David Z. Ovadia has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9491957
    Abstract: A method of making a cooked food product having a fried appearance comprises assembling a food product having a weight of approximately 1 to 4 ounces (28.3 to 113.4 grams). The food product is heated with microwave energy at a frequency of approximately 800 to 3000 MHz, at a power of approximately 0 to 50 Watts per ounce (28.3 grams) of product, and for approximately 0 to 80 seconds. The food product is coated with a coating layer to form a coated food product. The coated food product is heated in an impingement oven at a temperature of approximately 400 to 600° F. (200 to 325° C.) for less than approximately 140 seconds to form the cooked food product with a fried appearance.

  • Patent number: 6320165
    Abstract: Embodiments of the present invention can be used in situations in which heat and mass-transfer modified product, such as individual-sized pizzas, are to be prepared in relatively short periods of time, for example in one to five minutes. Through structural design features and air manipulation, embodiments of the invention provide distinct advantages over the prior art, including improving quality control by increasing uniformity of heating across the oven and within each particular product, decreasing required baking time by increasing the effectiveness of impinging air jets through air pulsation and fluctuation, and maintaining uniformity of air flow to contact the baked product substantially perpendicular to its surface. Tubes or pipes possessing impingement nozzles permit the use of compressed air instead of fans. Embodiments of the invention permit more compact oven design, better control of air jet parameters, and quieter oven operation, and other advantages.

  • Patent number: 6054697
    Abstract: Pizza pan shielding systems and methods generally include one or more of the following: a pan, a bottom shield, a top shield, and a ring shield. Each of these elements preferably incorporates a plurality of perforations. The size, location and density of these perforations, and/or the material make-up of the element(s), determine whether certain types of baking energy from various heat sources will reach a food item located within the system. Substantial evenness of cooking results, in a short time period and at reasonably baking temperatures. Embodiments of the invention address the problems of underbaking in central areas of the food item and overbaking, dryness, microwave-induced toughness or burning of outer areas of the food item, such as a crust area. Embodiments of the invention have particular, though not exclusive, application to the pizza-baking devices and methods.
