ABSTRACT:
Tobacco is treated by introducing a tobacco flavorant vapor such as menthol vapor into a conduit [an] and pneumatically conveying the vapor through the conduit. [The air in the conduit being maintained at a temperature of from about 75.degree. to 150.degree. F and above the vaporizing temperature of the flavorant.] Tobacco is injected into the conduit at a point downstream from the vapor injection. The flavorant vapor is uniformly deposited on the tobacco as it is carried down the conduit. A predetermined level of flavorant is maintained in the conduit through which the tobacco and flavorant vapor are pneumatically conveyed. The air in the conduit is maintained at a temperature of from about 75.degree. to 150.degree. F, which temperature is sufficient to prevent condensation of the vaporized flavorant in the conduit prior to adsorption of the flavorant on the tobacco.
