This course is part of Module II: Technology and Practice on Grain Postharvest Loss Reduction within the webinar series on postharvest loss reduction organized by the WFP Centre of Excellence for Rural Transformation (WFP China COE). The series was held from August 27th to September 26th, 2024, with support from the Academy of China’s National Food and Strategic Reserves Administration (NAFRA).

The overall objective of this webinar series is to share China’s extensive experience, technologies, and practices in reducing postharvest loss. Across two modules—Module I: Experience on Grain Postharvest Management and Module II: Technology and Practice on Grain Postharvest Loss Reduction—a total of 16 Chinese presenters introduced China’s approaches to postharvest management and demonstrated key technologies applied by aggregators at various stages of the postharvest process.

Within this framework, the present course provides an overview of the engineering and technical measures for reducing grain storage losses in depots. It outlines the primary causes of grain loss during storage, the characteristics of storage in depots, and the main factors contributing to losses. The course emphasizes improving storage efficiency through optimal granary design, the adoption of new thermal insulation materials, and the implementation of airtight measures. It also addresses the integration of green storage technologies, the upgrading of loading and unloading equipment, and the enhancement of intelligent management in grain depots.
