Abstract: The present invention relates to a device and method for capsule filling machines that employ a vertically rotating drum containing a plurality of cavities wherein each cavity is designed to receive a single minitab for transport to a capsule shell body.

Abstract: A particle conveying apparatus includes a transfer tube defining a flow passageway between inlet and outlet ends and defining a flow axis and includes a housing adapted for connection with a source of fluid pressure and for directing fluid from the fluid pressure source into the flow passageway between the inlet and outlet ends whereby the directed fluid travels spirally along the flow axis toward the outlet end. The housing defines a generally toroidal chamber surrounding the tube, the tube having an angled flow control slot providing communication between the chamber and the flow passageway, and the pressurized fluid is directed tangentially into the chamber to cause the fluid to enter the flow passageway through the slot in a spiraling direction toward the outlet end.
