PROCESS FOR IMPROVING THE FILLABILITY OF TOBACCO Abstract of the Disclosure 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 nitro- gen 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 decompres- sion 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°C. This is achieved by precooling the treatment gas prior to supplying it to the autoclave or cool- ing 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.
