ABSTRACT:
A method and an apparatus for the determination of the filling capacity of tobacco and the hardness of cigarettes includes a container containing tobacco compressed by a test plunger driven in a pre-set manner by a motor, such that the force exerted on the tobacco is measured and passed to a computer. The length of the tobacco column is also measured. After the compression movement of the test plunger and while it rests in its end position for a relaxation period, the force acting on the tobacco is measured at pre-set time intervals and signals indicative thereof are passed on to the computer. The temperature and the moisture of the tobacco are determined, enabling the measured values to be adjusted to reflect standard conditions. The apparatus for determining the hardness of cigarettes differs from the apparatus for the determination of the filling capacity of tobacco only in the construction of the test plunger and the sample holder.
