Abstract: An apparatus and method for conditioning conveyor chains in commercial ovens of the type having a continuous conveyor chain supported in a track for transporting bakery products through the oven. A portion of the conveyor chain and supporting track transits outside the heated baking area of the oven and an automatic chain lubricator is positioned along the portion of the track transiting outside the baking area of the oven. A fan for creating a flow of cooling air and at least one air duct are located outside the baking area. The duct receives one end cooling air from the fan and directs the cooling air on to the conveyor chain along the portion thereof located outside the heated baking area of the oven and upstream from the lubricator. Also, an air knife is disposed upstream of the lubricator and directed onto the chain to remove undesired debris, etc., therefrom.

Abstract: An apparatus for baking a dough-type product includes an oven having an enclosure, a product supporting conveyor in the enclosure, burners positioned to heat the product, and an integrally associated emissions control device for controlling emissions emanating from the product while baking. A recirculating system for controllably directing air from the oven to and from the emissions control device is integrated into or with the oven, and preferably positioned in the oven enclosure.
