Prof. Zhang Yuanhui, Director of the U.S. BESS Laboratory, Visits Big Herdsman to Explore New Heights in Livestock Ventilation Technology

On May 9, Prof. Zhang Yuanhui, Director of the U.S. BESS Laboratory, Chair Professor at the University of Illinois Urbana-Champaign (UIUC), and member of the State Council Overseas Expert Advisory Committee, visited Big Herdsman Machinery Co., Ltd. in Qingdao for a research and inspection visit.Vice President Dr. Li Xiusong and Fan R&D Director Mr. Wang Yinhus, along with the core technical team of Big Herdsman, warmly received the delegation. Both sides held in-depth discussions on livestock ventilation technology R&D, laboratory construction, and industry development trends.

张元辉教授是畜舍通风与环境控制领域全球公认的权威专家。他长期从事通风系统理论研究和技术创新。他领导的畜舍通风与环境控制实验室是世界最权威的风机测试机构之一，是全球风机性能验证和标准制定的标杆。.

In recent years, Prof. Zhang has observed a significant increase in testing demand from Chinese fan manufacturers at the BESS Laboratory, reflecting the rapid rise of China’s livestock equipment industry on the global stage.As a leading fan manufacturer and large-scale livestock equipment provider in China, Big Herdsman—supported by the Ministry of Agriculture and Rural Affairs Key Laboratory and its strong technical expertise in ventilation—became a key focus of Prof. Zhang’s visit to China.

访问期间，张教授一行参观了…… 大牧人’该公司拥有国家级农业农村部重点实验室、先进风洞实验室和风机研发生产车间，深入了解了公司在风机性能优化、高风量低能耗设计以及智能环境控制方面的技术突破和应用成果。.

张元辉教授进入风洞实验室，与范氏研发总监王银虎先生现场进行了技术讨论。.

He observed the fan testing process in the wind tunnel laboratory, gaining a deep understanding of equipment configuration, testing standards, and data accuracy. He highly praised Big Herdsman’s independently built world-class wind tunnel testing platform.The company will establish long-term and in-depth cooperation with Prof. Zhang Yuanhui and the BESS Laboratory, benchmark against international top standards, and promote full alignment of China’s livestock ventilation technology with global systems, contributing Big Herdsman’s strength to the green and efficient development of the global livestock industry.

This visit by Prof. Zhang Yuanhui, Director of the BESS Laboratory, not only represents high recognition of Big Herdsman’s fan technology strength and R&D capability, but also marks a new chapter of deep cooperation with world-class scientific research resources.In the future, Big Herdsman will continue to uphold its mission of “making farming simple, reliable, environmentally friendly, and efficient,” driven by technological innovation and international cooperation. The company will continuously enhance its core competitiveness, lead China’s livestock equipment industry toward high-end, intelligent, and global development, and support the high-quality growth of the global livestock industry.
