FAR INFRARED GRAIN DRIER

摘要

PROBLEM TO BE SOLVED: To prevent obstruction from being caused to operation due to the thermal expansion of a lower spiral and a grain collecting chamber wall surface due to radiant heat by a far infrared radiator tube in a far infrared grain drier. SOLUTION: In a far infrared grain drier provided with an operational control device supplying the hot air from a burner to a far infrared radiator tube and using the radiant heat generated from the surface of this radiator tube to dry, the burner is controlled to burn at a fuel flow rate on the minimum side in the range of the fuel flow rate capable of combustion regardless of the setting conditions before the operation of the operational control device in the operation performing the combustion of the burner without feeding grain.
