Zhongde Color Sorter Revolutionizes Traditional Chinese Medicine Sorting Process, Enabling Precise Quality Upgrade of Medicinal Materials

Press Release Date: April 29, 2026

With the rapid development of the traditional Chinese medicine (TCM) industry and increasingly stringent international market standards for medicinal material quality, the precise sorting of Chinese medicinal materials has become a crucial link in ensuring efficacy and safety. Xingtai Zhongde Intelligent Technology Co., Ltd., leveraging its accumulation in cutting-edge optical recognition technology and intelligent algorithms, recently successfully launched a new generation of high-precision color sorter series customized for Chinese medicinal materials. This provides efficient and clean sorting solutions for various commonly used herbs such as honeysuckle, goji berries, astragalus, and cassia seeds, propelling the industry towards a new stage of intelligent and standardized production.

Chinese medicinal materials come in a vast variety, with significant differences in shape, color, and texture. Furthermore, impurities such as materials of differing maturity, mold, insect damage, or non-medicinal parts can easily get mixed in during harvesting and drying processes. Traditional methods relying on manual visual sorting are not only inefficient and costly but also struggle to ensure consistency between batches due to their subjective nature. They can no longer meet the demands of modern pharmaceutical companies and export standards. Having deeply investigated industry pain points, Xingtai Zhongde Intelligent Technology Co., Ltd. integrates advanced multi-spectral imaging technology with artificial intelligence to develop an intelligent color sorting system capable of accurately identifying subtle color differences, shape, texture, and even internal quality characteristics of medicinal materials.

The newly launched Zhongde intelligent color sorter has been comprehensively optimized for the special attributes of Chinese medicinal materials. The equipment employs ultra-high-resolution CCD sensors and a light source system with specific wavelength bands, enabling it to clearly capture extremely subtle color abnormalities, mold spots, scorch marks, or dyeing adulteration on the surface of the materials. Simultaneously, combined with its self-developed image processing algorithms, the machine can effectively distinguish genuine medicinal materials from impurities like stems, leaves, and shells. It can even detect some internally deteriorated materials that show no external signs, achieving industry-leading sorting accuracy. Taking goji berry sorting as an example, the equipment can accurately remove oily berries (black berries), moldy berries, branches, leaves, and off-color particles, retaining the brightly colored, high-quality fruits, significantly enhancing product grade and commercial value.

Beyond exceptional sorting accuracy, the Zhongde color sorter's engineering design fully considers the cleanliness and compliance requirements of the pharmaceutical industry. The parts contacting the materials are made of stainless steel that meets food safety standards, and the structure is easy to disassemble and clean, effectively preventing cross-contamination. The fully enclosed design, coupled with a negative pressure dust removal system, minimizes dust dispersion during the sorting process, safeguarding the production environment and operator health. The intelligent touch-screen control interface makes parameter adjustment and mode switching clear and intuitive. Operators can get started after simple training. The equipment can also memorize and store sorting programs for different medicinal materials, enabling rapid product changeovers.

Production efficiency and cost control are also core concerns for enterprises. This series of color sorters offers high processing capacity, with a single machine capable of handling hundreds to over a thousand kilograms of material per hour (depending on the specific herb), equivalent to the workload of dozens of skilled workers. This significantly reduces labor costs and management pressure. Its stable and reliable operational performance and modular design also minimize maintenance downtime, providing solid support for customers to achieve continuous and large-scale production.

A representative from Xingtai Zhongde Intelligent Technology Co., Ltd. stated, "We firmly believe that technology is the key to enhancing the efficiency of traditional industries. Applying cutting-edge color sorting technology to the field of traditional Chinese medicine is not only a commercial expansion but also a technological contribution to the inheritance and development of TCM culture. We hope that the Zhongde color sorter can become a trusted partner for numerous Chinese herbal slice manufacturers, pharmaceutical companies, and planting cooperatives, working together to safeguard the purity of medicinal materials and promote the high-quality development of the TCM industry."
