Color Sorter Series

Introduction

The rice color sorter offered by ANON is designed to quickly and accurately detect impurities, broken grains, and discolored kernels in rice, separating them to ensure clean, intact, and uniformly colored premium rice. This machine brings higher efficiency and added value to the rice processing industry.

Built with high-quality materials and precision manufacturing, the sorter offers excellent reliability, stability, and a long service life. In addition, it incorporates advanced energy-saving technology to reduce power consumption.

Working principle

The selected material enters the machine from the top hopper and moves downward along the channel through the vibration of the feeding device. As the material accelerates into the sorting chamber, it passes through the inspection area between the sensors and the background board. Under the illumination of the light source, variations in light intensity and color are detected, generating output signals that activate the ejector valves. The defective or discolored grains are blown into the waste hopper, while the good grains continue to fall into the finished product hopper, thus achieving accurate separation.

Features

1. High-Precision Automatic Sorting

The ANON Rice Color Sorter is equipped with a high-resolution camera system that integrates over 5,000 high-performance CCD image sensors with a sorting resolution of 0.1 mm. This allows it to detect even the smallest color variations on individual grains. Combined with multi-spectral recognition technology and custom-designed industrial lenses tailored for rice sorting, the system ensures every grain is perfectly imaged on the sensor. Optimized optical pathways further enhance accuracy. The machine is capable of sorting by color, shape, texture, and material, identifying impurities that are nearly impossible to detect with the naked eye, such as yellowed grains, moldy rice, discolored grains, and foreign matter. With a sorting accuracy of over 99%, it guarantees rice with a uniform color and flawless appearance, easily meeting the standards of premium-grade rice.

2. Enhancing Rice Market Value

Manual selection often suffers from fatigue, inconsistent eyesight, and fluctuating quality. In contrast, the ANON color sorter relies on intelligent algorithms based on the spectral characteristics and recognition features of rice. These algorithms are designed to balance sensitivity and robustness—detecting even subtle color differences while filtering out irrelevant surface variations—ensuring stable performance and consistent quality. After sorting, the rice grains are crystal-clear, bright, and uniform, allowing every batch to meet the same high standard. This enables the rice to be marketed directly as premium or gift-grade rice, enhancing brand reputation and trust. With the same raw materials, the selling price and market value of rice increase significantly after color sorting.

3. Ensuring Food Safety

Moldy rice may contain aflatoxin, a highly carcinogenic substance, and manual sorting can never completely eliminate it. In addition, impurities such as tiny shards of glass, if not thoroughly removed, can pose serious hazards. The ANON Rice Color Sorter effectively eliminates these safety risks, reducing the chance of food contamination and ensuring compliance with high food safety standards. This helps meet the growing consumer demand for healthy and safe food products.

4. High Efficiency, Low Operating Costs

The ANON color sorter integrates high-speed DSP digital image processing technology, enabling faster detection and higher recognition accuracy. Its main control system is powered by an ARM9 series advanced embedded processor chip, which improves both processing speed and sorting precision. The machine is also equipped with professional-grade high-speed air valves that deliver fast response times, low power consumption, and longer service life. Thanks to its modular structure, maintenance and repairs are easy and cost-effective, further reducing operational expenses while boosting efficiency.
The ANON Rice Color Sorter can process several tons of rice per hour, far surpassing the efficiency of manual sorting. This not only saves on labor costs but also guarantees consistent sorting quality that is unaffected by human fatigue. Beyond removing discolored grains, the machine can also effectively eliminate glass, desiccants, plastics, stones, husk fragments, and other impurities. With a single investment, it provides long-term savings in labor costs while ensuring superior product quality.

5. Easy Operation

The ANON Rice Color Sorter features a streamlined user interface for effortless operation and real-time monitoring. Equipped with an industrial-grade 10-inch color touchscreen, it allows for simple parameter settings and intuitive navigation. The colorful interface is not only user-friendly but also visually pleasing. No specialized technical knowledge is required for operation or maintenance. The machine adopts an intelligent closed-loop control system with an industrial-grade data bus, ensuring reliable communication and strong anti-interference capability. In addition, an intelligent fault alarm system helps operators quickly identify and resolve any issues. With smart temperature and air-pressure control, the machine is always maintained at optimal working conditions.

6. Adaptability to Complex Materials and Environments

With dual-side simultaneous detection and multiple working modes, the ANON sorter can meet diverse rice sorting requirements with exceptional versatility. It achieves high sorting precision with a low carryover ratio, making it suitable not only for rice but also for glutinous rice, beans, medicinal herbs, and even plastic granules. Designed to operate stably in dusty or high-temperature environments, it is an excellent fit for a wide range of processing scenarios.

FAQ

1. What are the two types of rice color sorter machines?

There are CCD (single-color color sorters) and RGB color sorters (multi-color color sorters). Single-color color sorters, as the name suggests, can only select one color, while multi-color color sorters can sort different colors according to different needs.

2. Is rice sorted by color?

Rice is usually categorized by its length, color, and processing method. For example, jasmine rice is a long-grain rice that comes in both milled (white rice) and unprocessed (brown rice).

3. How does an optical sorter operate?

First, the operator places the material into a hopper, where it is vibrated and moved down a chute. Then, a pneumatic or mechanical ejector separates the material based on size and quality, ejecting any defective material.

4. How should I maintain my color sorter on a daily basis?

Regularly clean the lens, spray valve, and passages to prevent dust from affecting detection accuracy. Check the spray valve operating pressure (0.2-0.5 MPa) and the air compressor pressure (≥0.7 MPa) to ensure stable air flow. Regularly clean or replace the air filter element to prevent air flow blockage.
