PROBLEM TO BE SOLVED: To provide a device for drying the rice washing wastewater and its method capable of improving the drying efficiency of the rice washing wastewater. SOLUTION: This device 10 for drying the rice washing wastewater comprises a drying drum 20 supported rotatably on a spindle and heated by the flame of a jet heater 42 at its peripheral wall part 20A. The peripheral wall part 20A of the drying drum 20 is dipped in the rice washing wastewater 16 stored in a water tank 14. A bottom part of the water tank 14 is provided with an air vibrator 70 for supplying the air into the rice washing wastewater 16 for bubbling the rice washing wastewater 16. As the bubble 76 of the rice washing wastewater 16 is attached to the peripheral wall part 20A of the drying drum 20 to be heated and dried, the attaching property of the rice washing wastewater 16 to the drying drum 20 is improved, and the drying efficiency can be improved.
