Abstract

A system for producing par-baked pizza crusts from dough portions includes a pan adapted to support the dough portions. A lid assembly is positioned to contact each dough portion. The dough portions are par-baked in an oven, while the lid assembly contacts the dough portions, in order to produce par-baked pizza crusts.

Claims

1. A system for producing par-baked pizza crusts, comprising:

a mixer operable to mix a plurality of ingredients to produce pizza crust dough;

a sheeter operable to form the dough into a sheet;

a cutter operable to cut a plurality of dough portions out of the sheet;

a pan adapted to support a plurality of dough portions, the pan comprising a plurality of recesses, each recess adapted to receive a corresponding dough portion;

a proofer through which the pan travels to proof the dough portions;

a lid assembly positioned over the dough portions after the pan exits the proofer, the lid assembly comprising;

a frame comprising a plurality of elongate members; and

a plurality of lids mounted to the elongate members in an array, each lid being substantially separated from each other lid and corresponding to an associated recess of the pan; and

a first oven operable to par-bake the dough portions while the lid assembly is positioned over the dough portions to produce par-baked pizza crusts.

2. The system of claim 1, further comprising an oiler operable to deposit a layer of oil in the bottom of each recess of the pan before the dough portions are received in the recesses, the layer of oil contributing to the production of a bottom fried surface of the par-baked pizza crusts.

3. The system of claim 1, further comprising a lidding apparatus operable to position the lid assembly over the dough portions.

4. The system of claim 1, further comprising a delidding apparatus operable to remove the lid assembly from over the dough portions.

5. The system of claim 1, further comprising:

a first conveyor operable to convey the lid assembly for reuse after the dough portions have been par-baked; and

a second conveyor operable to convey the pan for reuse after the dough portions have been par-baked.

6. The system of claim 1, further comprising a second oven located remotely from the first oven, the second oven operable to produce a pizza for consumption by baking a par-baked pizza crust having a pizza topping.

7. The system of claim 1, wherein the lid assembly is of sufficient weight such that the lids compress the dough portions as the dough portions rise.

8. The system of claim 1, wherein the lids of the lid assembly include a plurality of apertures formed in the lids.

9. A system for producing par-baked pizza crusts, comprising:

a pan adapted to support a plurality of dough portions, the pan comprising a plurality of recesses, each recess adapted to receive a corresponding dough portion;

a lid assembly positioned such that it contacts each dough portion, the lid assembly comprising;

a frame comprising a plurality of elongate members; and

a plurality of lids mounted to the elongate members in an array, each lid being substantially separated from each other lid, each lid corresponding to an associated recess of the pan, each lid contacting a corresponding dough portion;

wherein the lid assembly further comprises a frame comprising a plurality of elongate members, the plurality of lids mounted to the frame in an array, each lid corresponding to an associated recess of the pan, each lid contacting a corresponding dough portion in the recess of the pan; and

an oven operable to par-bake the dough portions while the lid assembly contacts the dough portions to produce par-baked pizza crusts.

10. The system of claim 9, further comprising an oiler operable to deposit a layer of oil in the bottom of each recess of the pan before the dough portions are received in the recesses, the layer of oil contributing to the production of a bottom fried surface of the par-baked pizza crusts.

11. The system of claim 9, further comprising:

a mixer operable to mix a plurality of ingredients to produce pizza crust dough;

a sheeter operable to form the dough into a sheet; and

a cutter operable to cut the dough portions out of the sheet.

12. The system of claim 9, further comprising a proofer through which the pan travels for more than forty-five minutes to proof the dough portions before the lid assembly is positioned to contact the dough portions.

13. The system of claim 9, further comprising a lidding apparatus operable to position the lid assembly to contact the dough portions.

14. The system of claim 9, further comprising a delidding apparatus operable to remove the lid assembly from contact with the dough portions.

15. The system of claim 9, further comprising:

a first conveyor operable to convey the lid assembly for reuse after the dough portions have been par-baked; and

a second conveyor operable to convey the pan for reuse after the dough portions have been par-baked.

16. The system of claim 9, wherein the lid assembly is of sufficient weight such that the lids compress the dough portions as the dough portions rise.

17. The system of claim 9, wherein the lids of the lid assembly include a plurality of apertures formed in the lids.
