<p>PURPOSE:To improve the dehumidifying efficiency of a titled dehumidifier, and to reduce the capacity of a regenerating heater, by flowing a circulating gas in a state of communicating with two preheating zones provided to the front and rear sides of a drying zone. CONSTITUTION:A drum-shaped rotor 1 is housed in a casing partitioned into four chambers by partitions 5 to obtain dried air A' by passing air A to be treated through a drying zone 3a, and to regenerate a regenerating zone 3b by regenerating air B obtained by heating the outside air C by means of a heater 4. A circulating path for communicating with the two pretreating zones 3c and 3d is formed to cool packed materials 2 by passing air E discharged from a blower 6 through the zone 3c of high temperature immediately after the regeneration for the purpose of recovering the moisture absorbing capability of the material 2. Here the air E' elevated to high temperature is passed through the zone 3d having saturated moisture absorbing capability to preheat the packed materials 2 so as to regenerate it to a certain extent. Then air E'' cooled to low temperature is circulated again by the blower 6 to the zone 3c to repeat the cooling and preheating in sequence.</p> |
