Abstract: Apparatus for stuffing pitted olives with an edible filling features a drum and drum holder, plus drive means for rotating the drum holder and drum about a selected rotational axis. Pitted olives are placed in a drum along with a quantity of filling, then the drum is rotated, agitating the olives and filling in tumbling fashion, and causing the filling to work its way into the cavities in the olives. The invention facilitates stuffing of large quantities of olives at one time, rather than individually, without manual contact with the olives or the stuffing materials. Effective stuffing may be accomplished with a variety of filling materials. The efficacy of the stuffing process may be enhanced by imparting reciprocating motion to the drum in addition to rotational movement, and by providing protuberances on the interior surface of the drum.

Abstract: A mixing device includes a plurality of elongated ampules mounted on a rotatable support with the longitudinal axis of each ampule inclined inwardly toward the rotational axis of the rotatable support. When the mixing device rotates about the rotational support, centrifugal force causes fluid in each ampule to move toward the end farthest away from the rotatable support.

In one embodiment, the rotational support is inclined so that the end of each ampule positioned farthest from the rotational support is positioned sufficiently above the other end so that the bubble rises to the end farther from the support in at least one position as the support rotates. As a result, a bubble in each ampule moves back and forth between the ends of the ampule as the rotatable support rotates to mix respective fluids in the ampules.
