Abstract: An Avocado Skinning and Pulping Device. The avocado pulper has two grip belts approximately oval in shape and further having a plurality of grip plates around the grip belts. The grip plates are knurled thereby facilitating a grasping of an avocado as it is conveyed into the grip belts and rides through to the rear opening. A pivotable and adjustable belt guide within an inner section of each grip belt is adapted to exert maximum squeezing pressure on the avocado at the approximate middle section of the grip belts at which point the grip belts are in approximate contact with one another. Pulp is thereby squeezed from the avocado. The grip belts separate at the approximate rear defining space for releasing the skin of the avocado. A de-seeder adjacent to the front end opening of the grip belts removes the seed from the avocado prior to its entry into the maximum squeezing section.

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 floatation separation method is described for separating pieces of fruit or vegetable of the same type, but wherein desirable pieces have a slightly different specific gravity from the undesirable ones, and all have a specific gravity about the same as that of water. The pieces (12, FIG. 3 ) are placed near the surface of a body of water, and a cloud (40) of tiny air bubbles is maintained in the water. As the bubbles float to the surface they encounter the articles and slightly increase their buoyancy. The increase in buoyancy is slight and uniform, so those articles having a density slightly greater than that of the water will remain at the water surface, while those of a slightly greater density cannot be floated by the air bubbles and will sink to the bottom. The cloud of air bubbles is created by allowing air at about atmospheric pressure, to emerge from apertures in a rapidly spinning rotor that open in a direction primarily opposite to the spin direction.

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 or water jet cutters. The slicing elements are oriented substantially parallel to the plane of the cup's circular path, so that the slicing elements will sever the olive cleanly into slices as the cup translates past them. 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 method and apparatus for pitting olives, in which each olive is held between a pair of matching knives as the knives are rotated along parallel circular paths by a rotating drive shaft. The knives may both be coring knives or may both be pitting knives, and are aligned so that their longitudinal axes coincide and the common longitudinal axis is substantially perpendicular to the plane of the olive's circular path. As the knives rotate along parallel circular paths, they are translated by cams along their common longitudinal axis so as to penetrate opposite ends of the olive simultaneously and then to push the pit out through one end of the olive. The coring knife embodiment of the invention leaves a clean bore through the pitted olive after removal of the core (including the pit), and prevents the pit from tearing away an irregularly shaped olive portion during removal.

Abstract: A method for depitting an olive wherein at least one elongated member moves horizontally through an olive having a horizontal longitudinal axis and supported at one end in a recess of a cup to force the pit through a central opening in the recess.

Abstract: Improvements to a torque-type peach pitter and method, during each cycle of which a peach is presented to a pair of peach bisecting and pit gripping blades for cutting the flesh of the peach to its pit at its suture plane and gripping the edges of the pit to hold it stationary and wherein the peach halves are twisted to separate them from the held pit. The improvements reside in a pre-slitter blade positioned to cut a portion of the peach flesh at the suture plane prior to its presentation to the peach bisecting and pit gripping blades.The peach pitter includes a normally inoperative curved spoon which is extended upon the detection of a split or defective pit and serves to cut such pit from the peach. The pre-slitter blade detects the absence of a peach in any pitting cycle and triggers means to disable the spoon operating mechanism so that the spoon will not be extended during such cycle.

The row of tines has tines of lesser length in mid-portion to accommodate the stone and an overhead moveable bar carries a mating row of tines that pierce the fruit above the stone. This bar can be carried on a strike arm adapted to engage a strike plate on one of the platform halves and force the platform to open when the bar is forced downwardly as by being struck smartly with the hand.

Abstract: Pitted olives are stuffed with an edible food that has been dried to facilitate its handling, and the dried food is reconstituted within the pitted olives by packing the stuffed olives in an aqueous solution. Drying an edible food, such as pimiento, is carried out to cause an increase in stiffness and a drying of the surface texture to permit gripping of the food without slipping. Also, a reduction in size will accompany the drying of the food particularly if air drying is used. With this reduced size condition of the food, greater clearance can be allowed between the walls of the olive pit cavity and the sides of the food to be inserted since the food will swell to a tight fit within the pit cavity upon subsequent reconstitution. The stiffness of the dried food will be greater than that of the olive adjacent the walls of the pit cavity so that the walls of the pit cavity will deflect outwardly to receive the dried food if the dried food is somewhat oversized or slightly out of alignment.
