在高温季节,利用粮堆自身“冷源”控制和平衡粮堆上层温度、结合夜间低温有利条件,进行均温通风,不仅有效解决“冷心、热皮”造成的发热点,而且利用了“冷心”的冷源使储粮处于低温或准低温安全状态。由于通风条件选择合理,通风过程控制精细,实现了粮堆表层既均温又保水的目的。最终巧用粮堆自身“冷源”解决了“热皮”问题。
In the hot season, the use of grain piles themselves “cold source ” to control and balance the upper temperature of the grain pile, combined with favorable conditions of low temperature at night, the average temperature ventilation, not only effectively solve the “cold heart, Hot skin ” caused by the hot spots, And the use of “cold heart ” cold source of stored grain at low or quasi-low-temperature safe state. Due to the reasonable choice of ventilation conditions and fine ventilation control, the surface of the grain piles is both warm and water-retaining. Eventually use the food pile itself “cold source ” to solve “hot skin ” problem.
