Title: Drying device

Abstract: A drying device in which temperature and humidity of a gas flow fed intoeach of plural helical dryers in the form of a cylinder (i.e., temperatureand humidity of an exhausted gas flow) can be each controlled independentof the other dryers. The drying device, is equipped with a casing. Thecasing includes therein at least a helical dryer 6 in the form of acylinder for exhausting a drying gas flow fed therein out of gasdistributed on its outer periphery to feed on a drying object, and anaxial-flow blower 5 connected to an entrance side of the helical dryer forinspiring a gas flow exhausted out of the helical dryer into the casinginside the same casing and feeding into the helical dryer again tocirculate said gas flow, in which a part of a gas flow inspired by theaxial-flow blower serves as a gas flow having a depressed dew point whichresults from splitting a gas flow exhausted out of the helical dryer anddepressing the dew point of the split gas flow in a dehumidifying facility1 located outside the casing.
