本文针对露天储粮受外界环境影响大,极易结露的现象,采取上顶及四周用竹杆架空,底部粮堆预留“丰”字型通风道,两山墙安装轴流风机,根据外界温湿度变化情况,适时排出垛内积热,缩小内外温差,使其控制在露点温度范围内,实现了不揭篷布避免结露现象,且达到了延缓储粮品质陈化、降低工人劳动强度、节约费用开支、确保储粮安全的目的。 In this paper, open storage grain affected by the external environment, extremely easy to condensation phenomenon, take the top and surrounded by bamboo overhead, the bottom of the grain heap reserved “Feng” type air duct, two gables to install axial fan, according to the outside world Temperature and humidity changes, the timely discharge stack within the heat, reduce the temperature difference between inside and outside, so that it is controlled at the dew point temperature range, to achieve a non-disclosure tarpaulin to avoid condensation, and to delay the quality of stored grain aging and reduce labor intensity , Save costs and expenses, to ensure the safety of stored grain.
