A drying machine comprising: a clothes holding unit to hold clothes therein; a drying passage including a heater to supply heated air to the clothes holding unit; a dehumidification passage to remove moisture from air exhausted from the clothes holding unit and to supply dehumidified air to the drying passage; a heat exchanger to condense moisture from air exhausted from the clothes holding unit; a moisture absorption unit including a desiccant to absorb moisture from the air exhausted from the clothes holding unit and a housing to hold the desiccant; a circulation fan provided in the drying passage or the dehumidification passage to circulate air, a renewable passage to supply air from outside the passage to the moisture absorption unit, to renew the desiccant, having absorbed moisture to saturation, by drying after passing the heat exchanger, the moisture absorption unit comprising a renewable portion provided in the renewable passage; and a moisture absorption portion provided in the dehumidification passage to absorb moisture of the air circulating in a moisture absorption passage, the drying machine further comprising a shaft on which the desiccant is rotated as its axis, and a motor to rotate the desiccant absorbing the moisture to change a location of the desiccant provided in the renewable portion and the moisture absorption portion, wherein the dehumidification passage comprises: a condensation passage comprising the heat exchanger to condense moisture from the air exhausted from the clothes holding unit; and the moisture absorption passage comprising the moisture absorption unit to absorb moisture from the air, characterized in that the moisture absorption passage is connected with the condensation passage in parallel, wherein the dehumidification passage further comprises a passage change damper to selectively direct the air from the clothes holding unit to one or both of the condensation passage and the moisture absorption passage, the passage change damper being operable in a plurality of modes including: a first mode to direct air to the condensation passage and inhibit air movement to the moisture absorption passage, a second mode to inhibit air movement to the condensation passage and direct air to the moisture absorption passage. a clothes holding unit to hold clothes therein;
