Abstract

A process reorders tobacco that has been expanded by impregnating the tobacco under pressure with liquid carbon dioxide, forming a solid mass of the tobacco and solid carbon dioxide, and heating the solid mass in an expansion zone to sublimate the carbon dioxide and thereby expand the tobacco. The expanded tobacco is discharged from the expansion zone and before the temperature of the expanded tobacco is below about 27°C, the tobacco is contacted with humidifying air having a temperature of about 27°C to about 33°C and a relative humidity of about 58% to about 88%.
