APEX NIR CCD Dual Optical Nut Sorter Chute Type for Almond Cashew

APEX Optical Nut Sorter Features

The Model N vertical nut color sorter is professional sorting equipment specially developed for quality grading and purification of nut products. Equipped with a dual inspection system combining single-view infrared penetration technology and high-definition color CCD visual recognition, the unit carries out synchronous detection for both external shell appearance and internal kernel conditions, solving the defect of single-layer surface inspection brought by conventional universal grain color sorters.

1. Dual Testing for External Shell & Internal Kernel Quality

The color CCD module identifies exterior flaws including burnt marks, uneven coloration and surface stains on nut shells. Meanwhile, single-view infrared rays penetrate hard husk structures to precisely detect internal hollow kernels, deteriorated nut flesh and worm-infested particles, achieving full-range all-round quality screening for finished nuts.

2. Strong Compatibility with Mainstream Commercial Nut Varieties

This equipment fits precision sorting work for widely processed nuts such as almonds, pistachios, pine nuts and pecans, matching the demands of mass primary impurity removal and hierarchical sorting in regular nut processing lines.

3. Anti-interference Design for Long-term Stable Industrial Operation

Optimized optical algorithm configuration delivers outstanding anti-disturbance performance amid complicated on-site production conditions. The machine sustains steady sorting precision during prolonged continuous operation, perfectly fitting the economical and practical production layout of small and medium nut processing manufacturers.

As a high cost-performance professional sorting solution exclusively for nuts, Model N accomplishes standardized impurity separation and automatic grade sorting for bulk nut materials, significantly elevating the overall commercial grade and market value of finished nut goods.

Working Principle-How does it work?

Working Principle of Model N Nut Special Color Sorting System

Step-by-Step Sorting Workflow:

1. Raw mixed nuts containing deteriorated kernels, hollow nuts and shell residues are poured into the top feeding hopper.
2. The feeding vibrator uniformly distributes nut materials, enabling nuts to slide down the streamlined chute and maintain a stable single-particle free-falling posture.
3. Supported by dedicated light sources, matched high-definition CCD cameras and infrared penetration sensors collect data synchronously. CCD devices record surface features such as burnt shells and stained nut surfaces, while infrared rays penetrate hard nut shells to capture internal hidden defects.
4. The special dual-signal processor analyzes collected visual pictures and infrared spectral data in real time, and distinguishes qualified nuts from defective products according to preset nut quality thresholds.
5. Once defective nuts are identified, the system immediately sends execution signals to the nozzle assembly. Compressed air blows unqualified nuts into the rejected product hopper.
6. High-quality intact nuts fall into the accepted product hopper by natural gravity, completing the full automatic dual-inspection sorting process for hard-shell nuts.

Applicable Sorting Materials

The Model N dedicated nut color sorter is built with matched CCD appearance inspection plus infrared penetration detection system, which is professionally tuned targeting the physical characteristics of hard-shell nuts and high-oil nut kernels. It supports full-process purification and quality grading for mainstream commercial nut varieties, solving the hidden quality hazards such as internal rancidity, hollow kernels and worm-eaten flesh that ordinary grain sorting equipment cannot detect.

Covered mainstream processing nuts

1. Hard-shell tree nuts: Walnuts, almonds, pistachios, pecans, macadamia nuts, pine nuts and cashews
2. Processed nut raw materials: Shelled nut kernels, broken nut fragments, roasted semi-finished nut products

Core sorting targets for these nuts

• CCD visual inspection: Remove burnt husks, stained shells, discolored kernels, mildewed surfaces and foreign mixed impurities
• Infrared penetration scanning: Screen out hollow kernels, internally deteriorated flesh, rancid nuts and insect-damaged kernels sealed inside intact nut shells

Designed exclusively for the nut deep-processing industry, Model N realizes both exterior appearance screening and internal kernel health detection in one single device, meeting the raw material quality control requirements for nut roasting, packaged snacks and nut gift box production lines.
