FAR INFRARED RAY GRAIN DRYING DEVICE

PROBLEM TO BE SOLVED: To prevent a grain to be dried from being excessively dried or burned- out when a driving power source to one or both of a supplying system and a feeding system to a flow-down surface of the grain for making the grain to be dried flow down in a dispersed particle state or a thin layer state is interrupted. SOLUTION: In this far infrared ray grain drying device, a far infrared ray irradiates the grain so as to dry the grain to be dried while the grain to be dried flows down in the dispersed particle state or the thin layer state. A far infrared ray radiator 102 is provided on a part confronting the flow-down surface 101 of the grain. A far infrared ray irradiation part 104 with respect to the grain (a) to be dried naturally flowing down the flow-down surface 101 is formed. When the driving power source to one or both of the supplying system and the feeding system to the flow-down surface 101 of the grain (a) to be dried is interrupted, a lower part 108 of the flow-down surface 101 is released with a conveyor gutter 107 of a grain feeding conveyor 106. Thus, the grains to be dried gathered on the flow-down surface are rapidly delivered to the outside. COPYRIGHT: (C)2003,JPO
