Wenyao Red Lentils Green Yellow Colored Peeled Split Lentils Lentils Sorting Machine Newest Model Multiple Sorting Color Sorter

A color sorter (also known as an optical sorter or digital sorter) is an automated machine used in industrial and agricultural production lines to separate bulk materials by their color, shape, or size. It uses high-resolution cameras and sensors to detect items outside a specific range and eject them with compressed air jets.

How It Works

• Feeding System: Materials are fed into the machine via a hopper and travel along a chute or conveyor belt, with a vibrator ensuring a uniform, single-layer flow.
• Optical Detection: As the material passes through an observation area, it is illuminated by a high-intensity light source (usually LEDs). High-resolution cameras (CCD or CMOS) capture real-time images and color data (RGB) of each item.
• Signal Processing: An embedded computer system processes the images using specialized algorithms, often enhanced with artificial intelligence (AI) and deep learning, to compare each item's characteristics against preset quality standards.
• Separation (Ejection): When a defective or unwanted particle is detected, the system sends a signal to a high-speed pneumatic ejector (air jet). The air jet blows the unwanted material into a separate collection channel, while the good material continues along the main flow

Applications

Color sorters are widely used across many industries to improve product quality, increase efficiency, and reduce labor costs.

• Agriculture and Food Processing: This is the primary application, including the sorting of:
  • Grains and Cereals: Rice, wheat, corn, barley, oats, and millet.
  • Pulses and Beans: Lentils, peas, soybeans, and various other beans.
  • Nuts and Seeds: Peanuts, walnuts, almonds, pistachios, coffee beans, sesame seeds, and sunflower seeds.
  • Other Food Items: Tea leaves, dried vegetables, and spices.
• Recycling: Color sorters are crucial in separating different types and colors of plastic flakes (PET, HDPE, PVC, etc.), granules, glass fragments, and other mixed waste materials for reuse.
• Mining and Diamond Industry: In mining, they are used to sort ore, minerals, and stones based on color or transparency.
• Other Industrial Uses: They can be used for sorting various other bulk materials such as salt, specific chemicals, or electronic waste components (e.g., printed circuit boards).

Color sorter work principle:

The working principle of CCD color sorter CCD digital camera to material is adopted signal acquisition.Analyze the collected signals, handling, comparison, to eliminate beyond the value of the material.
Color selection process as shown:

Color sorter at work,Feed hopper in the material under the action of vibrator is uniform distribution in each chute,The CCD signal of the whereabouts of the material in testing,If it is found that there are unqualified material or impurities in the material,The startup ejector to blow the defective goods in the hopper.(Above only for the working process of the diagram,The actual material shall prevail.)
