<p>Disclosed is an apparatus for implementing a method for manufacturing a tobacco sheet. The apparatus includes: a pre-dryer for regulating the moisture content in a base web for the tobacco sheet; a coating device for coating a liquid perfume on the base web having a regulated moisture content; and a post-dryer for drying the base web on which the liquid perfume has been coated to form a tobacco sheet and regulating the moisture content of the tobacco sheet to a final moisture content. The post-dryer includes first to third heaters arranged in sequence along the direction in which the base web is transported, wherein the temperature of the third heater is feedback-controlled to adjust the moisture content of the tobacco sheet to the final moisture content, the temperature of the second heater is feed-forward-controlled in accordance with the moisture content of the base web that has passed through the pre-dryer, and the temperature of the first heater is fixed-value controlled in accordance with the result of a measurement by a component analyser of the light absorbance of the base web that has passed through the coating device.</p> |
