常规露天储粮是将油布直接盖在粮面上(简称塌顶堆,下同),直接受太阳辐射,风吹雨淋,储粮易生虫、发热、结露变质,这给保化人员带来繁重的体力劳动。为了解决这些问题,将露天堆塌顶储粮改为堆顶架空储粮,这既能使粮堆温度变化小,也能使储粮安全度夏,在机械通风作用下,便于熏蒸,杀虫效果好。且有近8个月的准低温(平均粮温15℃以下)储存期,起到了延缓粮食品质劣变,不易发热结露,也对露天堆规范化管理奠定了良好基础。
Conventional open-air grain storage is the tarpaulin directly covered in the grain surface (referred to as the collapse of the heap, the same below), the direct solar radiation, wind and rain, stored grain susceptible, fever, condensation degeneration, which give protection personnel Bring heavy manual labor. In order to solve these problems, the open top pile of stored grain to the top overhead storage grain, which not only make small changes in the temperature of the grain piles, but also to make the grain storage safety summer, under mechanical ventilation, easy fumigation, insecticide Good effect. And nearly 8 months of quasi-low-temperature (average grain temperature below 15 ℃) storage period, played a delay in the deterioration of food quality, easy to heat condensation, also laid the foundation for the open pit heap of standardized management.
