ABSTRACT:
The arrangement determines the moisture content of tobacco, in either leaf- or comminuted form, tobacco substitutes, other smokers' products, filter materials, cigarette and cigar papers and wrappings, related and analogous fibrous and other materials, and the like. The material in question is supported by a supporting arrangement. First and second electrodes are connected to an A.C. voltage source to form a capacitor. The electrodes are so disposed that the electric field joining the electrodes travels through the material being supported. The moisture of the material is determined by determining the effect upon the capacitor of the moisture in the material being supported and penetrated by the electric field. An arrangement is provided for compressing the material in question while the material is actually being supported and penetrated by the electric field.
