B. Air Fingers

The PS540-Series Ovens are conveyorized ovens that employ vertical jets of hot air streaming from air fingers (Figure 1-5) to give uniform, intense heating. The vertical streams of hot air provide an exceptional heat transfer rate and generally bake faster and at lower temperatures than convection hot air or infrared heating ovens.

A PS540-Series Oven can accommodate up to four bottom air fingers and four top air fingers. Some PS540-

Series ovens used to bake pizza have four bottom fingers and two top fingers. For special product baking require- ments, a number of other styles of fingers and finger arrangements are available from the factory.

NOTE: Some customers have a predetermined finger arrangement. If you have any questions pertaining to the finger arrangement, please call the factory.
