收购的粮食如何保存？我们到河南、湖南等地的中储粮仓看看如何用"黑科技"守护粮食安全。 在河南新郑中储粮新港直属库，10个高度超过30米的"高个子"浅圆仓分列两排，一个浅圆仓就装有9800 吨小麦，但占地面积却是传统平房仓的1/4。虽然储粮量大，一人却可以"足不出户"管理3到4个浅圆 仓，通过自动化控制系统，可以线上实时查看粮食状态。 在浅圆仓配套的工作塔，粮食通过进粮口后，如同乘坐电梯，由提升机送到4楼圆筒筛进行初步清理， 再被分送到2、3楼振动筛进一步清理除杂。工作人员介绍，整个工作塔设计产能是200吨/小时，三到四 天就可以完1万吨的仓房入库。入库快，出库同样高效。利用粮食自流惯性，通过仓壁设置的出粮口， 每小时可出库200吨粮食。 气膜仓：粮仓有了"新外衣" 同样利用粮食自流惯性的粮仓，还有这个正在建设中的9000吨级气膜粮仓。在湖南长沙望城区，5个刚 刚充气成型的"白胖子"气膜仓挺立在绿树之间，它们设计装粮高度26.6米，内径24米。 小麦适宜在密闭、干燥、25摄氏度以下的环境中储存，否则易滋生霉菌、虫害。气膜仓最外面是气膜 层，里面有起支撑作用的钢筋混凝土层和起保温隔热作用的聚氨酯层，这三层一体化成 ...

Core Insights - The article highlights the advancements in grain storage technology in Henan province, emphasizing the importance of efficient grain collection and preservation methods to ensure food security in China [2][9][24]. Group 1: Grain Collection and Processing - Henan province accounts for one-fourth of the national summer grain production, consistently exceeding 750 billion jin (approximately 375 million tons) annually [2]. - Due to weather conditions, wheat procurement in Henan has started about 10 days earlier than usual, with 548.1 million tons of new wheat purchased as of June 24 [4]. - The use of a WeChat mini-program for grain sales has significantly reduced the time required for farmers to sell their grain [2]. Group 2: Storage Technology Innovations - Modern grain storage facilities in Henan, such as the new circular silos, can hold 9,800 tons of wheat while occupying only one-fourth the area of traditional flat warehouses [9]. - Automated control systems allow for real-time monitoring of grain conditions, enhancing management efficiency [9]. - The design capacity of the grain storage system is 200 tons per hour, allowing for rapid entry and exit of grain [11]. Group 3: Advanced Storage Solutions - The article discusses the construction of gas membrane grain warehouses in Hunan, which are designed to maintain optimal storage conditions and prevent spoilage due to high humidity [15][17]. - The gas membrane warehouses have a height of 26.6 meters and a diameter of 24 meters, providing a significant storage capacity while ensuring a controlled environment [15]. - The use of nitrogen gas technology in these warehouses enhances their airtightness, prolonging the freshness of stored grain [19]. Group 4: Historical Context of Grain Storage - The article contrasts modern storage methods with historical grain storage practices, such as the ancient Li Yang granaries, which were capable of storing over 30 million jin (approximately 15,000 tons) of grain [26]. - The evolution from traditional storage methods to modern automated systems reflects advancements in technology and the growing importance of food security [24][30]. Group 5: Comparative Analysis of Storage Structures - The article compares cylindrical silos and building-style warehouses, noting that cylindrical structures distribute internal pressure evenly, while building-style warehouses offer easier maintenance and lower construction costs [37]. - The choice of storage structure is influenced by factors such as safety, investment costs, and operational efficiency [39].
