An efficient convection oven is described. The oven utilizes a single inlet centrifugal induced back draft fan disposed in a sidewall thereof between vertical burners and combustion chambers to constantly mix products of combustion from the combustion chambers with air from within the oven cavity and recirculate the same. The fan design of the instant invention permits air changes within the oven cavity in the range of 85 to 100 per minute and the vertical burner fan combustion chamber combination permits a dramatic increase in the rack space within the oven cavity for a given oven exterior envelope.

Convection oven with power induced back draft flow

A ventilated conveyor oven is provided. The oven uses a makeup air fan to admit air to the plenum extending across the front of the unit and across the top of the unit. Exhaust channels are provided on the sides spaced above and below the conveyor oven entrance and exit and extending across the top to an exhaust fan outlet. The exhaust channels on the top are superimposed over the air makeup plenum. Vertical exhaust plenums are provided at each of three corners, with the fourth corner mounting a control panel and an air makeup external channel thereover.
