粮食住上了“好房子”

Core Viewpoint - The introduction of the new grain storage technology, the gas membrane warehouse, represents a significant advancement in grain storage solutions, emphasizing energy efficiency and sustainability in response to evolving storage needs [1][2]. Group 1: New Grain Storage Technology - The gas membrane warehouse is recognized as the fourth generation of grain storage facilities and has been awarded for its innovative contributions to carbon neutrality [1]. - This new storage type integrates advanced technologies such as storage information control systems, intelligent ventilation, and grain condition monitoring, making it a representative of green storage solutions [2]. Group 2: Advantages of Gas Membrane Warehouse - Compared to traditional shallow round warehouses, the gas membrane warehouse shows less temperature fluctuation due to external conditions, and it has demonstrated better gas concentration maintenance during nitrogen and carbon dioxide tests [2]. - Energy consumption for cooling, air conditioning, and winter ventilation in the gas membrane warehouse is approximately 10% lower than that of average traditional warehouses [2]. Group 3: Structural Features - The gas membrane warehouse features a unique three-layer structure: an outer layer made of high molecular membrane material for weather resistance, a middle layer of high-density polyurethane for insulation, and an inner layer of reinforced concrete for structural integrity [2]. Group 4: Strategic Importance and Future Plans - The development of the gas membrane warehouse addresses the growing demands for improved thermal insulation, airtightness, and energy efficiency in grain storage, which traditional warehouses can no longer meet [5]. - The gas membrane warehouse is currently operational in Chengdu and nearing completion in Changsha, with plans for further construction in Jilin, Anhui, and Jiangsu due to its significant green energy advantages [5]. - Nationally, the capacity of standard grain storage facilities exceeds 730 million tons, with high-standard warehouses increasing annually, and low-temperature storage capacity reaching 220 million tons [5].
