<p>PURPOSE:To shorten a drying time even when the temp. of blowing air is low by heating air after drying the same to blow drying hot air. CONSTITUTION:A reaction container 1 packed with a desiccant 2 and a storage container 6 packed with a water absorbing substance are connected by connection pipes 10, 11. Opening and closing valves 13, 14 are provided to both of the connection pipes 10, 11 and an air fan 12 is provided to at least one of them at one place and, when the valves 13, 14 are opened, the recirculation of air between the containers 1, 6 is made possible. Further, air passages 15, 16 communicating with a suction port 23 and a blow-out port 24 are provided to both ends of the container 1 through opening and closing valves 17, 18 and a heater 25 is arranged to the air passage 15. An air passage 19 is provided to the container 6 in contact with a part or whole thereof and one outlet of the passage 19 communicates with the suction port 23 and the other outlet thereof communicates with the blow-out port 24. Further, air passage change- over valves 20, 22 are provided and, when air flows to the blow-out port 21 from the suction port 23 through the container 1, drying hot air is blown out and, when air passes through the container 6, low temp. air is blown out.</p> |
