20090090374 | Method and Feeder for Increasing Efficiency of the Expanding and Drying Process of Organic Materials, Particularly in a Jet Drier - 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 uses a gaseous expanding and/or drying agent under an absolute working pressure in the range from 2.5 kPa to 10 MPa, such as overheated steam. During transporting the material from the feeding zone to the zone of contact with the expanding and/or drying agent, a feeder, preferably a rotary vane feeder ( | 04-09-2009 |
