  • Patent number: 4516331
    Abstract: The drying apparatus includes a drum rotatably arranged in an outer box with a certain distance spaced from the inner surface of the outer box and housing therein materials to be dried. An air supply device supplies heated air into the drum, and a moisture removing device cooles air discharged from the drum by means of air taken from outside of the outer box to remove moisture from air discharged. Air discharged from the drum is guided to the moisture removing device through a first path. A space defined by the inner surface of the outer box and the outer surface of the drum constitutes a second path through which air passed through the moisture removing device is guided to the air supply device.
