Core Viewpoint - The article highlights the construction of China's first batch of five 9,000-ton gas membrane grain silos, which represent the fourth generation of new grain storage technology, emphasizing their advanced features and benefits for grain preservation [1][2]. Group 1: New Grain Silos Features - The gas membrane silos are 33 meters tall and have a diameter of 24 meters, each capable of storing approximately 9,000 tons of grain [1]. - The silos feature a unique multi-layer structure that includes a waterproof PVDF membrane, an insulation layer made of polyurethane, and a supporting structure of reinforced concrete, enhancing their airtightness and thermal insulation [2][4]. - The gas membrane silos have an airtightness performance that exceeds national high standards by more than six times and thermal insulation performance that is over three times better than traditional silos [2]. Group 2: Importance of Airtightness and Insulation - Airtightness and thermal insulation are crucial for grain storage as grains respire, consuming oxygen and releasing carbon dioxide, which can lead to nutrient loss if not properly managed [2][3]. - In high-temperature and high-humidity conditions, improper storage can significantly degrade grain quality over time [3]. Group 3: Cost and Safety Considerations - The initial construction cost of gas membrane silos is comparable to traditional silos, but they offer faster construction times, saving on time costs [4]. - The silos have passed fire safety audits due to the incorporation of flame-retardant materials, ensuring safety during operation [4]. - The five gas membrane silos are expected to be completed by the end of the year, adding a total storage capacity of 45,000 tons to the grain reserve [4].
