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 and cooler. The apparatus utilizes a plurality of individually controlled fluidized bed heating zones for drying the tobacco. An additional fluidized bed cooling zone is provided to cool the tobacco prior to reordering. A continuous conveyor extends through the heating zones and cooling zones. A steam tunnel is utilized to raise the moisture content of the dried tobacco to preselected moisture levels. A vibrating conveyor moves the tobacco through the steam tunnel.
