中国谷物干燥加工中的能源消耗状况

在任何一个国家的经济发展中，能源都扮演着一个重要的角色。在中国，尽管目前消耗在农业生产上的能源占全国能源消耗总量的比例很低，但随着中国农业现代化的发展，尤其是粮食干燥机械化的普及，农业生产对能源的需求将逐渐增加。该文对中国粮食干燥机械化的发展及现状进行了简单分析总结，对中国目前在粮食干燥中的能源消耗状况以及存在的问题进行了深入分析。完成的两组干燥实验结果表明，目前我国粮食干燥的单位能耗远远高于发达国家。因此，建议应在粮食干燥中大量采用干燥新技术、节能技术以及使用再生能源，以有效提高我国粮食干燥过程中的能源使用效率。

Energy consumption for grain drying in China

Energy resources play a crucial role in economic development in any country. Although the energy consumption in agriculture accounts for a lower ratio to the total energy consumption in China, there is a tendency of growing rural energy demand because of agricultural mechanization, especially increasing use of grain dryers. Following a review of the past and present situation of artificial grain drying in China, the authors discussed the energy consumption situations and problems in grain drying in China. Experimental study was reported in this paper on energy consumption of two types of dryers widely used in China. Three suggestions related to increasing energy efficiency in grain drying, namely, adoption of new drying technologies, application of energy conservation technologies, and development and utilization of regenerative energy resources, were proposed in this paper.
