A grain sorter machine is a device that utilizes optoelectronic technology to automatically separate off-colored items, inferior-quality products, or impurities from a large volume of material based on differences in color, shape, and other characteristics. It acts like a pair of “high-speed, intelligent eyes and hands” for the material, capable of instantly identifying and rejecting particles that “look different.” Get factory prices!

Optical Color Sorting Machine Technology

Multispectral Confocal Technology

This technology enables the rejection of transparent glass, desiccant, and off-color plastics, while supporting powerful yellow-sorting and reverse-sorting functions. It achieves effective impurity removal while reducing air consumption by approximately 20%.

LED Parallel Collimation Technology

Features high brightness, low heat generation, energy efficiency, and a long lifespan, ensuring optimal optical performance during operation.

Dust Removal Control Technology

Keeps the equipment surface and optical system clean, guaranteeing precise sorting even at high throughput rates.

Autonomous Computational Processing and Super-Brain Intelligent Recognition

The grain sorter automatically corrects optical errors and image distortion, enabling adaptive color-sorting computations. It accurately identifies materials regardless of variations in particle size, shape, or color.

Intelligent Magnetic-Control High-Frequency Solenoid Valve

This design replaces traditional pneumatic return mechanisms, ensuring zero internal or external airflow leakage. The use of superconducting magnetic technology, combined with advanced startup control and current-limiting techniques, reduces power consumption by approximately 70%.

Operating System

Users can freely select and define parameters—such as color, shape, size, and defect area—to specify the types of materials to be rejected.

Intelligent Light Source Control System

This system adjusts brightness based on material characteristics and ambient lighting conditions, ensuring optimal performance during the color-sorting process.

FAQ

How do you use a color sorter?

Use the machine’s camera to capture images of the material to be processed—specifically, two images of good samples and two of defective ones. The machine analyzes and learns from these images to classify the material. The equipment features 64 channels and 64 air nozzles; valves are used to blow away the defective material.

Can materials of different sizes be screened?

Yes. By equipping the machine with precision screens, you can sort for the desired sizes.
