| Contract Metric | Standard Specification | Contract Implication |
|---|---|---|
| Shell-Fragment Defect | Maximum 0.05% cap | Prevents customer rejections and machine jams |
| Kernel Moisture Content | 5% to 8% | Eliminates mold growth and avoids kernel brittleness |
| Safety Verification | Third-party COA | Confirms non-detectable aflatoxin levels before shipment |
Advanced Optical Sorting and Defect Removal
Modern processing plants utilize multi-layered optical sorting equipment equipped with CCD cameras and NIR spectroscopy. This high-speed technology processes up to 10 metric tons per hour with over 99.5% accuracy.
Automated optical sorting achieves a kernel net selection rate up to 99.6% after shell-breaking, cutting customer rejection rates by 30% compared to manual processing.
These advanced optical systems instantly remove discolored pieces, shell bits, and foreign objects.
Vacuum Packaging and Moisture-Proof Logistics
High-oil kernels react quickly to oxygen and ambient humidity. Chinese processing facilities use high-barrier polyethylene (PE) and polypropylene (PP) vacuum packaging to lock in natural flavor. Vacuum-sealed bags eliminate ambient oxygen to prevent lipid oxidation and rancidity. Sealed corrugated boxes with UV-protective coatings keep your shipment fresh during long sea transit.
