    Key Takeaways

    • RaymanTech's AI optical sorter improves kidney bean quality by removing defective beans, ensuring only high-quality products are packaged.

    • The sorter increases efficiency by processing 10-15 tons of beans per hour, significantly reducing labor costs and time compared to manual sorting.

    • Advanced X-ray inspection detects hidden contaminants, enhancing food safety and ensuring a clean product for consumers.

    Kidney Bean Sorter Challenges

    Kidney Bean Sorter Challenges

    Defective Bean Issues

    Traditional sorting methods often struggle to remove all types of defective beans. These defects can include splits, mudball beans, mold, and beans with off-odors. The table below shows common issues found in kidney bean processing:

    Type of Damage

    Description

    Whole, split, or broken beans

    Sprouted, immature, perforated, or discolored by weather or disease.

    Mudball beans

    Beans covered in soil, considered dockage.

    Splits

    Split beans and broken pieces.

    Magnesium spot

    Black spot inside the bean, often in cranberry beans.

    Odour

    Unpleasant smells that lower quality.

    Heated beans

    Dull seed coats and dark color, showing damage.

    Rotted beans

    Spongy beans in advanced decay.

    Mouldy beans

    Exterior or interior mold growth.

    A kidney bean sorter with advanced optical technology can detect and remove these defective beans, including those that are discolored, damaged, or immature. This ensures a clean and high-quality product for both red and white kidney beans.

    Color and Size Sorting

    Uniformity in color and size is important for market value and consumer satisfaction. Manual sorting often fails to meet industry standards. The following table outlines key requirements:

    Metric

    Requirement

    Size (count per pound)

    Defined count per pound

    Moisture content

    Less than 12%

    Uniformity index

    At least 90%

    Color consistency

    Must meet ISO 17859 standards

    A modern kidney bean sorter uses cameras and AI to sort beans by color and size, achieving consistent results that meet these standards.

    Contaminant Detection

    Contaminants such as metals, glass, and plastics pose serious health risks. Manual sorting cannot reliably detect these hazards. The table below lists some dangerous contaminants and their effects:

    Contaminant

    Health Effects

    Lead (Pb)

    Cognitive impairment, developmental delays, nervous system disorders

    Cadmium (Cd)

    Kidney damage, osteoporosis, lung cancer

    Arsenic (As)

    Skin lesions, cardiovascular diseases, increased cancer risk

    Mercury (Hg)

    Neurological symptoms, developmental issues, cognitive impairments

    RaymanTech’s comprehensive approach, which includes X-ray inspection, helps detect and remove even micro-impurities and hidden contaminants, improving food safety.

    Efficiency and Labor

    Manual sorting is slow and labor-intensive. Automated systems, such as the kidney bean sorter, can process much larger volumes. For example, high-capacity industrial systems can handle 10-15 tons per hour, while manual or budget-friendly systems manage only 1-2 tons per hour. Automation increases efficiency, reduces labor costs, and ensures consistent quality.

    RaymanTech Sorter Solutions

    AI Optical Sorting Technology

    RaymanTech uses advanced AI Deep Learning algorithms in its kidney bean sorter. These algorithms recognize complex defect patterns and distinguish between naturally variegated beans and damaged ones. The system captures detailed images using multi-beam imaging and high-resolution cameras. It analyzes the shape, color, and texture of each bean in real time. This process identifies subtle defects that traditional optical sensors may miss. The kidney bean sorter removes discolored, damaged, or immature beans, ensuring a consistent product for both red and white kidney beans.

    Note: The AI optical sorter can sort beans by multiple grades in a single pass. This feature helps producers separate products based on quality levels efficiently.

    • The technology ensures only clean, uniform, and high-quality beans are selected for packaging.

    • It improves sorting accuracy and reduces waste.

    X-Ray Inspection System

    RaymanTech’s X-ray inspection system uses AI-driven technology to identify internal defects and foreign materials in kidney beans. The system detects issues that are not visible externally. It finds foreign objects that share similar color and shape with the beans. This ensures a comprehensive inspection process.

    The X-ray inspection system can identify both metallic and non-metallic contaminants. These include glass, ceramic, stone, bone, hard rubber, and hard plastic. It is effective for inspecting various products, including canned goods and high-salinity foods. The kidney bean sorter uses X-ray sorting to provide assurance against high-density foreign materials. It ejects contaminants such as metal fragments, glass shards, stones, dense rocks, high-density plastics, and rubber.

    Double Layer Conveyor

    The AI Standard Double Layer Optical Sorter features a unique double-layer conveyor system. This design allows for a two-stage sorting process. The first layer removes larger impurities and defective beans. The second layer targets micro-impurities such as hair, fine strings, and tiny contaminants. The belt speed ranges from 150 to 180 meters per minute, supporting high-capacity production.

    • The double-layer conveyor increases throughput and maintains high output quality.

    • It operates reliably in high-dust environments and handles challenging product types, including wet, sticky, or frozen materials.

    High Capacity and Adaptability

    RaymanTech’s kidney bean sorter is engineered for high capacity and adaptability. It processes large volumes of beans quickly and efficiently. The system handles various bean types, including kidney beans, black beans, pinto beans, chickpeas, and soybeans. Each type has unique characteristics, and the sorter adapts to meet specific needs.
