Zhongde Color Sorter Efficiently Removes Impurities from Peanuts, Boosting Quality Upgrade in Nut Industry
June 3, 2026 - Recently, Xingtai Zhongde Intelligent Technology Co., Ltd. successfully delivered a set of high-performance CCD intelligent color sorting equipment to a major domestic nut processing enterprise. Specifically designed for the precise removal of moldy kernels, discolored kernels, and inorganic impurities such as stones and glass fragments from peanut kernels, this advanced technology ensures food safety and enhances product grade, earning high praise from the client.
In the nut processing industry, especially for bulk commodities like peanuts, various impurities mixed into raw materials have long been a pain point affecting final product quality and production efficiency. Traditional manual sorting methods are not only inefficient and costly but also struggle to ensure consistency and stability. Xingtai Zhongde Intelligent Technology Co., Ltd. has deeply researched and developed optimized "Zhongde" series intelligent color sorting solutions tailored to address these industry-specific challenges.
The delivered color sorter is equipped with a self-developed multi-spectral recognition technology and a high-resolution CCD imaging system. This system can sensitively capture subtle color, shape and texture differences on peanut kernel surfaces. For common issues in peanuts such as aflatoxin contamination (manifesting as moldy black spots), immature kernels, broken red-skin kernels, as well as deleterious impurities with similar density or color to peanut kernels, the machine achieves rapid and accurate identification. Its core algorithm, trained on massive datasets of peanut samples, possesses strong self-learning and adaptive capabilities. It effectively reduces recognition errors caused by variations in material batches or moisture content, ensuring high sorting accuracy and a low ratio of good product loss even under high-speed operation (with a processing capacity reaching several tons per hour).
Beyond exceptional "vision," the equipment also excels in "execution." It employs a globally leading ultra-high-speed solenoid valve ejection system with microsecond-level response time, capable of precisely removing identified defective products and impurities. The loss rate of good product is remarkably low, directly enhancing the client's economic benefits. The overall structure of the equipment uses food-grade stainless steel, complies with hygiene standards, and is easy to clean and maintain. The user interface is user-friendly, allowing flexible and straightforward parameter adjustment to easily adapt to the sorting requirements of different grades and varieties of peanuts.
During the installation and debugging process, project engineers from Xingtai Zhongde Intelligent Technology Co., Ltd. provided comprehensive and systematic training to the client's operators, ensuring the equipment delivers optimal performance. The client's production manager feedback: "The deployment of this Zhongde color sorter has completely transformed our pre-processing stage. The purity of the sorted peanut kernels is nearly 100%, with significantly improved visual quality. This lays a solid foundation for subsequent deep processing and gives us greater confidence in the safety of our final products."
Xingtai Zhongde Intelligent Technology Co., Ltd. is consistently committed to becoming a leader in the field of intelligent sorting. The company boasts a strong R&D team and a comprehensive after-sales service system. Its "Zhongde" brand color sorters are widely used across various industries including grains, nuts, medicinal herbs, plastics, and minerals, offering mature solutions for hundreds of materials such as rice, beans, goji berries, plastic flakes, and quartz sand. Moving forward, the company will continue to be driven by innovation, gaining deep insights into the segmented demands of various industries, and providing clients with more intelligent and customized sorting equipment, thereby promoting modernization and quality leaps in more traditional sectors.
