Abstract
An apparatus for producing a flavor for expanded tobacco material has an extraction vessel (2) for bringing supercritical carbon dioxide into contact with tobacco material (A) to dissolve tobacco components in the carbon dioxide; a separation vessel (14) connected to the extraction vessel (2), for separating fat-soluble ingredients of the tobacco components from the tobacco components dissolved in the carbon dioxide to retrieve the fat-soluble ingredients; and a circulation path for circulating the supercritical carbon dioxide between the extraction vessel (2) and the absorption vessel (38) storing purified water while purifying the carbon dioxide by the purification layer (4) made of activated carbon, and absorbing water-soluble ingredients of the tobacco components in purified water; and a retrieval vessel (52) for retrieving the purified water, in which the water-soluble ingredients of the tobacco components are absorbed, from the absorption vessel (38) as absorption water. The fat-soluble ingredients of the tobacco components and the absorption water are used to produce first and second flavor elements as flavor.
