ABSTRACT:
A method and preferred apparatus for conditioning materials such as tobacco using an airflow distributor means. A conveyor transports the material along a path, and means to control the conditioning of the material are located at selected locations. A source of gas produces a gas stream, and means are operatively associated with the source of gas to selectively condition the gas stream. Flow straightening means having a structure such as a honeycomb panel are positioned upstream of the material being transported on the conveyor. The gas stream source is positioned to direct the gas stream through the flow straightening means to spread the gas stream evenly across the conveyor surface for uniform conditioning of the transported material. The conditioning may include heating and/or cooling the material, introducing moisture into the gas stream, adding chemicals into the gas stream, or selected combinations of these.
