Recently, Xingtai Zhongde Intelligent Technology Co., Ltd. (hereinafter referred to as "Zhongde Intelligent") announced that its newly developed high-precision rice color sorter has been successfully deployed in multiple medium-sized rice enterprises. It achieves precise removal of impurities such as discolored grains, stones, and glass fragments from rice, with a sorting accuracy of up to 99.98%, bringing breakthrough progress for enterprises in improving product quality and production efficiency.

As domestic and international consumers' demands for food safety and quality continue to rise, the grain processing industry is facing a critical period of transformation and upgrading. Traditional manual sorting methods are not only inefficient and costly but also prone to missed inspections and misinspections due to visual fatigue, making it difficult to meet the needs of modern production. As a leading enterprise in the field of intelligent sorting equipment in China, Zhongde Intelligent, relying on years of technological accumulation, has deeply integrated artificial intelligence, multispectral recognition, and high-speed air jet technology to launch a new generation of rice color sorting solutions.

The newly launched rice color sorter adopts the company's self-developed "Lingtong" AI recognition system. Through high-resolution CCD sensors and multi-band spectral imaging technology, this system can accurately capture multi-dimensional features such as color, shape, and texture of rice grains at over 4,000 shots per second. The deep learning algorithm model built into the equipment, trained on more than 5 million sample images, can accurately distinguish normal rice grains, yellowed rice, moldy grains, immature grains, and various inorganic impurities. It also allows users to customize sorting standards according to their needs.

In the sorting execution stage, the equipment is configured with a 128-channel ultra-high-speed precision air valve array with a response time of less than 1 millisecond. This ensures defective particles are accurately ejected the moment rice grains pass through the identification zone, effectively avoiding the erroneous removal of qualified products. According to actual test data, the maximum single-machine processing capacity can reach 3.5 tons per hour, with energy consumption reduced by 15% compared to the previous generation, truly achieving high efficiency and energy savings.

"Our rice color sorter is not just a piece of equipment; it is a complete quality management solution," stated the Technical Director of Zhongde Intelligent. "In addition to basic impurity removal, the system can also perform fine sorting functions such as grading rice by chalkiness and classifying by grain shape, helping customers enhance the added value of their products. Furthermore, the equipment possesses self-learning capabilities; the longer it runs, the more accurate the sorting model becomes, and the stronger its adaptability."

The successful application of this equipment not only addresses pain points for processing enterprises in quality control but also promotes the standardization and intelligentization of grain processing at the industry level. A person in charge of a rice enterprise in Northeast China that has adopted the equipment provided feedback: "After introducing the Zhongde color sorter, our premium product rate increased by nearly 8 percentage points, manual re-inspection costs decreased by 70%, and customer complaint rates significantly dropped. More importantly, the stable output of high quality has helped us build credibility in the high-end market."

In addition to its in-depth work in the field of rice sorting, Zhongde Intelligent's technology platform boasts strong scalability. Based on the same core technical architecture, through parameter adjustment and model training, sorting machine models suitable for various grains such as millet, mung beans, red beans, and sesame have been derived, achieving excellent results in mold detection and grading for nut products like peanuts, almonds, and walnuts. The company's R&D team is actively exploring the application potential of this technology in broader fields such as sorting traditional Chinese medicine slices, sorting plastic recycled pellets, and mineral pre-sorting.

Looking ahead, Zhongde Intelligent will continue to be driven by innovation, focusing on the in-depth research, development, and scenario expansion of intelligent sorting technology. The company plans to launch an IoT-integrated cloud management platform in the second quarter of this year, enabling remote monitoring, data analysis, and predictive maintenance for equipment groups, helping customers build transparent and digital smart factories.

Xingtai Zhongde Intelligent Technology Co., Ltd. is always committed to empowering traditional industries with cutting-edge technology. With the mission of "Precise Sorting, Creating Pure Value," it provides customers with reliable, efficient, and intelligent solutions, joining hands with global partners to stride into the new era of Industry 4.0.
