高性能谷物干燥机的总体设计
摘 要
我国是一个谷物生产大国，收获后的谷物是否干燥及时，直接关系到谷物的储藏及后续的加工过程，每年由于不能及时干燥造成的谷物损失有500万吨之多。我国自然干燥已有千年的历史，大都是利用太阳能的热量和自然风来干燥的，它受气候影响很大。收获季节阴雨天气较多，谷物常常得不到及时的干燥而产生霉烂、发芽、变质。所以，无论在国外，还是在国内，都在大力发展干燥机。
本文主要是对谷物干燥机进行总体设计，根据谷物谷物干燥的要求进行干燥机的总体结构设计的研究；进行干燥过程的工艺参数设定，研究影响设计参数的因素，理论上明确干燥机各设计参数的确定方法。

Overall Design of High Performance Grain Dryer
ABSTRACT
China is a cereal production power, harvest grain is dry and timely, directly related to the storage of grain and follow-up processing, each year due to the dry can not be caused by the loss of grain as much as 5 million tons. China has a natural dry history of thousands of years, mostly using solar energy and natural wind to dry, it is affected by the climate. Harvest season more rainy weather, the grain is often not timely dry and produce mildew, germination, deterioration. Therefore, both in foreign countries, or in the country, are vigorously developing the dryer.
In this paper, the main design of the grain dryer is carried out, and the overall structure design of the dryer is carried out according to the requirement of cereal grain drying. The process parameters of the drying process are set and the factors influencing the design parameters are studied. The design of the dryer Parameter determination method.
