<p>The present invention is therefore directed to a method and apparatus for warming a stack of cheese slices. In accordance with the invention, the stack of cheese slices (20) is positioned between and in juxtaposition with opposing generally planar electrodes (14, 16), each of the electrodes having a surface area generally coextensive with that of the cheese stack. Next, a conductive material (22) is interposed between each electrode and the cheese stack to reduce contact resistance. Once properly assembled, an electric current is passed between the electrodes, through both the conductive material and the cheese, thus warming the individual cheese slices through ohmic heating. In accordance with one embodiment of the invention, the conductive material is a moistened paper sheet.</p> |
