Abstract: A method and apparatus are disclosed for detecting the presence of steam in a volume of air at a predetermined temperature. The apparatus includes a temperature sensor having two respective temperature build-up times representing an under steam temperature build-up time and an under air temperature build-up time. The method for detecting the presence of steam comprises the steps of placing the temperature sensor in the presence of the volume air, such that the sensor can reach a predetermined set point temperature that is lower than the predetermined temperature, taking a temperature measurement with the sensor, and determining if the measured temperature reaches the set point temperature in order to indicate whether the sensor is in the presence of steam.

Abstract: Various representative commercial cooking devices are disclosed wherein a recirculating flow of heated air, at a food cooking temperature, is created within a housing in which a horizontally disposed food support and cooking member, such as a perforated metal plate, a solid griddle plate or a metal broiling grate, is positioned. A plenum structure is utilized to convert a portion of the continuously recirculated air into a spaced series of relatively high velocity heated air impingement jets which are caused to laterally diffuse and at least slightly overlap prior to striking at least one side surface of the food support structure. In this manner, each food support structure side surface subjected to such diffused jet impingement is evenly blanketed with heating air to thereby very uniformly transfer heat from the air to the food support structure, and thus to the food supported thereby, at an accelerated rate.

Abstract: A steam generator for a convection oven through the oven chamber of which heated air is circulated by means of a fan along a flow path in which the steam generator is positioned, comprises a heat-storage unit having a stack of elongated horizontal supports for supporting ball-shaped heat-storage bodies and means for spreading water over the heat-storage unit. Each support includes a bottom wall having a plurality of polygonal apertures which form seats for respective ones of the heat-storage bodies. The apertures, the size of which is substantially smaller than the largest cross-section of the heat-storage bodies, form flow passages through which water from overlying supports is passed to the top portion of the heat-storage bodies of underlying supports.

Abstract: A swivel-truck bakery oven having a baking chamber, a charging door, an electric control box, a recirculation channel, a re-circulation fan, heating elements for heating the re-circulation air, mechanical and power equipment for rotatably driving the swivel truck, and a blowing manifold with vertical louvres and a steam generator. The oven consists primarily of a generally rectangular frame structure, with the frame structure having a central core of parallelipipedic configuration with a width substantially corresponding to the width of the charging door, which is determined, in turn, by the width of the swivel truck. The frame structure also has a pair of detachable lateral covers which each have an interior recess or cavity of a depth that is slightly greater than half the difference between the width and the diagonal length of the swivel truck.

Abstract: An oven is described which is especially adapted to maintain accurate and uniform temperature control. The device of the invention includes a central treatment chamber surrounded by a plenum chamber which, through a number of spaced apart apertures introduces gases at a preselected temperature and elevated pressure into the treatment chamber. The plenum chamber is configured to insure a substantially uniform pressure at each of the apertures to provide a uniform flow of temperature regulated gases through each of the apertures.

Abstract: An improved air delivery system is provided for an impingement food preparation oven including a plurality of air ducts disposed in a cooking chamber, a plenum connected to the air ducts, and a scoop-type fan disposed in a backwall opening of the plenum to provide a flow of heated air smoothly and uniformly through the plenum into the air ducts. The fan device includes a plurality of tear-drop shaped blades, wherein each blade has a leading edge portion that tapers to a point in the direction of rotation and a trailing row portion at a given pitch angle for forcibly moving the flow of air in an axial direction toward the plenum front wall. The plenum front wall has a plurality of openings connected to the duct members, and a multi-tapering surface tapering from the front wall openings inwardly of the plenum toward the fan, whereby the axially directed flow of heated air from the fan is smoothly and uniformly directed by the multi-tapering surface to the plurality of air ducts, thereby providing a uniform cooking temperature in the cooking chamber.

Abstract: An improved steam heating apparatus is provided for top heating of food items such as pastries, rolls, sandwiches or the like to render them appetizing in appearance and taste, and, in particular, for melting garnishes or toppings such as cheese on food items and simultaneously heating the food item prior to serving. The top-firing steamer comprises a generally flat, heated, steam-generating platen which defines a steam-generating chamber; a food steaming chamber located under the platen; and a plurality of raised perimeter apertures extending perpendicularly through the platen to allow steam to effuse downwardly from the steam-generating chamber into the food steaming chamber below, while preventing unvaporized water collected on the heated platen from draining into the food steaming chamber.
