Abstract

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.
