The multiconveyor convection oven comprises a baking chamber, at least two spaced-apart conveyors mounted transversally one over the other in the baking chamber, a heating chamber behind the baking chamber. A convection system is provided for allowing a circulation of the air from the baking chamber to the heating chamber and back to the baking chamber to cook the food. The convection system comprises air return passages providing a fluid communication between the baking chamber and the heating chamber, a blower housing extending vertically outside the heating chamber on a side thereof, at least two centrifugal blower chambers, one for each conveyor, mounted one over the other within the blower housing. Each centrifugal blower chamber has an air inlet in fluid communication with the heating chamber for drawing air from the baking chamber and an air outlet for throwing back heated air at high pressure. The convection system also includes plenum chambers and ducting means disposed within the baking chamber for conveying the heated air at high pressure exiting from the plenum and dispensing the same in the baking chamber to cook food.
