Color sorters with InGaAs

CI Infrared Nuts Series

CI Infrared Nuts Series are specialized optical sorters with infrared (InGaAs) technology, designed primarily for precise sorting of nuts and other food products. They are ideal for nuts (almonds, walnuts, pistachios), separating shells, inner partitions/membranes, minor damage, and atrophied/shriveled kernels. They are also suitable for seeds, coffee, and spices where infrared analysis is required to detect structural differences.

CI Infrared Nuts Series details

The CI Infrared Nuts Series uses an advanced HD imaging system with CCD cameras and slow-shutter technology (50,000 scans/s), enabling detection of defects as small as 0.0025 mm². A high-speed ejection system (up to 1,200 ejections/s) separates shells from kernels, unripe nuts, and contaminants without damaging the product.

The MEYER CI Infrared Nuts Series (CI) sorter is a versatile, multi-purpose device designed for precise sorting of nuts, grains, and seeds. It handles a wide range of materials, with particularly high effectiveness for nuts such as pine nuts, pecans, pistachios, and other challenging products. The machine offers a broad range of configuration options across three models—120CI, 240CI, and 360CI—allowing its functionality to be precisely tailored to the capacity requirements of each production facility. The sorter effectively removes shells, damaged and shriveled kernels, moldy and discolored products, as well as foreign materials including sticks, stones, plastics, and glass. Thanks to its InGaAs composite infrared system and advanced detection technologies, the MEYER CI Infrared Nuts Series (CI) identifies density variations and differences in chemical composition that challenge traditional color sorters. This enables the critical separation of nut shells from kernels even when they have similar colors.

  • InGaAs Composite Infrared System: Uses advanced infrared technology to analyze material density and composition. The intelligent system automatically recognizes and removes shells, moldy grains, and contaminants such as ergot, ensuring effective separation of unwanted fractions that traditional color sorters cannot detect.
  • Digital Electrical Control System: A topological architecture reduces redundant control modules by 45% and enables hidden cable routing. This solution eliminates the risk of sudden failures of key components at the source and guarantees stable, reliable operation.
  • High-Frequency Vibrator: A compact high-frequency vibration motor ensures high efficiency and a more stable material drop, supporting optimal inspection and detection.
  • Intelligent Vacuum Technologies: The system features Upper & Front Vacuum extraction, effectively filtering light drift fractions, dust, and other impurities at the feed and discharge ends, ensuring a cleaner material stream and improved sorting performance.

AI Powered System

MEYER thoroughly researches AI technology to provide the best sorting solutions. Our devices ar equipped with deep learning AI systems, based on the analysis and integration of data features such as color and shape. By comparing materials with an extensive library of models, Meyer ensures precise classification even of the smallest defects at the level od 1-2 pixels.

Ultra high-speed HD Imaging System

The advanced inspection system scans material at a speed of 50,000 times per second, capturing its movement in slow motion—up to 1,000 times slower than in real time. The super slow-motion technology enables precise reconstruction of the material’s actual parameters, significantly enhancing sorting efficiency. The use of low-distortion lenses and an industrial-grade CCD sensor allows for the identification of objects as small as 0.0025 mm². This exceptional precision ensures unparalleled sorting accuracy, even for the smallest defects and impurities.

Maglev Ejectors®

Developed, manufactured, and patented by MEYER, Maglev® 3.0 ejectors deliver exceptionally fast response times and precise ejection. With their non-contact (levitating) design, Maglev® ejectors operate at a high frequency exceeding 1200 Hz. The millisecond-level opening and closing of the flaps significantly reduce material losses. The standardized design and fully automated production ensure longer service life and easier maintenance of the device.

Innovative Vision Systems

MEYER machines are equipped with high-resolution cameras, enabling the identification of material characteristics based on multiple aspects such as color, shape, density, and type of material. The minimum recognition range can reach as small as 0.0004 mm². MEYER sorters feature a multispectral identification system, including visible light, infrared light, UV light, and X-RAY technology. By utilizing differences in material properties, the cameras in MEYER machines allow for the precise removal of defects and foreign objects.

Full Spectrum Lighting System

The lighting, similar to natural daylight, reveals the true color of the material, allowing even the subtlest shades to be detected. The lighting in MEYER sorters, based on a full RGB range, is designed to precisely reveal the actual colors of materials. With the ability to adjust the background color, the system further enhances material feature detection depending on its specific properties. This solution enables more precise analysis and improves the efficiency of identifying defects and contaminants.

Remote control and service support

MEYER software enables remote control of devices and real-time monitoring of key machine parameters. Thanks to artificial intelligence-based technology, the system also offers remote machine start-up, backup creation, and intelligent status checks. The ability to remotely diagnose issues and manage machines from anywhere ensures convenience and efficiency in daily operation.

Sniper System

Utilizes advanced technology to detect contaminants in the material with high precision. Through three-dimensional reconstruction and a high-speed HD imaging system, it accurately locates the center of contamination. This data enables precise removal of defective units.

Simplified Interface

The control panel in MEYER devices is designed for maximum intuitiveness, making machine operation easy at any skill level. With a clear layout and user-friendly design, the system ensures convenience and operational efficiency. After proper training by the MEYER service team, operators can fully utilize the machine's capabilities while minimizing the time required for configuration and adjustments.
