Abstract

Abstract Deep fat pressure cooker apparatus including a power-driven cover that coacts with the cooking vessel in the manner of a piston and a cylinder to enable both the closure of the vessel and also the compression of the contents of the vessel to pressurize the latter. The apparatus also includes a food basket that is releasably coupled to depend from the cover, and which basket, if previously positioned in the vessel, is automatically coupled to the cover on the subsequent lowering of the latter. The apparatus can be employed to practice several novel cooking methods. In one of these methods, the cover and the basket (the latter containing the foods to be cooked) coupled thereto are simultaneously lowered to simultaneously immerse the foods in a preheated cooking oil or fat while closing and compressing the contents of the vessel to pressurize such contents. In another method, the basket with foods therein are placed in the vessel and immersed in the preheated cooking oil or fat, and the cover is thereafter lowered to close and to pressurize the contents of the vessel, with the basket being then automatically coupled to the cover. In yet another method, the basket is initially immersed in the preheated cooking oil or fat, with the food then being dropped into the basket and immersed, with the cover thereafter being lowered and coupled to the basket.

Claims Analysis

Total Claims: 1
Claim 1
Independent Claim 115 words
In the method of deep-fat pressure cooking of moisture containing food, wherein the pressure within a confined zone is initially increased from atmospheric pressure to a superatmospheric cooking pressure by the evolution of water vapor from the food resulting from the latter being contacted by a cooking liquid having a temperature substantially in excess of 212* F., the improvement comprising the step of reducing the volume of the confined zone as the pressure within the confined zone is increasing above atmospheric pressure, whereby the initial increase in pressure within the confined zone is in part due to compression with consequent conservation of the moisture content of the food in effecting cooking pressure within the zone.
