摘要： PROBLEM TO BE SOLVED: To provide a means for rapid drying and reordering of tobacco in large quantities which are processed in a short amount of time and in very little floor space.
SOLUTION: The method for rapid drying, cooling and reordering of the tobacco comprises a process for placing the tobacco on a continuous conveyor belt in fixed thickness, a process for transporting the tobacco on the conveyor through a dryer using a fluidized bed of heated air, a process for transporting the tobacco on the conveyor through a cooler using a fluidized bed of peripheral air, a process for transferring the tobacco to a steam tunnel having a vibration conveyor and a process for reordering the tobacco in the steam tunnel. The process for transporting the tobacco through the dryer has a process for sending air heated to a first fixed temperature to a first heating zone, a process for circulating the air in the first heating zone, a process for sending air heated to a second fixed temperature from the first heating zone to a plurality of downstream heating zones, a process for circulating the air in a plurality of the downstream heating zones, a process for reducing the water content of the tobacco to about 5%, a process for raising the temperature of the tobacco from about 200°F (about 93.3°C) to about 280°F (about 137.8°C).

摘要： A method and apparatus is given for a low residence time redrying of strip tobacco. The apparatus thoroughly and evenly dries and cools the tobacco consistently through the entire tobacco bed as it passes through the dryer (38) and cooler (32). The apparatus utilizes a plurality of individually controlled fluidized bed heating zones (22-30) for drying the tobacco. An additional fluidized bed cooling zone (32) is provided to cool the tobacco prior to reordering. A continuous conveyer (14) extends through the heating zones and cooling zones. A steam tunnel (40) is utilized to raise the moisture content of the dried tobacco to preselected moisture levels. A vibrating conveyer (60) moves the tobacco through the steam tunnel.

摘要： A process and apparatus for producing a smoking tobacco having a low nitrate content includes at least one stage through which a tobacco having a relatively high nitrate content, for example burley tobacco, continuously passes for continuous nitrate removal by dissolution. In the nitrate removal stage, a solvent is added to, for example, the burley tobacco to form a slurry. The free solvent, including dissolved nitrates, is decanted from the slurry leaving saturated burley tobacco. The saturated burley tobacco is subjected to an expression pressure to remove a further amount of solvent and dissolved nitrates therefrom. After the burley tobacco leaves the nitrate removing stage, it is mixed with another tobacco, such as, for example, a flue-cured tobacco. The tobacco mixture is then expanded and dried to a moisture content suitable for use in a smoking article. In order to provide a continuous uniform quantity of the tobacco mixture to the expanding-drying step, the mixture is bulked upon leaving the mixing step.
