科学储粮对保证粮食安全,促进高效节能作业具有重大意义。通风储粮是很重要一个环节。根据天气状况和粮情,抓住有利时机,科学合理通风,采用分阶段通风作业法,尽可能通过自然通风、低功率风机通风和间歇通风,使粮堆温度随气温阶梯式下降,避免无效和有害通风,减轻结露,节约能耗,减少粮食水分的非良性散失,降低降温成本。另外,本文还从环流熏蒸、粮堆的隔热防潮和谷物冷却等方面阐述需着重注意的问题。 Scientific grain storage is of great significance to ensuring food security and promoting energy efficient operations. Ventilation grain storage is an important part. According to the weather conditions and grain conditions, seize the favorable opportunity, scientific and reasonable ventilation, the use of phased ventilation method, as far as possible through natural ventilation, low power fan ventilation and intermittent ventilation, the temperature of the grain piles down with the temperature to avoid ineffective and Harmful ventilation, reduce condensation, save energy, reduce the non-benign loss of grain moisture and reduce the cooling cost. In addition, this article also elaborates the issues to be paid attention to in the aspects of circulation fumigation, insulation and dampness of grain piles and grain cooling.
