| 20120085746 | Electric Broiler - A new electric broiler is disclosed. The broiler includes a housing having a cooking chamber, and a cooking surface in the housing. Upper and lower electrical heat sources are provided in the cooking chamber above and below the cooking surface. The lower heat source includes a removable heating module having an electric heating element and a quick connect/disconnect connector for quick electrical connection and disconnection of the electric heating element to and from a quick connect/disconnect connector on the housing. The broiler also includes a module holder on the housing for holding the removable heating module. The heating module is removable from the holder for quick replacement of the module. | 04-12-2012 |
| 20110226230 | APPARATUS AND METHOD FOR BLOCKING FLAME AND SPREADING HEATED GAS FROM A BROILER FLUE - Apparatus for substantially blocking flames and spreading heated gases emitted from a broiler flue. The apparatus includes a riser placed above the broiler flue for defining a pathway along which heated gases are exhausted from the flue, a catalyst support on the riser for supporting a catalyst in the pathway for flow of heated gases through the catalyst from a bottom surface of the catalyst to a top surface of the catalyst, and a plurality of baffles in the riser extending across the pathway below the catalyst support. The baffles have the shape of inverted troughs. | 09-22-2011 |
| 20110204755 | PRODUCT SERVER WITH BREATH GUARD - A product server for holding and displaying food products is disclosed. The product server has a front customer side, a rear employee side and a breath guard. The breath guard comprises a cover on a cabinet of the product server that is moveable between a lowered position covering the food products and a raised position in which the cover serves as a breath guard and allows access to the food products. Upright side panels are provided adjacent opposite ends of the product server. The breath guard extends between the upright side panels as it moves between its raised and lowered positions. | 08-25-2011 |
| 20100301034 | CONVECTION OVEN - A convection oven having a vapor collection system; water injection system; easily accessible electrical components; and a variable-speed, reversible blower is disclosed. 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. | 12-02-2010 |
| 20100293979 | FOOD SERVING BAR - A temperature controlled food serving having at least one channel of thermally conductive material for receiving at least one food-holding pan. The at least one channel defines an elongate pan receiving cavity for placement of the at least one food-holding pan at any desired location along the cavity. A temperature control system comprises at least one heating element for heating the at least one channel to maintain food products held in the food-holding pans at a food holding temperature. The at least one channel has at least two different temperature zones along a length of the channel so that food products in different temperature zones can be held at different food holding temperatures. | 11-25-2010 |
| 20100140252 | RETHERMALIZING APPARATUS - Apparatus for and methods of rethermalizing a package of refrigerated or frozen food are disclosed. In general, heating mechanisms are brought into conductive heat transfer contact with the package of food and operated for a duration of rethermalization time to rethermalize the package of food by heating the food to a rethermalized temperature, and then, if desired, to hold the rethermalized package of food at a desired holding temperature for a duration of holding time. The rethermalization time can be relatively short (e.g., thirty minutes or less), and the holding time can range from a very short period of time to a very long period of time (e.g., four, six, eight or more hours) without significant loss of food quality. Other features of the apparatus and methods are disclosed. | 06-10-2010 |
