Core Insights - The large-scale mechanized harvesting of summer wheat across the country has been completed, and the grain purchasing process is actively underway [1] - The new shallow round grain storage facilities have been put into operation, significantly improving efficiency and ensuring better food safety [1] Group 1: Grain Storage Innovations - The newly constructed shallow round warehouses have a single capacity of 10,000 tons and can increase overall efficiency by 4 to 5 times compared to traditional flat warehouses [1] - The use of mechanized grain loading in these new facilities allows for a closed environment, reducing dust and improving the working conditions for staff [1] Group 2: Scientific Grain Preservation Techniques - Various advanced grain storage techniques have been developed, including temperature control through air conditioning, internal circulation, and nitrogen gas adjustment [2] - Northern grain storage facilities utilize internal circulation to maintain a "cold core" during winter, while southern facilities commonly use nitrogen gas to reduce oxygen levels and slow down grain respiration [2] Group 3: Emerging Technologies in Grain Storage - The industry is exploring the use of carbon dioxide gas adjustment for grain storage, which requires maintaining a concentration of over 35% for 15 days [3] - Although carbon dioxide gas adjustment has potential benefits, its application is currently limited due to the instability and cost fluctuations of carbon dioxide sources [3] - The trend towards green scientific grain storage is expected to grow, with advancements in technology potentially reducing carbon capture costs and enhancing food preservation [3]
