  • Patent number: 5045329
    Abstract: After pita dough has been rolled and prior to baking of the dough to form pita bread, the flat pancake-like dough form is weakened along a perforation or score line on at least one side of the dough form. In the baking process the dough form seals and inflates to form the central void characteristic of pita bread. The perforation or score line forms a weakened section in the inflated skin of the baking dough so that the rupture of the pita skin during the baking process occurs preferentially at the perforation or score line. The pita bread which results from this baking process is easily torn at the perforation or score line. Since the perforations cause the baking-caused rupture to be located at the tear line, the pocket formed by the pita bread when it is torn and opened by the user will not include a baking-caused rupture.

  • Patent number: 4837382
    Abstract: A mass of flowable food material is extruded to form a moving, continuous, flexible extrudate ribbon that is cured to form a continuous, semi-rigid ribbon. During curing, the ribbon is fed between a pair of pull rollers that pull the ribbon at a rate of speed that is faster than the extrusion rate of the ribbon, to thereby stretch the ribbon while being cured into semi-rigidity. The semi-rigid ribbon then is fed between a cutter roller and an opposing backup roller, the cutter roller including outwardly projecting, transversely mounted blades with edges that bias against an outer support surface of the backup roller during cutting. The opposing cutter and backup rollers rotate at substantially the same speed as the pull rollers to cut the semi-rigid ribbon with cuts that are substantially perpendicular to the direction of ribbon travel, thereby forming individual food pieces having substantially planar cut faces.

    Abstract: Disclosed is a pneumatically powered automatic apparatus and method for subdividing one or more loaves of dough supported in a partitioned single use, nonmetallic tray at a processing station intermediate the opposite ends of a conveyor. A tray of dough is introduced into the apparatus as a tray of subdivided dough exits onto the conveyor. The dough subdivider functions to draw the skin of the roll of dough from the upper and lower sides thereof permanently into closely spaced relation between adjacent subdivisions of dough thereby leaving the subdivisions connected solely by a web which is readily frangible when the dough is baked. The dough subdivider operates dry and free of lubricant. Trays of dough exiting from the apparatus are maintained frozen and wrapped until ready for the oven at either a local or a distant comsumption site.

  • Patent number: 4808104
    Abstract: An illustrative embodiment of the invention comprises an annular device for preparing pie crusts in which the inner margin of the device defines the central, circular opening. The margin, perpendicular to the base of the device, also forms a cutting edge that slopes away from the opening and toward the base until it intersects a flat working surface for the device. An arcuate surface, curving from the working surface to the base enables the device to be positioned on a breadboard with the cutting edge oriented in the proper direction. By rolling dough deposited in the opening, the opening fills up to the margin and surplus dough flows over the cutting edge and onto the working surface, the cutting edge severing the surplus dough from the shaped mass in the opening. The device, with surplus dough, is lifted smartly away from the breadboard, leaving a circular pie crust of uniform thickness defined by the marginal distance between the base and the crest of the cutting edge.

  • Patent number: 4786517
    Abstract: Dough pieces are produced in high volume by a plurality of dual extruders spaced across a conveyor and each having a pair of extrusion nozzles aligned in the direction of conveyor travel. A cut-off mechanism severs the dough extrusions to deposit dough pieces on the conveyor. The speed of the conveyor is related to the speed of the cut-off mechanism so that the dough pieces produced by each extruder form a single uniformly spaced line. The extruders are fed from a common supply through individual inlets and means are provided to balance the flow through the nozzles.

  • Patent number: 4741916
    Abstract: A method of and apparatus for making individual dough pieces that are of substantially constant size and shape. The method includes the steps of forming a continuous dough rope and laying it on a horizontally-moving conveyor belt. The rope then passes between a pair of horizontally-reciprocating cutting elements which, when closed, cut a dough piece form the rope's end portion. The closed pair of cutting elements also forms a mold having an open top. While the dough piece is momentarily within the mold, a tamping plate is brought vertically downward into contact with the piece, thereby giving it a preselected size and shape. In another particularly preferred embodiment, a channel is formed in the continuous rope's top surface that is subsequently filled with discrete morsels. When the tamping plate is brought into contact with the dough piece, the plate presses the morsels firmly into the dough piece's outer surface.

  • Patent number: 4734293
    Abstract: The invention relates to a method of dough moulding and a machine for carrying out the method, and in particular, is concerned with cross-panning of the dough piece. One or more incisions are made in the dough piece so that it can be folded, and according to the method of the invention, after the incisions have been formed, the dough piece travels to the dough folding station between a moving element and a stationary control member (which may be a spring loaded control plate) so that the dough piece is forced to turn about its longitudinal axis. The length of this control movement is so arranged that the angular displacement of the dough piece causes the dough hinge or hinges to be in a desired orientation when the dough piece arrives at the folding station. In W-folding the center dough hinge is displaced from the side dough hinges by 180.degree.
