On May 20, 2025, the on-site observation meeting for the Key Science and Technology Project of Henan Province, "Technological Innovation and Integrated Application for Disaster Response in Wheat and Corn under Abnormal Weather by Integrating Multi-source Data", was successfully held in Luoyang. As a sub-task undertaking unit, Zhengzhou Wangu Machinery Co., Ltd. showcased its project achievement, the "Mobile Rapid Dehumidifier for Wheat Grains", at the meeting, winning unanimous praise from attending experts.
Led by Professor Yang Qinghua from Henan Agricultural University as the chief expert, the project is jointly undertaken by scientific research institutions and enterprises, including Henan Agricultural University, Henan Institute of Meteorological Sciences, Henan University of Science and Technology, Henan Academy of Agricultural Sciences, Zhengzhou Wangu Machinery Co., Ltd., and Zhengzhou Zheng's Chemical Products Co., Ltd. Focusing on meteorological disasters such as harvest-time rainstorms, late spring cold snaps, high-temperature droughts, and waterlogging with overcast skies during the growth of wheat and corn, the project aims to:
- Construct a monitoring and early warning system;
- Analyze disaster-causing mechanisms;
- Develop disaster prevention/mitigation technologies and products;
- Innovate emergency loss-reduction equipment.
It establishes a technical system integrating "information, technology, products, and equipment" and spanning "pre-production, in-production, and post-production" stages for "disaster prevention, resistance, mitigation, and relief," ensuring disaster resilience during calamities and yield improvement in normal years.
As the undertaking unit for the sub-task "R&D of Rapid Dehumidification Equipment for Wheat and Corn Grains", Zhengzhou Wangu Machinery Co., Ltd. developed rapid dehumidification and quality-preserving disaster relief equipment for wheat and corn grains under abnormal weather. The "Mobile Rapid Dehumidifier for Wheat Grains" displayed at the meeting represents the company’s latest technological achievement, featuring:
- A breakthrough in traditional grain drying processes and structural designs, enabling rapid dehumidification and quality preservation of grains during rainy harvest seasons to reduce mildew losses;
- A mobile design for quick on-site operations under adverse weather, suitable for rural households and planting cooperatives in Henan to handle rapid grain dehumidification during disasters.
At the meeting, the company’s representatives reported the equipment’s technical performance and operation costs to experts and leaders from the Henan Provincial Department of Science and Technology and the Henan Provincial Department of Agriculture. The achievements were highly affirmed, with suggestions for optimization. Leaders urged the company to refine the product for market launch, aiming to:
- Ensure full grain harvests during disasters;
- Fulfill the responsibility of "storing grain through technology" with new-type productive forces;
- Implement the principle that "the Chinese people must always hold their food security firmly in their own hands."
