Publication number: 20140144334Abstract: A system includes an oven and an apparatus configured for holding at least one food item and being inserted in a cavity of the oven through an open end of the cavity. A baffle provided on the oven or apparatus has a height extending between the peripheral rim and an upper wall of the oven cavity for restricting flow of gas out of the cavity from the apparatus. Various forms of baffles may be used. The baffles may have adjustable, interchangeable, fixed position, or other configurations.Type: ApplicationFiled: January 29, 2014Publication date: May 29, 2014Applicant: Duke Manufacturing Co.Inventors: Robert J.

Patent number: 8735778Abstract: A convection oven having a vapor collection system; water injection system; easily accessible electrical components; and a variable-speed, reversible blower. The vapor collection system collects vapor from the cooking chamber during a cooking event, condenses the vapor, and drains the condensed vapor. The water injection system injects water for impact against a blower wheel for dispersion into the air circulating through the cooking chamber. The electrical components are housed within a housing that in a closed position conceals the components and in a closed position exposes the components for easy access. The rotational speed and direction of the variable-speed, reversible blower is controlled during a cooking event according to predetermined speed curves which may include one or more reversal events to achieve more uniform cooking of food. A main controller is programmable via an operator input (e.g., liquid crystal display touch screen) to control operating parameters of the oven.Type: GrantFiled: February 15, 2013Date of Patent: May 27, 2014Assignee: Duke Manufacturing Co.Inventors: Jack Greenwood, Robert J.

Patent number: 8729429Abstract: A heated food storage and display cabinet including a flow inducer and heater arranged in an upper region thereof, the flow inducer being operable to draw air from an upper portion of the cabinet, to direct the air over the heater, and subsequently urge the heated air down the rear wall of the cabinet and across the floor of the cabinet towards the open front of the cabinet. The heated air is subsequently directed upwardly and rearwardly across the open front of the cabinet by an airflow direction member of the cabinet so as to provide a heated air curtain across the open front of the cabinet, and a portion of the heated air is also passed into the cabinet as the heated air moves down the rear wall and across the floor so as to pass over and around packs of food stored therein.Type: GrantFiled: November 8, 2010Date of Patent: May 20, 2014Assignee: Alan Nuttall LimitedInventors: Alan David Nuttall, Michael James Steele, Gareth Richardson
