Abstract: A process for splitting pistachios including a bin dumper, a sizer, moisturizers, blowers and splitting units arranged in seriatim. The blower removes excess water and particles from the nut surfaces after moisturizing and before splitting. The splitter includes a controlled surge bin having a brush gate associated with a sensor to control flow to a singulator. A vibrated singulator operates to release nuts to a splitting mechanism having opposed elements with cavities aligned to receive the ends of the nuts. Cradles retain the nuts in alignment for compression. Lateral vibration is induced in the cradles to ensure placement of the retained nuts.
