ABSTRACT:
A cherry pitter comprising a pitting station (24) adapted to support a cherry (88) having an opening 84 sized to allow passage of a pit (85), but not the cherry (88). A pit ejector (26) adapted to reciprocate along a longitudinal axis includes an elongate punch having a number of arms (50, 52, 54, 56) radiating out from the longitudinal axis, each arm extending beyond the proximal end of the punch to form a cruciform cross-section. One of the arms (56) has a substantially flat profile and the other three arms (50, 52, 54) have an undercut portion (66) of the same order of axial length as the diameter of a typical cherry. The punch is oriented so that the flat arm (56) projects towards a delivery passage (22). The delivery passage (22) has an arcuate channel that aligns the cherries and delivers them to the pitting station (24) one at a time. The elongate punch drives into the cherry (86) and pushes the pit through the outer flesh of the cherry (86) and through the opening (84) and into a pit chamber (94). The punch then pulls the cherry (86) back along the longitudinal axis so that the cherry (86) falls into a cherry bowl (13).
