Abstract: A cooking apparatus for cooking particulate foods comprising an elongated source of radiant heat, a container for retaining the food adjacent the source of heat, a helical device within the container for moving the food through the container and along the source of heat, the helical device having a lesser pitch at the feed end than at the discharge end so that the food is moved more slowly near the feed end and more quickly near the discharge end, means for causing the food to cascade as it passes through the container, the apparatus being arranged so that food which is introduced into one end of the container is advanced therealong at a progressively increasing rate and cascaded therein in order to produce even cooking of the food as it passes through the apparatus.
