低温储粮综合技术是将太阳热反射涂料的应用技术 ,仓内环流调节粮堆温度技术及提高仓房气密性技术集为一体的综合储粮技术。在高大平房仓气密性达到一定要求后 ,用太阳热反射涂料对仓顶进行表面处理 ,当夏季气温最高时试验仓顶表面温度比对照仓低2 5℃ ,大大减少了仓外太阳辐射热对仓房的热能传递 ,改善了仓内的储粮环境 ,基本实现了准低温储粮。利用环流熏蒸装置对高大平房仓内的储粮分阶段进行环流 ,3天内 ,定时环流 36小时 ,试验仓仓温下降了 4 5℃ ,上层粮温平均下降了 0 9℃ ,仓底部的粮食水分基本无变化。此项试验证明 ,环流是平衡粮堆内部的温度即利用粮堆内部的自然冷源降低高温区粮温的有效技术途径。
Integrated low-temperature grain storage technology is the application of solar heat reflective coating technology, warehouse circulation circulation temperature regulation technology and improve the warehouse gas tightness technology as one set of integrated grain storage technology. After the air tightness of the tall bungalow reaches certain requirements, the top of the bunker is treated with solar heat reflective coating. When the summer temperature is the highest, the top surface temperature of the pilot bunker is 25 ℃ lower than that of the control bunker, which greatly reduces the solar radiant heat The thermal energy transfer to the warehouse improved the grain storage environment in the warehouse and basically realized the quasi-low temperature grain storage. Circulation fumigating device circulation of grain stored in tall warehouse in phases, three days, the timing of 36 hours of circulation, the warehouse temperature dropped 45 ℃, the average grain temperature decreased by 0 9 ℃, the bottom of the grain moisture Basically no change. This experiment proves that circulation is an effective technical way to balance the temperature inside the grain piles, that is, to reduce the grain temperature in the high temperature region by using the natural cold source inside the grain piles.
