ABSTRACT:
An improved method and apparatus for treating particulate material with two or more liquid additives in a rotatable cylinder involves the use of a pressurized fluid such as steam directed obliquely against the inner wall of the cylinder to effect a cleaning action on the inner wall as the cylinder is rotated and to augment agitation action produced by the rotational movement of the cylinder and gravitational forces acting on the particulate material. Strategically located spray nozzles apply controlled amounts of the liquid additives to the particulate material as it is undergoing agitation by the combined effects of the applied forces. The method and apparatus disclosed are particularly suited to the treatment of tobacco with casing materials.
