Food processing apparatus |
(57) The present invention discloses an apparatus for slicing a food product such as a
potato into helical strips such as curlicue potato fries. The potatoes are pumped
with water by a centrifugal food pump to a tapered elastic tubular delivery tube.
The tube expands as the potato progresses along the tube. The delivery tube allows
the potato to be gently forced against a circular rotating cutting head assembly.
The cutting head assembly cores the potato, scores concentric cuts and then slices
the potato to produce helical cut segments.
