鉴于我国幅员辽阔,自然条件的区别较大,因此,各地在低温仓的建设中,应充分利用自然条件,结合地区特点选择低温储粮技术方案,建立有自身特色的低温储粮技术体系。本文就综合目前常用的低温技术手段,在比较各自工作原理的基础上,分析它们的优缺点和对低温储粮的适用情况,从中对比各种方案的经济性,以期为低温储粮技术方案的选择提供参考。 In view of the vast territory of our country and great differences between natural conditions, all localities should make full use of natural conditions in their construction of low-temperature silos and select low-temperature grain storage technologies based on their characteristics to establish their own technical system of low-temperature grain storage. Based on the comparison of their working principles, this paper analyzes their advantages and disadvantages and their application to low-temperature grain storage, and compares the economic benefits of various schemes with a view to the low temperature grain storage technology program Choose to provide a reference.
