The present invention relates to a drying apparatus using a reheating manner, capable of uniformly drying an object to be dried and shortening the drying time. The drying apparatus of the present invention comprises: a drying room in which a plurality of drying racks are disposed, wherein each of the drying racks includes trays, which are stacked above and below while spaced at intervals; a circulation duct having an air inlet and an air outlets so as to circulate the inner air of the drying room; a ventilation fan installed inside the circulation duct to move air in a direction from the air inlet to the air outlet; a freezing unit having at least one heat exchanger, which is installed at the circulation duct so as to heat air passing through the circulation duct after the moisture of the air is reduced; and a reheating unit installed between the drying racks to reheat the air, which is discharged from the air outlet and passes through the drying racks, to lower relative humidity of the air. |
