ABSTRACT:
An apparatus for coating molds to make hard gelatin capsules has a dish for holding a bath of liquid gelatin. A multi-well tray is submerged in the bath to establish a plurality of fluid passageways through the bath and to create a pool of liquid gelatin in each of the wells. A drive unit, having a pair of counterrotating gears, moves gelatin through the passageways and pools to maintain a substantially uniform gelatin temperature throughout the bath. Capsule molds are periodically submerged into the pools and then withdrawn to manufacture the hard gelatin capsules.
