PROBLEM TO BE SOLVED: To prevent the mass of granulation objects to be dried with adherence from being formed and to reduce the space of a drying device, by drying the granulation objects to be dried by a microwave, and by accumulating the granulation objects to be dried for drying while the number of carrying granulation objects to be dried per unit area is increased. SOLUTION: A first dryer 1 has a microwave-generating device 2 on the ceiling surface of the inner wall of a box-shaped body. A carrier means 3 consisting of a belt conveyer is provided, granulation objects 4... to be dried are carried from the outside of one side surface to the outside of the other through the inside of the dryer 1 for drying. When hot-air drying is used together as the heating means of the dryer 1, drying efficiency is improved. The granulation objects 4 to be dried passing through the dryer 1 is densely accumulated in a tray 5 that has been thrown. Furthermore, the plurality of trays 5 are accumulated up and down for drying in a second dryer. In a drying method, a microwave, the combination of the microwave and hot air, the hot-air drying, or the like is properly selected.
