Technology Optimization of Nut Color Sorter for Nuts from Different Origins
2025-08-27Nuts from different origins vary significantly in color, shape, and defect types, posing challenges to traditional Color Sorter systems. To address this, the latest Nut Color Sorter has undergone targeted technology optimization, becoming a core tool for nut processors worldwide—complementing specialized equipment like Rice Color Sorter and Grain Color Sorter in the food sorting industry.
For example, almonds from California (USA) often have subtle yellowish spots, while those from Australia tend to have darker hull residues. The optimized Optical Sorter in Nut Color Sorter uses multi-spectral imaging to capture these tiny differences, with AI algorithms trained on origin-specific datasets to distinguish normal nuts from defective ones with 99.8% accuracy. For walnuts from Iran, which are prone to internal mold (hard to detect visually), the Color Sorting Machine integrates near-infrared (NIR) detection modules—identifying moldy kernels without damaging the nuts, a function that even advanced Bean Color Sorter models rarely include.
Shape adaptation is another key optimization. Brazilian cashews have irregular curved shapes, while Vietnamese cashews are more uniform. The Nut Color Sorter adjusts its sorting valve speed and conveyor belt tilt in real time via sensor feedback, ensuring no intact cashews are rejected due to shape differences. This flexibility surpasses that of standard Tea Color Sorter models, which are designed for more consistent leaf shapes.
Moreover, the Nut Color Sorter supports custom origin profiles. Users can store parameter settings for nuts from specific regions (e.g., Turkish hazelnuts, Chilean pistachios) in the Color Sorting Machine system, enabling one-click switching between sorting tasks. This reduces setup time by 50% compared to traditional Optical Sorter equipment that requires manual parameter recalibration.
These optimizations not only improve nut product quality but also expand the application scope of Color Sorter technology. Whether sorting large Brazil nuts or small pine nuts, the upgraded Nut Color Sorter delivers stable performance, helping processors meet global market quality standards.
