Abstract
A counter-top oven adapted to effect low-temperature cooking of food at a relatively rapid rate whereby food nutrients and other valuable constituents are preserved. The oven includes a food-receiving compartment having a perforated wall and means to heat air to a temperature well above the cooking temperature of the food and to force the heated air through the perforations to cause the air to flow at high velocity through the compartment in heat-exchange relation with the food. This air flow is periodically interrupted to produce hot air pulses having no-flow intervals therebetween to create a laminar heat transfer pattern in which heat from the outer layer of the body of food is transferred to the intermediate layers and the core thereof in these intervals to a degree preventing the temperature of the outer layer from rising substantially above cooking temperature despite the much higher temperature of the air pulses whereby the intermediate layers and the core are caused to reach the cooking temperature in a relatively short period.
