April 22, 2026

Recently, Xingtai Zhongde Intelligent Technology Co., Ltd. has achieved a major technological breakthrough in the field of rice processing with its latest "Zhongde" photoelectric color sorter. This equipment, leveraging its exceptional sorting accuracy and stable operational performance, has successfully addressed industry pain points such as the difficulty in thoroughly removing broken rice, discolored grains, glass, stones, and other impurities in traditional rice processing. It provides strong technical support for enhancing domestic grain safety and quality.

Technological Innovation: Deep Integration of Multi-Spectral Recognition and Intelligent Algorithms

The newly launched Zhongde rice color sorter incorporates the company's self-developed fourth-generation "Zhitong" multi-spectral recognition system. This system can simultaneously capture the reflection and transmission spectral information of materials in visible light, near-infrared, and specific wavelength bands, accurately constructing a full-dimensional optical fingerprint for each grain of rice. Even for impurities with similar colors but different compositions (such as deteriorated rice grains and normal ones), the system can achieve millisecond-level recognition by detecting spectral differences in their internal structures.

Compared to traditional color sorters, the "Deep Sea" AI learning model integrated into this equipment is a standout feature. Through deep learning from millions of sample images of various impurities, this model continuously self-optimizes its sorting logic. In practical production, it can not only identify known impurities but also intelligently detect and sort atypical defects such as abnormal shapes or localized mildew, significantly reducing both missed and erroneous selection rates.

Exceptional Performance: High Efficiency, Stability, and Energy Savings

In terms of capacity, this model can handle up to 12 tons per hour per channel, meeting the large-scale production needs of medium and large rice mills. Its high-precision ejection valve system, with a response time shortened to 0.1 milliseconds, delivers precise and adjustable air jets. This ensures efficient impurity removal while minimizing the loss of valuable raw materials. The industry-leading "good-to-bad ejection ratio" is controlled within 1:1.2, directly boosting economic benefits for users.

The equipment also excels in stability and user-friendliness. Core optical components are equipped with fully sealed, constant-temperature, and constant-humidity protective chambers, along with automatic cleaning devices, ensuring long-term recognition accuracy even in dusty processing environments. The new touch-control interface is simple and intuitive, featuring preset sorting programs for various materials that allow for one-click switching, greatly reducing operator training costs and technical barriers. Furthermore, the modular design of the entire machine enables key maintenance to be completed within 15 minutes, effectively ensuring production continuity.

Application Value: Safeguarding "Food Safety on the Tip of the Tongue" from the Source

For rice processing enterprises, the application value of the Zhongde color sorter extends far beyond improving appearance. Its ability to accurately remove hazardous materials such as aflatoxin-contaminated grains, glass, and metal fragments physically prevents harmful substances from entering downstream products. This strictly ensures the hygiene and safety of finished grain, helping companies meet increasingly stringent national food safety standards while building strong market credibility.

Feedback from a customer in North China: "After adopting Zhongde equipment, impurity content in our finished rice has been consistently maintained within the national premium standard, and customer complaints have dropped by over 90%. The energy-saving performance of the equipment is also outstanding, reducing electricity consumption by approximately 18% compared to the old equipment."

Industry Outlook: Empowering Modern Agriculture with Intelligent Sorting Technology

The General Manager of Xingtai Zhongde Intelligent Technology Co., Ltd. stated: "Food security is of paramount national importance. We remain dedicated to in-depth research and development of intelligent sorting technology. Our technology platform has already been successfully extended to sorting millet, beans, tea leaves, nuts, and various Chinese medicinal materials, beyond just rice. In the future, we will continue to deepen our efforts in agricultural products and resource recycling fields. Through more intelligent and reliable 'Zhongde' series sorting equipment, we aim to support the precision and intelligent upgrading of China's processing and manufacturing industries, creating sustained value for global customers."

The launch of this rice color sorter once again demonstrates the innovative strength and industry leadership of Xingtai Zhongde Intelligent Technology Co., Ltd. in the field of intelligent sorting equipment. It also injects new technological momentum into the quality revolution of the grain processing industry in China and globally.
