Zhongde Color Sorter Assists Peanut Industry Upgrade, Ensuring Food Quality and Safety through Efficient Sorting
Date: April 30, 2026
With consumers' increasing demands for food safety and quality, the food processing industry's need for precise sorting during production is growing. In this context, Xingtai Zhongde Intelligent Technology Co., Ltd. provides an efficient and intelligent solution for medium and large-scale peanut processing enterprises with its leading optical sorting technology. Recently, the company's new generation of Zhongde intelligent color sorters has been successfully deployed in large processing plants across major peanut-producing regions. Its exceptional sorting accuracy and stable performance have earned widespread praise from customers.
As a significant cash crop and food ingredient, peanuts often face challenges during processing, such as moldy kernels, discolored kernels, stones, glass fragments, and plastic film debris. Traditional manual sorting methods are not only inefficient and costly but also struggle to ensure consistency, posing food safety risks. The Zhongde intelligent color sorter utilizes high-definition CCD optical imaging systems and multi-spectral light source technology to accurately identify subtle differences in the color, shape, and texture of peanut kernels. Whether it's black spots caused by slight mold or kernels suspected of aflatoxin contamination due to improper storage, the machine can swiftly identify and precisely eject them using high-pressure air nozzles while operating at high speeds. This effectively reduces the potential content of hazardous substances like aflatoxin B1 in peanut products, safeguarding the safety of end products from the source.
In addition to strict control over safety-related defects, the equipment also focuses on enhancing the overall appearance and commercial value of the products. It can effectively separate unpeeled red skins, mixed varieties of discolored kernels, and impurities like sand and straw debris introduced during harvesting and drying. Its unique design combines multi-layer screening with optical sorting, initially grading peanuts by size through vibrating screens, followed by targeted color sorting for different grades. This significantly improves overall sorting efficiency and accuracy. Users can flexibly set sorting parameters based on market demands for different grades, easily achieving product classification to meet raw material standards for various scenarios, including high-end catering, export, and snack manufacturing.
The engineering team at Xingtai Zhongde Intelligent Technology Co., Ltd. understands that equipment stability is key to ensuring continuous large-scale production. The new generation of Zhongde color sorters has undergone comprehensive upgrades in core components. The independently developed intelligent image processing algorithm features robust self-learning and adaptive capabilities, enabling it to handle appearance variations in peanuts from different regions and varieties due to climatic and soil conditions. This ensures long-term stability in sorting standards. The sturdy industrial-grade body structure, efficient dust removal and cooling systems, and modular design allow the equipment to operate stably for extended periods, even in dusty processing environments, greatly reducing maintenance frequency and operational costs. Meanwhile, the equipped touch-screen human-machine interface is intuitive and easy to operate, with parameter settings and data statistics clearly displayed, facilitating quality traceability and process optimization for production managers.
Currently, this peanut color sorter has been deployed in several well-known nut processing enterprises across China. Customer feedback indicates that after introducing Zhongde equipment, the selection rate of peanut raw materials has increased by approximately 25%, manual re-inspection costs have decreased by over 60%, and customer complaint rates due to impurities and defective products have significantly dropped. This not only directly enhances the market competitiveness of enterprises but also provides solid technical equipment support for the Chinese peanut industry chain's development toward standardization, branding, and higher value addition.
Xingtai Zhongde Intelligent Technology Co., Ltd. remains committed to deeply integrating cutting-edge optical recognition, artificial intelligence, and industrial automation technologies to provide professional intelligent sorting solutions for global agricultural product and material processing sectors. In the future, the company will continue to focus on technological research and development, expanding the application of its equipment in more material sorting scenarios. It aims to help more industry customers achieve their core goals of improving quality, increasing efficiency, and reducing costs, thereby driving the intelligent upgrading of industries.
