Global food security relies not only on stable grain yields during planting seasons, but also on scientific and standardized grain storage management throughout the whole year. Traditional grain storage methods, which depend on natural ventilation and manual inspection, are plagued by high spoilage rates, unstable grain quality and heavy labor reliance. With the rapid iteration of agricultural science and technology, modern intelligent and green grain storage solutions have become the core driving force to reduce post-harvest losses, preserve grain nutrition and promote sustainable development of the global grain industry.
