Abstract This invention provides an oven to produce a desired baking effect while simultaneously providing the bread with a desirable brown coloration in both its top and bottom surfaces. A unique feature of this oven is the provision of a top radiant refractory arch wall and top flame heating to effect a desired radiance to the refractory arch surface, and also to simultaneously produce a desired radiance to a horizontally disposed radiant plate suitably disposed above the bread travelling continuously there beneath. The oven of this invention provides for substantially flash baking of relatively thin bread discs with a suitable crust formation and coloration of both its top and bottom surfaces. This oven provides also a novel method of baking relatively thin bread material. This invention accordingly provides an indirectly fired novel baking oven having novel features, to wit: a tip refractory oven surface for baking purposes supplemented by a specifically provided radiant heat-bank plate for providing a desirable brown crust in a minimum of time. The bread discs travel on a conventional metal conveyor continuously beneath the radiant plate so that a vast number of bread loaves are bakes to perfection in a minimum of time.
A baking oven for bread comprising a top radiant heat bank ceramic horizontally disposed oven wall of semi-cylindrical construction having a front portion and rear portion to form a combustion chamber; a bottom radiant heat bank plate means engaging said ceramic wall in a non-air tight relationship to provide leaked air into the combustion chamber; a metal continuous conveyor, having a top portion separated from a bottom portion, disposed beneath said radiant plate and adapted to convey bread loaves in its top portion in suitable space relationship to said radiant heat plate, a burner disposed in the top of said ceramic wall; inlet duct opening means engaging said ceramic combustion chamber; an elongated heat chamber means disposed between the said top and the said bottom portions of said conveyor; exit duct means engaging said elongated heat chamber at its front portion for removal of said combustion gases and leaked air to the atmosphere; and exhaust fan means for producing a vacuum to produce leaked atmospheric air beneath the ceramic wall and into the combustion chamber whereby combustion gases are prevented from entering the bread baking area of the oven.
