Abstract:
A browning grill is arranged for use in a high power density radiant oven. The oven includes a cooking enclosure having a ceiling and a floor, upper radiant energy sources located near the ceiling, and lower radiant energy sources located near the floor. The browning grill has a grilling surface and a debris collector. The grilling surface has a plurality of grill tines. The grilling surface is located between the upper and lower radiant energy sources, and the grilling surface establishes a cooking plane to the upper radiant energy sources. The debris collector catches food debris from food being grilled on the grilling surface. The debris collector is located between the grilling surface and the lower radiant energy sources, and the debris collector is arranged to permit heating of the cooking plane by the lower radiant energy sources.
Abstract:
A microwave intensification system includes a base frame having a plurality of support members, a microwave transparent, central vessel, and at least one dielectric unit positioned within the central vessel. A cooking surface is formed by covering the dielectric unit with a protective covering. In operation, a food item is placed within a processing container and positioned on the cooking surface over the dielectric unit. The processing container is sized such that an overlap exists between the container and the dielectric unit in order to balance the exposure of the food item to a microwave energy field. With this arrangement, the food item can rapidly undergo a cooking process in a manner wherein central and edge portions of the food item are exposed to a uniform cooking process thereby increasing the quality of the final product.
Abstract:
A compact oven assembly has a housing and a high power density, low mass heating element. The housing defines a cooking cavity and a slot which permits access to the cooking cavity. The high power density, low mass heating element is supported by the housing above the cooking cavity. The compact oven assembly may include a food support which is arranged so that, when the food support is inserted into the cooking cavity through the slot, the slot of the housing is substantially closed off. The compact oven may also include a switch operated by the food support when the food support is inserted into the cooking cavity through the slot in order to energize the high power density, low mass heating element. Each high power density heating element has a formed parabolic reflector located above it and opposite to the cooking plane. Accordingly, the energy from the high power density heating elements is directed toward the cooking plane. The location of food and the position of the high power density heating elements within their corresponding reflectors are important to assure both optimum power density and uniformity of energy distribution over the cooking plane.
Abstract:
A method for the manufacture of a screen useful for forming three-dimensional films, the screens and the three-dimensional films produced using those screens are disclosed. In forming a screen, a substrate material is applied to a base. A predetermined amount of portions of the substrate are removed to form a predetermined pattern in the substrate. A screen material is applied to the patterned substrate material. A predetermined amount of portions of the screen material are removed to form a predetermined pattern in the screen material. The predetermined pattern in the screen defines a plurality of first perforations in the screen material. The substrate material is removed from the screen material, such that second perforations are formed in the screen, whereby each first perforation is in communication with an adjacent second perforation.
Abstract:
An oven with high power radiant cooking elements which are capable of operating at different intensities is disclosed for cooking food quickly with infrared radiation. The conduction of this infrared radiant energy varies substantially from food to food. Accordingly, the user of the oven must develop a unique data base or recipe for each food. A recipe consists of a number of stages each of which defines the output intensity of each cooking element for a period of time. A method is disclosed for the real time development of a recipe by varying the intensity of the cooking elements during the cooking cycle, optimizing the developed recipe to reduce the number of stages, storing the optimized recipe in memory and retrieving the optimized stored recipe for future use.
