中文摘要：

玉米干燥是一项高能耗技术,常用的玉米干燥方法能源消耗高、品质损失大,合理利用自然冷资源开发一种低能耗、优品质的干燥技术一直是研究的热点。东北冬季外部空气湿度低、温度低,空气与玉米内部形成的湿度差、温度差大,从玉米干燥理论入手,分析了高温度差及高湿度差对玉米干燥速率的提高,使玉米干燥达到了低能耗、高品质的水平,进而得出了自然冷资源在玉米干燥节能技术中的优势,提出了玉米干燥的节能发展趋势。

英文摘要：

Corn drying is a technology of high-power consumption. The regular technology of corn drying has a huge loss of both energy and quality. Developing a low-power and high-quality corn drying technology in the use of natural cold resource is always a research focus. Go to have an overview on extant researches about the current situation of corn drying. To start with the theory of corn drying, study the impact of temperature difference and humidity difference on the rate of corn drying. Propose an energy-saving trend of corn drying after discusing the advantages of natural cold resource in the energy conservation techniques of corn drying in account of the phenomenon and problem of corn drying.
