Zhongde Intelligent Technology Launches New Tea Color Sorter, Enhancing Premium Tea Selection Accuracy
April 12, 2026 – Xingtai Zhongde Intelligent Technology Co., Ltd. officially announced the successful development and launch of a new generation of high-precision tea color sorting equipment. Deeply integrating artificial intelligence visual recognition with multispectral analysis technology, this machine is designed to address industry pain points in traditional tea sorting, such as the difficulty in accurately removing yellow leaves, old stems, discolored particles, and fine impurities. It provides core equipment support for the high-standard processing of premium teas like Longjing, Biluochun, and Maofeng.
In the field of premium tea processing, the purity and uniformity of raw materials directly determine the final product grade and market value. Traditional manual sorting suffers from low efficiency and poor consistency, while conventional color sorters often lack sufficient discrimination for subtle color variations and complex-shaped impurities. The tea-specific color sorter released by Zhongde Intelligent Technology has broken through these technical barriers. It is equipped with the company's self-developed "DeepVision 3.0" intelligent recognition system. Trained on massive datasets of tea leaf images, this system can not only quickly distinguish color differences between tea leaves and stems or yellow leaves but also accurately identify and sort out fine foreign-colored impurities such as small insects or plastic fibers through multi-dimensional features like shape and texture. Combined with high-resolution CCD sensors and multi-band light sources, the equipment clearly presents surface and internal quality information of the materials, ensuring thorough inspection.
Production efficiency and intelligent capabilities are other highlights of this upgrade. The model adopts a novel dual-track parallel sorting channel design, with a maximum single-machine processing capacity reaching 1,200 kilograms per hour, representing an approximate 25% increase over the previous generation. An innovative intelligent feeding system adaptively regulates material flow rate and speed, ensuring even distribution of tea leaves within the channels for optimal imaging conditions. The sorting actuator employs a micro-ejection valve array with a response time shortened to the millisecond level, enabling precise, targeted removal even at high operating speeds, effectively reducing the mis-sorting rate and loss of high-quality raw materials.
"We conducted in-depth research into the actual needs of major tea-producing regions," stated the R&D Director of Zhongde Intelligent Technology. "The new equipment not only enhances sorting accuracy but is also dedicated to providing integrated intelligent solutions for tea enterprises." The built-in cloud data management system can record and analyze sorting data for each batch of tea in real-time, including defect types, rejection rates, production statistics, and more, presenting them in visual charts. Managers can remotely monitor production status, adjust parameters, or perform fault diagnosis via mobile terminals, enabling digitalization and traceability in tea processing.
Furthermore, the design fully considers the special requirements of tea production. Core optical components are equipped with constant temperature, moisture-proof, and automatic cleaning functions, ensuring stable operation even in high-temperature, high-humidity workshop environments. The entire machine utilizes food-grade stainless steel and eco-friendly materials, complying with food safety production standards. Modular design simplifies maintenance and upkeep, significantly reducing long-term operating costs for users.
Currently, this new tea color sorter has completed trial operations at several large domestic tea groups and received positive feedback. Trial customers reported that the equipment significantly improved the yield ratio of premium and first-grade teas while reducing manual re-inspection requirements by approximately 30%, demonstrating clear comprehensive benefits. Xingtai Zhongde Intelligent Technology Co., Ltd. remains focused on the deep research, development, and industrial application of intelligent sorting technology. In the future, the company will continue to introduce innovative products for more sectors such as grains, nuts, minerals, and recycled resources, assisting global clients in achieving cost reduction, efficiency improvement, and quality enhancement with cutting-edge technology.
