ABSTRACT:
To determine the filling capacity of tobacco, a predetermined quantity of tobacco is filled into a volume of known cross-section forming part of a press, closed on one side by a movable plunger, and the length of the tobacco column and the force acting on the tobacco during compression of the tobacco by the plunger are measured as a function of time. The output data are processed by at least one computer while the tobacco is being packed into packaging containers by means of the press. The length of the tobacco column is determined from the measured distance covered by the movable plunger of the press which compresses the tobacco and in doing so moves it into the packaging container. The force acting on the tobacco is measured from the pressure required to drive the plunger, or from the supporting force required to hold the packaging container, or from the force occurring at the plunger or its drive elements. Additional parameters such as tobacco temeprature and moisture content governing the value of the filling capacity are determined in independent measurements and fed into the computer. The method is preferably applied to leaf tobacco.
