Flat-bottomed steel silos have become a core choice for grain storage, bulk material storage, and industrial warehousing worldwide, thanks to their large storage capacity, space-saving structure, and easy maintenance. However, their unique flat-bottom design and thin-walled metal structure make them highly susceptible to temperature and humidity fluctuations, which can lead to condensation, mold growth, localized overheating, and even material deterioration—directly threatening storage safety and quality. Mechanical ventilation is the most effective way to solve these problems, but unscientific operation can exacerbate risks such as silo wall condensation, material moisture regain, and dust explosions.
