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 roller grill assembly includes a roller grill housing and a plurality of rollers disposed in an array and rotatably supported by the housing, each roller having an external heating surface, a first opening at a first end thereof and a second opening at a second end thereof. The roller grill assembly also desirably includes heating elements provided in the rollers for heating the external heating surfaces, and a first insulating end cap secured in the first opening of each roller and a second insulating end cap secured in the second opening of each roller for minimizing heat loss through the ends of the rollers.
