Abstract: A roller grill assembly includes a roller grill housing and a plurality of rollers that are rotatably mounted in the housing, each roller having an external surface. The assembly also includes one or more heating elements provided in each roller for heating the external surfaces of the rollers and a roughened coating overlying at least a portion of the external surfaces of the rollers, the roughened coating generating friction between the rollers and food items placed on the rollers for effectively rotating the food items. The roughened coating is food-safe and includes roughening particles having a size of between 5–300 microns.

Abstract: A combination roller grill and sneeze guard assembly includes a roller grill assembly having a top cooking surface, a sneeze guard securable over the top cooking surface of the roller grill assembly, the sneeze guard having an elongated groove formed in a top surface thereof, and a sign having a bottom edge secured in the elongated groove of the sneeze guard.

Abstract: A combination food preparation and self-serve delivery system includes a housing and a food preparation compartment located in a rear section of the housing, the food preparation compartment including a first heating element for heating food placed in the food preparation compartment. The system also includes a self-serve compartment located in a front section of the housing for holding finished food product, the self-serve compartment including a second heating element for heating the finished food product placed therein. The first and second heating elements are separate and are adapted to operate independently of one another.

Abstract: An electrically heated convection oven with built-in rotisserie for rotisserie roasting, baking, broiling, defrosting, and dehydrating foodstuff is characterized by the use of two motors. One for operating a fan which rotates within the heating chamber to create high velocity air flow throughout the heating chamber; the second one for rotating the rotisserie spit. The second motor is also utilized to drive a cooling fan that draws air over electronic controls to keep them safely cool. The electronic controls comprise a microcomputer which is pre-programmed to recognize input from a user and to process information from an air temperature sensor in the oven. The heating chamber features generously radiused, interior surfaces which from an integral, parabolic, reflective surface with substantial width for enhancing air flow, to increase air velocities and create evenness of heat within the heating chamber, thereby contributing to the performance of the oven.
