Abstract
Abstract A commercial barbeque cooker has a cooking room in which the meats to be barbequed are supported on racks. The room is heated by a remote hardwood burner which discharges hot smoke and gases into the circulating duct system of the room. The meat is subjected to the heat of the combustion gases from the hardwood burner in the range of 225 to 260*F. to barbeque the meat. Smoke from a separate smoke generator is admitted into the circulating duct system of the room as required. The circulation of the hot combustion gases is uniform and downward from the top of the room through the meat in the racks and then upwardly for recirculation.
