1998年,国家投资3800万元在我库兴建了一批大型浅圆仓,该仓的优点是单仓储量大,机械化程度高。这在一定程度上缓解了我库仓容的紧张局面。但浅圆仓也有一定的缺点,如因粮层高、单仓储量大,装粮时容易产生自动分级现象。本项研究就是针对北方地区的气候特点和我库的实际情况,充分利用自然条件,按照机械通风技术的要求,选择在冬季对浅圆仓进行通风降温,以达到科学保粮效果。 1 材料和方法
In 1998, the state invested 38 million yuan in our library to build a number of large shallow silos, the warehouse has the advantage of a single large storage, high degree of mechanization. This to some extent eased the tension of our warehouse capacity. However, shallow warehouse also has some shortcomings, such as the storey due to high, single storage, easy to produce when grading automatic grading phenomenon. This study is aimed at the climate characteristics of the northern region and the actual situation of our library, make full use of natural conditions, in accordance with the requirements of mechanical ventilation technology, choose to ventilate and cool the shallow silos in winter to achieve the effect of scientific grain-conserving. 1 Materials and methods
