Abstract
A run-through grill has at least two rolls which are mounted for rotation about horizontal axes. Each of the rolls comprises a jacket, which is heatable through a heating element arranged in the roll. A cavity is provided substantially symmetrically within the jacket, and contains the heating element. A filling of a heat-conductive material which is fluid is provided in the cavity. The filling quantity is chosen so that on the one hand an unfilled portion of the cavity remains, and on the other hand, at least sections of the heating element are continually in heat-transmitting connection with the filling. With this arrangement, the region of the jacket which borders on the unfilled cavity assumes a different temperature during passage of a cooking product to be treated than the region of the jacket in which the filling is present.
