结合浅圆仓储粮工作的实际情况,通过利用东北地区冬季自然寒冷气温机械通风降低粮温,夏季采取压盖保暖措施,致使粮堆的“冷心”不被破坏,而呈低温状态,从而达到了减缓陈化,安全储粮和保鲜的目的,获得了较好的经济效益和社会效益. Combining with the actual situation of shallow circular grain storage work, the grain temperature was reduced by using mechanical ventilation of natural winter temperatures in winter in Northeast China, and the gland was kept warm in summer. As a result, the “cold heart” of the grain piles was not damaged, So as to achieve the purpose of alleviating aging, storing grain safely and keeping fresh, and obtaining good economic and social benefits.
