The influence of powder bed porosity variations on the filling of hard gelatin capsules by a dosator system

The weight variation of gelatin capsules filled by a dosator-type machine has several possible causes, one of which, the presence of density variations within the powder feed bed, has been evaluated, using a number of particle size fractions of material. Existing theories suggested that the bulk den...
