Abstract

Se proporciona un metodo para expandir el tabaco, que emplea un gas de dioxido de carbono. La temperatura del tabaco y el contenido de VH se ajustan antes de poner el tabaco en contacto con gas de dioxido de carbono. Durante la impregnación se sigue una senda termodinamica que permite que una cantidad controlada de gas de dioxido de carbono se condense sobre el tabaco. Este dióxido de carbono se evapora durante la despresurización ayudadndo a enfriar la capa de tabaco uniformemente. Luego de la impregnación, el tabaco puede ser expandido inmediatamente o mantenido en o por debajo de su temperatura post-liberación en una atmosfera seca para su posterior expansión.A method of expanding the tobacco is provided, which employs a carbon dioxide gas. The temperature of the tobacco and the VH content are adjusted before the tobacco is brought into contact with carbon dioxide gas. During impregnation a thermodynamic path is followed that allows a controlled amount of carbon dioxide gas to condense on the tobacco. This carbon dioxide evaporates during depressurization helping to cool the tobacco layer evenly. After impregnation, the tobacco can be immediately expanded or kept at or below its post-release temperature in a dry atmosphere for further expansion.
