目前,我国多数省份已开展了机械通风储粮,普遍认为它是一种“安全、经济、有效、简便”的储粮方法。但是机械通风作为一种科学的保粮方法,并不是随意应用的,除保证风网设计合理外,还必须掌握一定的操作管理技能,否则就达不到理想的效果。由于机械通风选择利用的是外界空气,因此大气的性质对通风效果有着决定性的影响,必须做到适时通风。我认为:要取得理想的通风效果,合理设计风网是前提,适时通风是手段,管理得当是保证。以往有关“网设计”、“通风时机”论述的较多,而对“通
At present, most provinces in our country have carried out mechanical ventilation and grain storage, which is generally considered as a “safe, economical, effective and simple” grain storage method. However, mechanical ventilation as a scientific method of grain-preserving is not free to apply. In addition to ensuring a reasonable design of the wind net, certain operational management skills must be mastered, otherwise, the desired effect will not be achieved. Due to the selection of mechanical ventilation is the use of outside air, so the nature of the air has a decisive effect on ventilation, ventilation must be timely. I think: To achieve the desired effect of ventilation, the rational design of the wind network is the premise, timely ventilation is the means to properly manage is a guarantee. In the past on the “network design”, “ventilation timing” more discussion, and "pass
