Abstract
A method of and an apparatus for accurately measuring the moisture content of a moving bed of a product, such as strip tobacco, are disclosed. As the bed of tobacco is conveyed by a perforated or porous conveyor, a flow of air is directed upwardly through the conveyor and into the bed of tobacco. The air flow agitates and homogenizes the tobacco to provide a localized area of the bed of tobacco that has a substantially uniform moisture content from top to bottom. A moisture sensor located downstream of the air flow measures the moisture content of the agitated portion of the tobacco bed.
