Abstract

Se suministra un proceso para expandir tabaco que emplea gas de dióxido de carbono. La temperatura y el contenido OV del tabaco se ajustan antes de poner en contacto el tabaco con el gas de dióxido de carbono. Se sigue durante la impregnación una ruta termodinámica, lo que permite que se condense en el tabaco una cantidad controlada de gas de dióxido de carbono. Este dióxido de carbono líquido se evapora durante la despresurización ayudando a enfriar el lecho del tabaco uniformemente. Después de la impregnación, el tabaco puede ser expandido inmediatamente o guardado a, o bajo su temperatura de postdesfoque en una atmósfera seca para una subsecuente expansión.A tobacco expansion process is provided that uses carbon dioxide gas. The temperature and OV content of the tobacco are adjusted before the tobacco is brought into contact with the carbon dioxide gas. A thermodynamic path is followed during impregnation, allowing a controlled amount of carbon dioxide gas to condense in tobacco. This liquid carbon dioxide evaporates during depressurization helping to cool the tobacco bed evenly. After impregnation, tobacco can be expanded immediately or stored at or below its post-defocus temperature in a dry atmosphere for subsequent expansion.
