Abstract
A method is for producing individual dosing quantities of a powdered product via a drum dosing device. Individual masses of multiple ejected dosing quantities are sequentially determined. A mass mean value is formed and compared to a predetermined inner target mass range. If the mass mean value is inside the range, the level of the partial vacuum acting on the dosing opening in the filling position remains unchanged, and the above formation of a mass mean value begins anew. If the mass mean value is outside the range, an adapted partial vacuum is ascertained such that in the case of excessively low mass mean value, the level of the partial vacuum is increased, and in the case of excessively high mass mean value, the level of the partial vacuum is decreased. The adapted partial vacuum is applied to the dosing opening in the filling position.
