Abstract

Process for improving the fillability of tobacco, such as cut tobacco leaves or ribs and tobacco additives by treating the tobacco in an autoclave with a containing nitrogen and/or argon at pressures up to 1000 bar, with subsequent decompression and a gas heat treatment. The tobacco or the treatment gas supplied to the reactor and/or the decompression step are carried out in such a way that the discharged tobacco which is thereafter supplied to a subsequent heat treatment has a temperature, at introduction to the heat treatment step, below 0 DEG C. This is achieved by precooling the treatment gas prior to supplying it to the autoclave or cooling the treatment gas while supplying it to the autoclave and/or additionally cooling the autoclave and/or precooling the tobacco and/or injecting subcooled or liquefied treatment gas into the autoclave. The process includes multistage treatment gas whereby supply and decompression steps are carried out in a cascade-like manner.
