Rice Color Sorter China Factory

Rice Color Sorter China Factory

Shijiazhuang Xinlu Technology Co., Ltd. is proud to present its Rice Color Sorter, engineered and manufactured in our China factory to deliver precise optical separation for rice processors. Designed for integration into both polishing and packaging lines, this machine ensures removal of discolored, chalky, or otherwise defective kernels, safeguarding the visual quality and market value of milled rice.

Working Principle
The Rice Color Sorter employs high-resolution cameras coupled with LED lighting arrays to capture detailed images of individual rice grains as they pass through a narrow inspection channel. Advanced image-processing algorithms analyze each grain’s hue, brightness, and shape, comparing these parameters against adjustable thresholds. When a kernel falls outside acceptable ranges, a rapid-response air nozzle ejects the undesirable grain into a separate collection hopper, while acceptable grains continue along the main product stream.

Key Features

• Multi-angle Lighting System: Uniform illumination from top and side LEDs minimizes shadows and enhances defect detection.

• High-speed Cameras: Capable of inspecting up to 120,000 kernels per second, ensuring throughput capacities of 8–12 t/h.

• Modular Ejection Valves: Individually controlled nozzles deliver targeted air bursts without disturbing adjacent grains.

• Recipe Management: Operators can store and recall sorting profiles for different rice varieties, including long-grain, medium-grain, and aromatic types.

• Touchscreen Interface: Intuitive HMI allows real-time monitoring of rejection rates, throughput, and system diagnostics.

Operational Benefits
By removing discolored and broken kernels, the Rice Color Sorter reduces manual rework and enhances the uniform appearance of the final product. Processors report lower customer complaints related to appearance defects and smoother downstream packaging operations. The ability to fine-tune sorting parameters also permits targeting specific defects—such as chalkiness, yellow kernels, or fissures—without discarding healthy grains.

Installation and Integration
This sorter is designed for seamless integration after the rotary polisher or gravity separator. Its compact footprint (approximately 2 m × 1 m) allows installation in existing processing lines with minimal civil works. Infeed and discharge conveyors are height-adjustable to match upstream and downstream equipment.

Maintenance and Support
Routine maintenance includes cleaning camera lenses, inspecting air valves for wear, and verifying the alignment of light panels. Shijiazhuang Xinlu Technology Co., Ltd. provides a complete spare-parts package, detailed maintenance manuals, and on-site training sessions. Our factory acceptance tests ensure that each unit meets performance criteria before shipment.
