An apparatus for producing a flavor for a swelling tobacco material which comprises: an extraction container (2) wherein a starting tobacco material (A) is brought into contact with supercritical carbon dioxide so that tobacco components are dissolved in the carbon dioxide; a separation container (14) which is connected to the extraction container (2) and by which a fat-soluble fraction of the tobacco components is separated from the tobacco components dissolved in the carbon dioxide and recovered; a circulatory pathway wherein the critical carbon dioxide is circulated between the extraction container (2) and an absorption container (38) filled with purified water while purifying by a purification layer (4) comprising activated carbon to thereby allow the purified water to absorb a water-soluble fraction of the tobacco components; and a recovery container (52) by which the purified water having absorbed the water-soluble fraction of the tobacco components is collected as absorption water from the absorption container (38).The fat-soluble fraction of the tobacco components and the absorption water are employed as flavors in synthesizing the first and second flavor elements.

L'invention concerne un appareil d'élaboration d'un arôme pour du tabac gonflé, ledit appareil comprenant : un contenant d'extraction (2) dans lequel du tabac inital (A) est mis au contact de dioxyde de carbone supercritique de manière à y dissoudre les composants du tabac ; un contenant de séparation (14) relié au contenant d'extraction (2) et servant à séparer et à récupérer des composants du tabac dissous dans le dioxyde de carbone une partie liposoluble des composants du tabac ; un passage de circulation permettant de faire circuler le dioxyde de carbone supercritique entre le contenant d'extraction (2) et un contenant d'absorption (38) rempli d'eau purifiée par une couche de purification (4) comportant du charbon actif de manière à ce que l'eau purifiée absorbe une partie hydrosoluble des composants du tabac ; et un contenant de récupération (52) permettant de recueillir l'eau purifiée qui a absorbé la partie hydrosoluble des composants du tabac sous la forme d'eau d'absorption provenant du contenant d'absorption (38). La partie liposoluble des composants du tabac et l'eau d'absorption sont utilisées comme arômes dans la synthèse de premier et deuxième éléments aromatiques.
