Abstract

Increases in filling capacity of 30 to 100% are achieved when tobacco material with a moisture content of 18 to 80% by weight and a temperature of -80.degree. to 100.degree. C. is accelerated to a velocity of at least 20 meters per second by means of a gaseous medium, is subsequently decelerated and is dried in a conventional way. The tobacco material can be accelerated, together with the gaseous medium, in a nozzle of the Venturi type or can be introduced into the fast-flowing gaseous medium.
