Abstract: A dragee-making drum cooperating with a partition wall in order to promote cleanliness, particularly during the manufacture of medical preparations, by increasing the isolation between the clean "grey" zone in front of the partition wall and the dirtier "black" zone behind it. This increased isolation is accomplished by providing a flanged rim at the mouth of the drum to fit within a corresponding U-shaped seal disposed at the opening of the partition wall. An opening is provided at the bottom of the seal for removal of debris.
