The air-film reinforced concrete spherical silo (hereinafter referred to as the air-film spherical silo) is a new type of storage structure. In order to explore the effect of the air-film spherical silo, the paper takes the first air-film spherical silo in China as a research object, and takes the wheat grain pile as the research target. The grain temperature quality, quality index, toxin and other indicators were tested and analyzed. The results showed that, during the grain storage process, the wheat grain heap in the air film spherical silo had no pests, no mildew, and all quality indicators met the suitable storage standard. The grain situation was stable and the quality was good, the air-film spherical silo is a new type of warehouse suitable for grain quality and safe storage.
