Abstract
Abstract A broiler especially for hamburger patties has an endless conveyor arranged on a frame with the horizontal upper run of the conveyor subjected to the usual supply of heat from above. A stack of initially frozen hamburger patties is arranged above the initial or entry portion of the conveyor upper run, all but the lower patty being confined. Extra heat is supplied from below to the spaced-apart metal rods of the conveyor upper run and to the lower patty lower surface so that the rods burn into the lower portion of the patty. Sufficient interengagement results so that the conveyor readily withdraws the lower patty from the stack.

A broiler with a patty-feed comprising a frame; a cover enclosure on said frame and including a top wall, side walls, a rear wall, and a front wall, said front wall having a feeding opening in the upper portion thereof, said feeding opening extending horizontally and vertically to the width and height of a stack of a plurality of hamburger patties, and said front wall having a discharging opening therein below said feeding opening; a vertical reflector wall and a vertical gauge wall extending transversely between said side walls and being substantially separated from each other to define an intermediate space, said gauge wall and a portion of said side walls defining a three-sided enclosure for and extending for more than the height of said stack of patties; an endless patty conveyor within said cover enclosure; means for supporting said conveyor on said frame with an upper run extending horizontally within said enclosure from a feed location adjacent said feeding opening, then beneath said gauge wall and said reflector wall to a discharge location spaced from said rear wall; means for advancing said upper run away from said feeding opening; a heating element on said frame above said upper run and disposed on the side of said gauge wall and said reflector wall opposite to said feeding opening; cooked patty conveyor means on said frame extending from just beneath said discharge location downwardly and forwardly toward said discharge opening; and thermal insulation occupying all of such intermediate space and lining all of one side of said three-sided patty stack enclosure.
