  • Patent number: 5919508
    Abstract: To facilitate baking a frozen dough product in an oven having a rack formed of aligned bars, the dough product is formed over an oven-safe paper sheet which has a plurality of die-cut holes. This sheet serves as a baking substrate and obviates the need for a baking pan. The paper sheet is formed with the dough product, and the dough extends through the holes and locks the sheet to the dough. The end user may thus remove the frozen dough product together with the sheet from a backing preform and place the assembly on an oven rack for baking. As the dough thaws the crust will loose its stiffness. The sheet however, will prevent the more pliable crust from distending through the oven rack before the dough has become baked and rigid. The sheet forms a backing which restrains flow of the dough, while at the same time the holes permit the escape of gases from the bottom of the crust and ensure uniform baking. Furthermore, the holes allow direct radiant heating of the dough product through the paper sheet.

  • Patent number: 5503860
    Abstract: Proofed dough is formed into pizza crusts which am formed and frozen without baking. The dough is positioned on corrugated paperboard preforms within a tray having multiple circular openings. The preforms have sidewardly opening corrugations. The trays are conveyed through the forming apparatus in a continuous process, with formed crusts being removed and fresh preforms being inserted. The preforms are positioned in a rectangular array within the openings in the conveyed tray. A quantity of raw dough is positioned on each preform within the tray. The dough is conveyed on the preforms beneath a bank of high pressure forming dies. The dies are pressed into the openings within the tray and over the dough to form the dough into the desired pizza crust shape. Each die extends between the preform and the tray within the opening to force portions of the dough into the preform corrugations to thereby secure the formed dough to the preform.
