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.
