Group 1: Grain Storage Innovations - The traditional method of storing harvested corn, known as "ground grain," has been replaced by modern "grain apartments" in Qitaihe, Heilongjiang, enhancing storage quality and reducing spoilage [1][6] - The new storage facilities, or "grain apartments," are designed with durable materials and efficient ventilation systems, allowing for rapid moisture reduction in corn from 17%-18% to below standard levels within 5-7 days [8][10] - Qitaihe has constructed 18 drying warehouses this year, with a total storage capacity of nearly 4,000 tons, aimed at safeguarding food security and reducing losses [10] Group 2: Alternative Storage Solutions - In Henan, farmers have adopted "sunshine rooms," which are ventilated storage cages that elevate corn off the ground, preventing moisture damage and improving storage efficiency [11][14] - These "sunshine rooms" can hold over three times the amount of corn compared to traditional methods, significantly enhancing space utilization [18] - The reduction of grain loss by even 1% can equate to billions of pounds of grain saved, highlighting the importance of these innovative storage solutions in the grain supply chain [20] Group 3: Drying Technologies - In Shaanxi, drying towers have become essential for managing wet corn, with temperatures reaching 120℃-140℃ to quickly reduce moisture content from over 35% to below 23% [21][23] - The drying process includes a two-step method, where corn is first rapidly dried and then subjected to a slower, lower-temperature drying to meet national standards [23][25] - The drying facilities operate continuously, capable of processing 400 tons of corn daily, ensuring that small farmers can also access timely drying services [25][26]
