Core Viewpoint - The article highlights the launch of the National Grain and Material Reserve Science and Technology Activity Week, emphasizing the importance of technological innovation in ensuring national food security through advancements in grain circulation and storage technologies [1]. Group 1: Technological Innovations - Ten technological innovations in grain circulation have been released, focusing on areas such as grain storage and food processing [5]. - The smart green storage technology system utilizes artificial intelligence for high-precision monitoring and traceability of stored grain, enhancing management levels [5]. - An intelligent sampling system for grain acquisition has been implemented in Yiyang, Hunan, automating sampling and quality inspections for rice and corn [7]. Group 2: Grain Drying and Storage Improvements - In Sichuan, the process from harvesting wheat to drying and storage has been optimized to ensure that grain does not stay overnight, enhancing efficiency [8]. - The drying centers utilize advanced technology to ensure uniform heating of grain, maintaining moisture content between 12.5% and 13.5%, which meets national storage standards [16]. - By 2025, a shared drying model will be introduced in San Tai County, supported by government subsidies to reduce production costs and improve post-harvest grain handling [18]. Group 3: Impact on Grain Loss Reduction - The establishment of 44 drying centers in San Tai County aims to minimize post-harvest losses, with an expected reduction of over 30,000 tons of grain spoilage annually [18]. - Nationwide, over 5,500 post-harvest service centers have been built, promoting the use of 10 million sets of scientific grain storage tools to aid in reducing grain loss [19].
