结合盖膜技术,对单堆包装粮堆采用吸出式多管高压离心通风机进行负压通风。试验结果表明:该方法不仅可以快速降低和均衡粮温,增强粮食的储藏期间的稳定性,延缓粮食陈化,达到防虫防霉的效果;而且操作简便、方式灵活多样、成本低、收效快。
Combined with the cover membrane technology, the single pile of packaged food piles using suction-type multi-tube high pressure centrifugal fan for negative pressure ventilation. The test results show that the method not only can quickly reduce and balance the grain temperature, enhance the stability of the grain during storage, delay the grain aging, and achieve the effect of preventing mold and mildew; moreover, the method has the advantages of simple operation, flexible and diversified ways, low cost and quick effect.
