Particles of a continuous tobacco stream are intimately contacted with and thus conditioned by finely distributed solid or fluid additives in a rotary drum into which the additives are supplied by one or more spray nozzles. Tobacco particles are propelled into the drum by a rotary winnower or by an impeller nozzle which discharges a current of compressed air. The flight spans of tobacco particles can be varied by changing the speed of the winnower or by changing the pressure of air which issues from the impeller nozzle. The weight of tobacco which is being fed to the winnower or impeller nozzle per unit of time is measured, and the results of such measurements are used to regulate the flight spans of propelled tobacco particles and the quantity of additives which are admitted into the drum per unit of time. The impeller nozzle or the winnower insures at least nearly complete separation of particles of tobacco during travel across a contact zone into which the spray nozzles discharge one or more finely dispersed additives, such as water, casing, flavoring agents or flowable solid additives.
