高大平房仓储粮度夏,粮堆存在较大的冷心和明显的热皮。试验表明:利用粮库已有的风机风道等设施采用下行式循环通风均衡粮温,能显著降低粮堆外围温度,缩小粮堆内部温差,操作简单、方便,粮堆和空间未产生结露等不良现象。
Large warehouse storage grain degree of summer, there is a large grain cooler and obviously hot skin. The experiment shows that the use of downstream circulating ventilation to equalize the grain temperature by the existing fan duct of the grain depot can significantly reduce the temperature outside the grain piles and reduce the temperature difference within the grain piles. The operation is simple and convenient, and the dew condensation does not occur in the grain piles and space And other undesirable phenomena.
