Abstract:
A dryer comprising:a far infrared radiator that emits far infrared radiation for drying a to-be-dried object; a drying chamber in which far infrared radiation emitted by the far infrared radiator is directed to the to-be-dried object to dry the to-be-dried object; a plenum chamber for preparing a downflow of hot air toward the drying chamber; a frame to which a plurality of the far infrared radiators are mounted and which is provided with an opening for jetting the hot air that flows down from the plenum chamber toward the drying chamber; an elevating device for varying a distance between the to-be-dried object and the far infrared radiators; a hot air closed circulation path for circulating the hot air that is heated up by heat generated from the far infrared radiators; and a control device for controlling a temperature in the drying chamber, an irradiation time of far infrared radiation, a surface temperature of the far infrared radiator and a distance between the far infrared radiator and the to-be-dried object.
