Abstract
Steam or high-temperature gas containing steam flows through a gas-flow drying pipe. Tobacco is fed from a feed port into the high-temperature gas flowing through the gas-flow drying pipe, and heated and expanded while it flows together with the gas. Steam or water is injected into the high-temperature gas flow from injection nozzles at the positions downstream from the feed port to change the gas temperature. Thereby, the heat quantity given to the tobacco from the high-temperature gas is controlled to prevent the tobacco quality from degrading.
