Hood system for conveyorized cooking oven

Abstract From the Canadian patent

A kitchen exhaust hood covers the top of an oven and food conveyors which extend on both sides of the oven. Plates in the hood cooperate with the walls of the hood to provide slots at the hood front and sides to accelerate the air under the plates adjacent the slots and provide high velocity exhaust air flow upward in the hood at the front and sides of the hood to capture heat and fumes. The plates are located slightly above the lower edge of the hood, to minimize induction of room air horizontally into the hood under the edge, and assure collection of air that has been associated with the oven and has accumulated heat or collected contaminants. Air flow guides at ends of a conveyor direct …
