PURPOSE: A dryer is provided to achieve an increased drying efficiency and prevent environmental contamination by preventing gas emission and the object material from being discharged to the outside during drying. CONSTITUTION: A dryer comprises: a mixer(10) for accommodating materials to be dried, and which has an inlet port(12) and an outlet port(14) formed on the circumference of a mixer body(16); an air duct(50) for interconnecting the inlet port and the outlet port of the mixer body, in such a manner that the air discharged from the outlet port is circulated and fed to the inlet port; a condenser(80) arranged at an intermediate portion of the air duct; and a heater(95) interconnected between the condenser and the mixer. The mixer is provided with the high temperature air from the heater, and the moisture contained in the material in the mixer is vaporized and supplied to the condenser. The moisture is condensed in the condenser, and the condensed water is discharged to the outside. Subsequently, the dried air is heated by the heater, and fed to the mixer.
