR-RGB) imaging technology powered by proprietary AI algorithms, the system delivers high-precision detection and removal of surface defects, grades kernels to export standards (W240/W320), and simultaneously eliminates scorched kernels and contaminants in the post-roasting stage — ensuring consistent, premium-grade output at every pass.
AI-driven surface defect recognition algorithms — trained on real-world production data using deep learning, with sorting precision refined continuously — ensure consistently high sorting accuracy across diverse kernel conditions and grades — helping processors maximize the value of every kernel, reduce costly misgrading, and deliver export-quality cashews with unmatched confidence.
Applications
Technical Features
● Custom-Designed Optical Sorting System for Cashew Kernels
✦ Compact dual-belt sorting system with designs for quick-install and simultaneous re-sorting of the accept from the primary sorting
✩ Primary sorting occurs on higher-level belt and rejects obvious bad kernels (rotten, shriveled, foreign material)
✩ Secondary sorting on lower-level belt receives accepts from primary sorting for sub-classification into multiple premium grades based on size, color and defect tolerance
✦ High-capacity vibratory feeding system evenly distributes cashew kernels into a single layer to minimize overlapping
✦ Sealed scanning/control enclosures provides machine with high-level dust protection
✦ Food-grade stainless steel structure and quick belt change ensures convenient routine maintenance and cleaning, meeting higher food safety and hygiene standards
✦ Integrated Dust Control System maintains high operation reliability and performance consistency, and minimizes downtime
✦ Available in two models with belt widths of 600 mm and 1200 mm, enabling processors to select the throughput capacity that best fits their production requirements
● AI Powered 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.
✦ In-House 4-View Crossed High-Resolution RGB Camera System provides 360° coverage, capturing high-definition imagery from multiple angles to detect abdominal spots, residual skin, discoloration, and shape irregularities.
✦ High-Intensity LED Illumination System Delivers bright, uniform, and stable lighting with low heat output and long service life, ensuring consistent image quality at high throughput.
✦ Market-leading high-precision detection of various detects in cashew kernels based on surface features:
