Abstract:
A flash dryer of cut tobacco comprises a drying duct (16) for connecting a feeding section (14) of cut tobacco to a tangential separator (18). The drying duct (16) has an upstream-side duct portion (16a) extending straight from the feeding section (14) at an elevation angle ranging from 30° to 60° and a downstream-side duct portion (16b) curving upward in a convex shape. A dry gas that flows through the drying duct (16) may contain superheated steam.
