Zhongde Color Sorter Revolutionizes Nut Sorting Process, Enhancing Quality Standards in Peanut Processing Industry
Date: April 06, 2026
Issued by: Xingtang Zhongde Intelligent Technology Co., Ltd.
With the increasing global demand for product quality and safety in the food processing industry, technological innovation in the nut sorting stage has become a key driver of sector development. Recently, Xingtang Zhongde Intelligent Technology Co., Ltd. successfully launched a new generation of Zhongde Intelligent Color Sorter, which has been installed and commissioned in several large domestic peanut processing enterprises. With its exceptional sorting accuracy and stability, it brings a novel quality control solution to the peanut processing industry.
Technological Innovation: Precise Identification, Efficient Sorting
During harvesting and initial processing, peanuts are prone to mixing with moldy kernels, sprouted kernels, broken kernels, as well as impurities like stones and soil clumps. Traditional manual sorting or simple mechanical screening is not only inefficient but also struggles to thoroughly remove subtle defects and off-color particles, directly impacting the quality and safety of the final product. The Zhongde Intelligent Color Sorter has undergone in-depth technical optimization tailored to the characteristics of peanut material.
The equipment is equipped with a self-developed multi-spectral recognition system and high-resolution CCD imaging module, capable of accurately capturing minute differences in color, shape, and spectral features on the surface and within peanut kernels. Even moldy particles with colors similar to peanuts, or defective items overlapping during high-speed conveyance, can be instantly analyzed and judged by the system's advanced algorithmic models. Coupled with a high-performance air valve ejection system, it achieves millisecond-level precise removal, effectively separating defective products and impurities.
Core Advantages: Stable, Reliable, Cost-Effective, and Efficient
In practical applications, the Zhongde Peanut Color Sorter demonstrates significant advantages:
- Ultra-High Accuracy and Low Carry-Over Rate: While ensuring a very high rejection rate for defective kernels, it significantly reduces the rate of good product being mistakenly removed (carry-over), directly saving valuable raw materials for enterprises and improving yield.
- Strong Adaptability and Stability: The equipment offers flexible parameter adjustment capabilities for different varieties and sizes of peanut raw materials. Its core components and optical systems are designed for industrial-grade use, ensuring stable operation in long-term, high-load continuous production environments with low failure rates and easy maintenance.
- Intelligence and User-Friendliness: Featuring a full Chinese touch-screen intelligent control interface, parameter settings are clear and operation is straightforward. It supports data storage and traceability functions, facilitating production management and quality analysis for enterprises.
- Hygienic and Eco-Friendly Design: The entire machine uses materials and construction compliant with food production requirements, is easy to clean, and eliminates contamination risks. The low-energy-consumption design also reduces long-term operating costs for businesses.
Industry Impact: Driving Industrial Upgrading
As an important industry for edible oil and economic crops in China, enhancing the added value of deep-processed peanut products is crucial. The introduction of the Zhongde Intelligent Color Sorter enables processing enterprises to establish standardized and automated sorting processes. This not only significantly improves the quality consistency of final products—such as roasted peanuts, peanut butter, and peanut oil raw materials—enhancing market competitiveness, but also builds a robust technical defense line at the source of food safety control, meeting increasingly stringent access standards in domestic and international markets.
The project manager at Xingtang Zhongde Intelligent Technology Co., Ltd. stated: "We are consistently committed to applying cutting-edge optical recognition and artificial intelligence technologies to practical sorting fields. The solution launched for peanut sorting is precisely the result of in-depth understanding of customer pain points and technological breakthroughs. We hope that the stable performance of Zhongde Color Sorters will help more nut processing enterprises achieve production modernization and quality excellence."
Currently, this series of color sorters is not limited to peanut sorting. Its technological platform can be extended to the precise sorting of various nuts such as almonds, pecans, and macadamia nuts, as well as multiple categories of materials like grains and tea leaves, demonstrating powerful platform-based technological capabilities.
Looking ahead, Xingtang Zhongde Intelligent Technology Co., Ltd. will continue to deepen its efforts in the intelligent sorting field, persistently increasing R&D investment. With smarter, more efficient, and more reliable color sorting solutions, it aims to serve a broader range of material processing industries globally, helping customers create greater value.
