US Patent:

50091417, Apr 23, 1991

Filed:

Sep 23, 1985

Appl. No.:

6/779209

Inventors:

John C. Julian - Tualatin OR
David S. Phelps - Tigard OR

Assignee:

Lamb-Weston, Inc. - Tri-Cities WA

International Classification:

B26D 102

US Classification:

83857

Abstract:

An apparatus for slicing food products, including potatoes and the like, includes a plurality of perpendicularly intersecting knife blades of chevron configuration which are arranged in a substantially pyramidal formation. The apex of the pyramidal formation and apexes of the individual blades point downstream, away from the direction of flow of a fluid stream which carries the potatoes toward the knife assembly for slicing. The blades are mounted by a unitary fixture having a cylindrical bore and mounting the blades such that the farthest upstream blades are spaced farthest away from the axial center of the blade assembly, with successive downstream blades being spaced incrementally closer to such axial center. The blades are further mounted such that no parallel blades axially overlap one another.

International Classification:

B26D 328

US Classification:

83403

Abstract:

A knife assembly for a potato slicing machine used in slicing potatoes into waffle or lattice cut sections includes an elongated, corrugated knife and inner and outer clamping members for clamping the knife therebetween. The inner and outer clamping members each have a plurality of parallel, tapered fingers which extend toward a cutting edge of the knife along grooves in one side of the knife, thereby to support both sides of the knife and lift potato surfaces away from such side and any potential interfering edges which might shear away portions of the cut potato surfaces. A unique potato product formed using such knife assembly is a substantially ellipsoidal section having a peak to peak thickness of about 7/16 inch. The section has opposite sides, each with longitudinal ridges and grooves therebetween. The ridges and grooves of one side are disposed at an angle to those of the other.

A unique potato product formed using such knife assembly is a potato section having a peak to peak thickness of about 4/16 to 10/16 inch. The section has opposite sides, each with longitudinal ridges and grooves therebetween. The ridges and grooves of one side are disposed at an angle to those of the other.
