Rotary cutting apparatus

Abstract

An improved rotary cutting apparatus is provided for cutting vegetables, particularly such as potatoes, into a distribution of strip sizes not exceeding a predetermined length limit. The apparatus comprises a conventional rotary impeller having peripheral blades for carrying potatoes into cutting relation with a slicing knife on an impeller housing for dividing the potatoes into slices followed by subsequent cutting into strips by strips knives on an adjacent cross-cut spindle. The impeller further includes an axially centered divider ring defining a pair of annular chambers for potato passage outwardly to the slicing knife, wherein longer potatoes are required to orient with their longitudinal axes extending generally radially with respect to the impeller, and generally perpendicular to the slicing knife, to limit the maximum length of the cut slices and the resultant cut strips. Arcuate paddles can be installed in association with the impeller blades to further improve potato alignment, and axial shims can be used to tailor the specific axial dimensions of the annular chambers.
