PROBLEM TO BE SOLVED: To provide a drying device capable of reducing a size.SOLUTION: Moisture is removed from powders and granules by hot air supplied from a hot air supply line 6 into a drying hopper 3, and thereby, the powders and granules are dried. At this time, the air discharged from the inside of the drying hopper 3 to an exhaust line 12 flows through the exhaust line 12 toward a filter 13, and passes through the filter 13. A removing object contained in the air is removed by the filter 13. The powders and granules are supplied with the air into the drying hopper 3. At this time, the air discharged from the inside of the drying hopper 3 to the exhaust line 12 flows through the exhaust line 12 toward the filter 13, and passes through the filter 13. A removing object contained in the air is removed by the filter 13. Thus, one filter 13 is shared for removing the removing objects from air both at the time of drying the powders and granules and at the time of supplying the powders and granules to the drying hopper 3. |
