PROBLEM TO BE SOLVED: To provide a drying apparatus capable of improving heat efficiency and reducing its operating cost.SOLUTION: The drying apparatus includes: a closed drying line D connected with a drying blower 2, an adsorbing instrument 3, a drying heater 4 and a drying hopper 1; and a regenerating line R connected with a regenerating blower 17, a regenerating heater 18 and the adsorbing instrument 3. The adsorbing instrument 3 successively circulates an adsorbing region 22 for adsorbing a wet component in a drying gas, and a regenerating region 23 for removing the wet component adsorbed in the adsorbing region 22. The drying apparatus includes: a regenerating gas introducing line 19 in which the regenerating line R is connected with the regenerating blower 17 and the regenerating heater 18, and which is connected with the adsorbing instrument 3; an atmospheric opening line 21 in which one end is connected with the adsorbing instrument 3 and the other end is atmospherically opened; and a reflux line 20 branched from the atmospheric opening line 21 and connected with the regenerating blower 17 of the regenerating gas introducing line 19 and the upstream side of the regenerating heater 18. |
