CA 2420296

The invention relates to a process for the improvement of the filling capacity of tobacco such as shredded tobacco leaves or ribs by treatment of the tobacco material having up to approx. 30 wt.-% initial moisture with a treatment gas composed of nitrogen and/or argon at pressures of 50 to 1,000 bar under continuous or stepped compression, followed by a continuous or stepped decompression, the compression and decompression steps taking place in either one autoclave or in cascade-like sequence in several autoclaves, and by subsequent thermal aftertreatment of the discharged tobacco material, which is characterized in that the thermal aftertreatment is carried out with a flowing heat-transferring medium of a mixture of permanent gases and superheated water vapour, wherein the proportion of permanent gas is kept constant at a value in the range from 10 to 60 vol.-%.

L'invention concerne un procédé pour améliorer le pouvoir de remplissage du tabac, par exemple de feuilles ou de côtes de tabac coupées, par le traitement du tabac présentant une humidité initiale allant jusqu'à environ 30 % en poids, avec un gaz de traitement constitué d'azote et/ou d'argon, à des pressions comprises entre 50 et 1000 bars, par compression continue ou étagée suivie d'une décompresion continue ou étagée, les processus de compression et de décompression étant réalisés soit dans un autoclave soit dans plusieurs autoclaves montés en cascade. L'invention est caractérisée en ce que le traitement thermique ultérieur du tabac ainsi traité est réalisé au moyen d'un agent caloporteur circulant, constitué d'un mélange de gaz permanent et de vapeur d'eau surchauffée, la part de gaz permanent étant maintenue à une valeur constante entre 10 et 60 % du volume.
