Camera of a Color Sorting Machine: The Core of Optical Sorting Technology

07-02-2026

In modern color sorter machines, the camera is the most critical component that determines sorting accuracy, speed, and overall performance. Acting as the “eyes” of the machine, the camera captures high-resolution images of materials in real time and enables precise separation based on color, shape, size, and surface characteristics.

For industries such as food processing, agriculture, plastics, minerals, and recycling, advanced camera systems are what make optical color sorting machines reliable, efficient, and highly accurate.

What Is the Camera in a Color Sorting Machine?

The camera in a color sorting machine is a high-speed industrial vision system designed to inspect thousands of objects per second. Unlike ordinary cameras, these systems are built for:

• Continuous high-speed inspection
• Precise color and defect detection
• Stable performance in industrial environments

When combined with controlled LED lighting and intelligent software, the camera detects even minute variations that are impossible to identify through manual inspection.

Types of Cameras Used in Color Sorting Machines

1. CCD Cameras (Charge-Coupled Device)

CCD cameras are widely used in color sorter machines due to their excellent image clarity, high color accuracy, and low noise levels. They are especially effective for sorting applications that demand precise color differentiation, such as rice, wheat, pulses, and seeds.

2. RGB Cameras

RGB cameras analyze objects based on red, green, and blue color values. These cameras are ideal for standard color sorting applications where visual appearance is the primary sorting parameter. They are commonly used in food grains, nuts, and dry fruits processing.

3. Infrared (IR) Cameras

Infrared cameras play a crucial role in advanced color sorting applications. Unlike visible-light cameras, IR cameras detect differences in material properties beyond surface color. They are highly effective for:

• Detecting foreign materials
• Sorting plastics and polymers
• Identifying impurities with similar visual color
• Improving sorting accuracy in challenging conditions

Infrared camera technology significantly enhances the performance of AI-based color sorter machines, especially in recycling and industrial material sorting.

How the Camera Works in a Color Sorting Machine

1. Material Feeding – Raw material flows evenly through chutes or conveyor belts.
2. Image Capture – High-speed CCD, RGB, and IR cameras capture detailed images.
3. Image Processing – Intelligent software analyzes color, shape, size, and material properties.
4. Decision Making – The system instantly classifies acceptable and defective items.
5. Ejection – High-precision air ejectors remove unwanted material.

This complete process takes place within milliseconds, ensuring high throughput with exceptional accuracy.
