  • Patent number: 5454295
    Abstract: A method and an oven are disclosed which provide reduced baking times for pizza. The method includes the step of impinging the toppings portion of the pizza with jets of heated air. These jets of heated air have a velocity at the point of contact with the pizza sufficient to cause temporary displacement within the toppings portion. As a result, the time needed to properly bake the pizza is reduced. The oven includes means for impinging the toppings portion with jets of heated air at a velocity sufficient to cause temporary displacement within the toppings portion. The oven also preferably includes means for moving the pizza in relation to the jets of heated air. Preferably, the method is practiced and the oven is provided by modifying a commercially available pizza impingement/conveyor oven to produce the requisite heated air velocities.
