Abstract

PURPOSE: To prevent drying irregularity from occurring even in grain with different, initial water content value by changing the flow direction of the grain when it flows down a drying passage to a direction that orthogonally crosses the flow direction when the grain drops into a crossing flow-down delivery room. CONSTITUTION: When a specific amount of grain is filled into a drying machine body 101, dry hot air is generated in a hot air blowing room 102, and the inside of a dust-discharge wind room 103 is set to negative pressure state, hot wind passes through a main ventilation path 105, a plurality of hot wind rooms 107, a dry passage, and a wind discharge room and is delivered out of a machine. On the other hand, grain passing through the hot air rooms 107 and the dry passage flows down and is deposited in a crossing flow-down delivery room 114 while the flow is being changed toward left and right directions by a crest- type screening wall 113 and is successively delivered into a take-out room 121. In this manner, even grain with a different initial water content value can be uniformly dried without causing drying irregularity by a plurality of circulation flows for changing a flow direction and is allowed to flow down equally without causing flow-down irregularity.
