  • Patent number: 5417150
    Abstract: A pizza mold for forming pizza dough includes a frame having a peripheral configuration which matches the desired peripheral configuration of the dough, e.g., round, rectangular or square. One surface of the frame includes a plurality of concentric cavities formed at predetermined radial distances from the geometric axis of the frame, with one concentric cavity being formed adjacent the peripheral edge of the frame. The frame is designed to be brought into contact with the dough and the dough is formed (e.g., rolled) across the surface of the frame with the dough being formed in the concentric cavities. When the pizza mold is removed, the concentric cavities produce raised ridges of dough on the surface of the dough. The cavities can be formed in rings across the surface of the frame to create annular raised ridges for a round pizza, or the cavities can be formed in rectangles or squares across the surface of the frame to create rectangular or square raised ridges for a rectangular or square pizza.

  • Patent number: 5196217
    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 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. The section also has a grid of openings formed therein.

  • Patent number: 5069914
    Abstract: A hot dog or other elongated food product having generally longitudinal slits extending along the entire length of the hot dog. The slits are preferably spaced around the circumference and extend radially from the outer surface toward, but not completely to, the center of the hot dog, thereby forming elongated segments, each having a cross section in the shape of a sector of a circle truncated at its apex. The unslit central core comprises a common link between the truncated sector shaped segments, which initially holds the segments in a generally unitized hot dog-shaped construction, any section of which readily fragments into small sized segments when severed from the whole by a bite which extends through the central core.

  • Patent number: 4751093
    Abstract: The object of the invention is to enable the preparation of fried potato products with improved texture and texture stability.Potato pieces, such as strip-shaped French fries or disc-shaped dinner fries, have better inner and outer textures and retain a desirable textural contrast between the two longer after finish frying where the surface of the potato pieces is disrupted, preferably in combination with a blanching step and most preferably when done after a surface skin has been formed by air drying or par frying. Improvements are also seen where the pieces are blanched sufficiently to substantially completely gelatinize the potato starch and preferably are infused with low molecular weight soluble solids and then washed sufficiently to remove some of the soluble solids. The soluble solids, such as sodium chloride, within the potato pieces help to hold moisture internally of the pieces and to retard its exit through the crisp surface skin formed by frying.
