Abstract: An improved impeller assembly for use in a vegetable cutter comprises a series of equally spaced impeller blades radiating from a central shaft. The blades of the impeller curve around the shaft as they extend along the shaft to form curved, cupped sections of the blade. The impeller assembly rotates within a hollow drum and the blades urge vegetables within the drum against a slabbing knife having its cutting edge positioned within the drum. The curve of the impeller blades is such that when vegetables are introduced into the drum, the impeller blades curve away from the vegetables. The force with which the vegetables contact the blades is thus reduced so as to avoid bruising the vegetables. The shape of the impeller blades also serves to properly align the vegetables within the drum prior to slicing. In a preferred embodiment, the interior of the drum has a series of grooves formed therein to assist in aligning the vegetables prior to cutting.
