储粮机械通风技术是粮食低温储藏的重要手段,也是绿色储粮的重要方法。中央储备粮库都有较完善的通风系统,但由于通风设备和操作不当,通风效果不理想引起粮堆温度不均衡,致使能耗较大,也容易产生结露和局部高温区易孳生害虫,影响粮食的储藏安全。根据《储粮机械通风技术规程》, Grain storage mechanical ventilation technology is an important means of low-temperature storage of grain, but also an important method of grain storage. However, due to inadequate ventilation and improper ventilation, the temperature of the grain piles is not balanced, resulting in large energy consumption and easy occurrence of dew condensation and local high temperature easy-breeding of pests. Affect the safety of food storage. According to “grain storage machinery ventilation technical regulations”
