Hazelnut color sorters represent a specialized segment of optical sorting technology designed to handle different types and grades of hazelnuts, including natural, blanched, and roasted varieties. These machines employ advanced optical sorting technology that can accurately identify and remove defective hazelnuts based on color variations and physical characteristics. The technology is particularly effective at detecting dark, discolored, shriveled, and rotten hazelnuts, along with foreign materials such as shells, wood chips, and twigs.

The sorting process begins with hazelnuts entering the machine through a vibrating feed system, then passing through a detection zone where high-resolution cameras scan each nut multiple times. When defects are identified, precise air jets activate to eject the substandard nuts from the production line. This process ensures that only premium-quality hazelnuts continue to packaging, maintaining the highest standards of product excellence.

Modern hazelnut color sorters feature user-friendly operating platforms that simplify operation and reduce the need for extensive training. With intelligent algorithm systems, these machines can adapt to natural variations in hazelnut appearance while consistently identifying true defects. This balance between sensitivity and specificity is crucial for maintaining high throughput without compromising sorting accuracy
