DEHYDRATOR OF POROUS PLATE AND DEHYDRATION METHOD OF POROUS PLATE

摘要

PROBLEM TO BE SOLVED: To provide a dehydrator which efficiently dehydrates a porous plate.SOLUTION: A dehydrator of a porous plate of this invention includes: an air spraying duct 4 which is disposed on a surface of the porous plate 1 and sprays air to the surface; a spray hose 5 which is connected to a ceiling of the air spraying duct 4; an air suction duct 6 which is disposed on a rear surface of the porous plate 1 and suctions air on the rear surface; a suction hose 7 which is connected to a bottom surface of the air suction duct 6; a dehumidifier 8 which dehumidifies the air suctioned through the suction hose 7; a heater 9 which heats the air dehumidified by the dehumidifier 8; and a circulation blower 10 which suctions the air in the air suction duct 6 through the suction hose 7 and sends the air, which is dehumidified by the dehumidifier 8 and is heated by the heater 9, to the air spraying duct 4 through the spray hose 5.
