本文分析了粮食烘干机发展现状以及不足，对其结构进行改进优化，设计出一种干燥周期更短、更加经济节能的粮食烘干机。一方面，提升输料管道的外侧设有保温套，减少热量损失。另一方面，在进风口处设置温度传感器，在储粮空间上部设置湿度传感器，缩短粮食的干燥周期。从而使粮食烘干机的性能达到更优。
This paper analyzes the development status and deficiencies of grain dryer. The structure of grain dryer is improved and optimized. A grain dryer with shorter drying cycle and more economical energy saving was designed. On the one hand, the outer sleeve of the hoist feeding pipe is provided with a thermal insulation sleeve to reduce heat loss. On the other hand, temperature sensor is set at the air inlet and humidity sensor is set at the upper part of grain storage space to shorten the drying period of grain.
