The moisture reduction rate in the drying was 0.04% WB/sec. The water content in the sheet-like mixture before drying was 21.3% WB, and the water content in the sheet-like mixture after drying was 12.7% WB. The tobacco sheet obtained did not have a curling shape. The swelling property of the tobacco sheet was measured in the same manner as in Example 1. Table 1 shows the results.
