The Expert in Sorting All Categories of Grains, Safeguarding the First Line of Food Safety
This Grain Color Sorter is a high-precision intelligent sorting equipment specifically designed for the modern grain processing industry. Utilizing advanced optical imaging and intelligent algorithm technology, it enables high-speed, non-destructive, and refined sorting of various grains such as rice, wheat, corn, sorghum, oats, and buckwheat. It accurately removes discolored grains, moldy grains, insect-damaged grains, stones, glass, and various other impurities. It is a core piece of equipment for improving grain commodity grades, ensuring food safety, and achieving automated and intelligent production.
Core Value: Purification and Impurity Removal, Safety Assurance, Efficiency Multiplication, Value Enhancement.
Multi-Spectral Fusion Imaging: Integrates high-resolution color CCD, Near-Infrared (NIR), and specific band optical technologies. It can not only accurately identify surface color and shape differences but also detect internal quality defects such as mold, sprouting, and yellowing.
AI Algorithm Matrix: Built-in deep learning models tailored to the physical characteristics of different grains. It can adaptively recognize ergot in wheat, germ defects in corn, color variations in sorghum, etc. The sorting strategy becomes more precise with use.
Ultra-High-Speed Computing Platform: Equipped with dedicated image processing chips, achieving recognition and sorting decisions for over 120,000 grains per second, ensuring high throughput without missing any defects.
Heavy-Duty Industrial Design: The body uses thickened steel plates and a reinforced structure to withstand harsh production environments with high dust and continuous operation, ensuring long-term stable performance.
Premium Core Components: Key optical components, pneumatic ejection valves, and control systems utilize internationally renowned brands, offering long lifespan, high reliability, and low maintenance costs.
Efficient Dust Prevention: Built-in multi-stage air filtration and positive pressure dust-proof systems effectively protect optical components from dust contamination, ensuring consistent imaging clarity.
One-Touch Intelligent Operation: A large-size touchscreen with a graphical interface allows for simple and intuitive parameter presets and recalls. Changing materials for production requires no complex adjustments.
Data Management: Displays and records key production data such as output, good product rate, and rejection rate in real-time. Supports report export, providing a basis for production management and quality traceability.
Modular Maintenance Design: Major functional modules support quick disassembly and assembly, facilitating cleaning, maintenance, and part replacement, minimizing downtime.
Precise Ejection Technology: Utilizes high-frequency solenoid valves and airflow control algorithms to achieve millisecond-level precise ejection. It efficiently removes impurities while significantly reducing the carry-over of good product, minimizing waste.
Energy-Efficient Design: Optimized air circuit and overall energy consumption provide excellent energy consumption per unit output, reducing long-term operational costs.
