Abstract: An apparatus for removing pits from prunes or other soft fruit, including holders defining pockets for holding soft fruit, an excess fruit removal assembly (e.g., comprising one or more paddle wheels), a pitting knife assembly, and a holder drive assembly for translating the holders along a closed loop. Each pocket defined by each holder is movable between open and closed configurations as the holder is translated around the loop. Each holder includes a top chuck plate shaped to guide an article of fruit into each pocket with reduced risk that excess fruit (fruit not properly seated in a pocket) will remain lodged on the chuck plate after the holder has translated past the excess fruit removal assembly. Other aspects are a chuck plate configured for use as a top chuck plate of a fruit holder of a pitting apparatus, and a fruit holder including such a chuck plate.

Abstract: A pitting knife assembly including a pitting knife mount and a pulley drive assembly coupled and configured to move the knife mount around a circular or substantially circular path, and a fruit pitting apparatus including such an assembly. During operation of the pitting knife assembly with at least one pitting knife mounted to the knife mount and a fruit conveying assembly positioned to convey fruit to the pitting knife assembly, the pitting knife can produce pitted fruit by moving into engagement with fruit conveyed by the conveying assembly (to pit the fruit) as the knife mount moves through a first portion of the path, and the pitting knife can then move out of engagement with (and away from) the pitted fruit as the knife mount moves through a second portion of the path.

Abstract: A cherry pitter includes a container having a removable cherry holder with a plurality of cavities for holding cherries. A mating plurality of cutters is secured to the lid of the container, which is pivotally secured to the container. By rotating the lid downward the cutters are pushed into and through the cherries, pushing the pits into the container. A spring-loaded push-off plate holds the cherries down against the holder as the lid rotates upward again, separating the cherries from the cutters. These and other examples of the invention will be described in further detail below.

Abstract: Described is a pitting machine, system and process that singularizes or individualizes fruit pieces, such as cherries, olives, dates and plums and that attempts to remove pits and pit material from each fruit piece. A conveyor comprises depressions, wells or receptacles for accepting fruit pieces for processing. The conveyor accepts fruit pieces into wells, passes the fruit pieces into a pitting area wherein the pitting machine removes pit material from the fruit pieces by a matrix of punching needles or pitting needles. The matrix moves in an oscillatory fashion in synchronization with generally continuous movement of the fruit pieces engaged in the conveyor. The singularization enables easier and better processing, sorting, and quality checking of fruit pieces. Quality checking may be done before and after pitting of fruit pieces. Quality checking may include desired color and size of each fruit piece. Quality checking virtually ensures successful or sufficient removal of pits and pit material.

Abstract: A pitting machine comprises a punching head that performs a curvilinear oscillatory movement in synchronization with the translation movement of fruits to be pitted, in particular for use in industries that process food such as pitted dried or dehydrated plums and which are currently performing manual operations or using rudimentary equipment.

Abstract: A drupe which is infested with a larva of a moth or larvae of other insects, and is contaminated with related excretions, referred to as a “frass”, in a central zone within the drupe, is cleansed with a longitudinally bored pitting knife mounted in the pitting head of a conventional pitting machine. A source of cleansing fluid is connected to the bore within the knife and fluid is discharged through radial passages in the knife, which radial passages communicate with the longitudinal bore. In operation, while the knife pits the drupe, fluid discharged from within the knife contacts the walls of the passage left by the ejected pit, and removes the frass. If desired, the drupe may be first pitted, then decontaminated or washed, and/or dried sequentially, in separate stages. The invention is particularly effective with dates, prunes, olives, cherries, nectarines, peaches and avocados.

Abstract: A fruit pitting apparatus including at least one of a box cam assembly for driving pitting knives relative to holders containing fruit, an active separating assembly which improves the efficiency of separation of the pitted fruit flesh from the holders after pitting, and a wiping blade positioned to wipe pits from the holders after pitting. The holders can be driven continuously during the pitting operation, or they can be driven intermittently so as to be stationary during pitting and to translate before and after pitting. The separating assembly preferably includes actively driven cam tracks within the knife driving assembly which vary the force with which the holders grip the fruit during and after pitting, especially when the holders are driven intermittently.

Abstract: A pitting knife drive assembly for mounting in a fruit pitting apparatus to drive pitting knives of the pitting apparatus. The pitting knife assembly includes a box cam, a drive assembly for rotating the box cam, a pivot unit which undergoes reciprocating pivoting motion in response to the rotating box cam, and a set of one or more shafts which reciprocate longitudinally in response to the reciprocating pivoting motion of the pivot unit. Preferably also, the pitting knife assembly includes a subassembly for causing the shafts to undergo reciprocating motion in directions perpendicular to their longitudinal axes. A preferred implementation of this subassembly includes a carriage driven by a rotating eccentric, where the eccentric and the box cam are mounted along a common drive shaft, and the drive assembly includes a motor for rotating the drive shaft.

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).

Abstract: Fins have edges which extend forward from a body which is reciprocated back and forth by a driving rod. The fins also have cutting blades. Olives are depitted by causing the forward edges to penetrate the olives and engage the pits. The cutting blades then slice the depitted olive into separate disconnected slices.

Abstract: A method and apparatus for pitting olives and then slicing the pitted olives. In a preferred embodiment, each olive is carried in a cup positioned between a coring knife and a pitting knife in a manner so that the longitudinal axes of the cup and the knives coincide. As the cup and knives rotate around a drive shaft along parallel circular paths, a system of cams extends and retracts the knives relative to the cup, in order to pit the olive. After the pitting operation, the cup (containing a pitted olive) continues to rotate along its circular path past a set of slicing knives. The slicing knives are oriented substantially parallel to the plane of the cup's circular path, so that the slicing knives act as wedges to sever the olive cleanly into slices as the cup translates past the slicing knives. In the inventive method and apparatus, both the pitting and slicing operations are performed on each olive while the olive is held in a known orientation.

Abstract: A turntable with olive cups is advanced stepwise by a suitable Geneva movement. At a feed station unpitted olives are delivered into the cups. Between the feed station and the pitting station the cups are vibrated to properly orient the olives for pitting. After pitting, the olives are stuffed with pimento, the pimento feed system including toothed drive means for a continuous pimento strip, a feed chute which serves to fold the strip in half along its lengthwise centerline, and cut-off knives to sever the strip into sections for stuffing.
