ABSTRACT:
The present invention is directed to improving the conventional high-speed cooking oven based on a combination of hot air impingement and microwave heating by providing a time-dependent spatial variation in the net air impingement and/or net microwave energy applied to the food product in the oven. This is aimed at optimizing heat transfer and microwave efficiencies in a high-speed cooking oven, thereby enabling the oven to deliver an optimal cooking efficiency in comparison to the conventional high-speed cooking oven. In addition, under the present invention, the cooking efficiency may be further optimized by dimensioning the nozzles for hot air impingement to tighten impingement plumes, subject to the space constraint of the oven's cooking chamber, and dimensioning the cooking chamber of the oven in integer multiples of the wavelength of the microwave energy to match the microwave load. With the optimized cooking efficiency provided by the present invention, the high speed cooking technology may now be extended to ovens operating on a power supply based on a voltage less than 220 volts, preferably between 110 and 125 volts, with more productive results, so that the high-speed cooking technology may find a wider applicability and customer base.
