摘要
目前,国内谷物烘干机大部分为大型机械设备,占地面积大、成本高、难以移动,市场上缺少满足于中小型农户实际需求的烘干机。因此设计了一种可组装、热风余热再利用、循环干燥的小型谷物烘干机。该机采用箱式干燥机的结构、逆流循环干燥方法以及间歇式谷物干燥的工作方式,使用220V及380V交流电。创新设计的斗、锥状减速挡板,将烘干仓中的谷物均匀分散开来,提高烘干机烘干效率。烘干机具有移动、运输、存放方便,节能环保,自动排粮等特点。
At present,most grain dryers in China are large equipment,which cover large area,cost much,are difficult to move.However,there is a lack of dryers meeting the actual demand of small-scale farmers.Luckily,a new dryer,which can be assembled freely,recycle waste heat,dry circularly,has been designed.This dryer adopts the box-type structure,the technique of circular counter-flow drying that the grain-flow is in the opposite direction of hot airflow,the working mode of intermittent drying,and the electric energy of 220 V and 380 V alternating current.The innovative design of the bucket and pyramid baffle,through which the grain-flow disperses,increase drying efficiency.The dryer is convenient for moving,transport and storage,does good to energy saving and environmental protection,discharge automatically,etc.
