Abstract (en)

[origin: EP2042045A1] The invention relates to a method and a feeder for increasing the efficiency of the expanding and drying process of organic plant materials, particularly in a jet dryer used for comminuted organic plant materials, particularly tobacco materials. The dryer works with the use of a gaseous expanding and/or drying agent under an absolute working pressure in the range from 2.5 kPa to 10 MPa. Preferably, overheated steam is used as the gaseous working, expanding and/or drying agent, and during transporting the material (1) from the feeding zone (6) to the zone (9) of the contact with the expanding and/or drying agent, a feeder, preferably a rotary vane feeder (4) is flushed, preferably in a continuous manner, with a gaseous medium (11, 12) which is capable of absorbing moisture, under an absolute pressure from 2.5 kPa to 10 MPa, the temperature of the gaseous medium (11, 12), preferably air, is from 50 to 200°C, and residues of the process gas are removed from the rotary vane feeder (4). Openings (5, 7) are formed in the housing of the feeder according to the invention, delivering the gaseous medium to the moving spaces between the vanes (3), as well as openings (5A, 7A) leading out the gaseous medium from the moving spaces between the vanes (3), the openings (5, 7, 5A, 7A) being arranged respectively in the walls of the housing of the feeder (4).
