Abstract
Uncured tobacco leaves are heated by microwaves or in an electric high-frequency field prior to subdivision into ribs and strips. The strips are separated from the ribs, preferably with a stream of conditioned air, and are thereupon heated again and condensed, and the condensed strips are dried and cooled in vacuo prior to packing. The separated ribs are heated and are thereupon introduced into containers. The containers are then admitted into a vacuum chamber for cooling and drying of the ribs therein prior to packing.
