DESCRIPTION

A. Conveyor Motor and Conveyor Belt

The conveyor belt is driven by a variable-speed electric motor (Figure 1-5) operating through a gear reducer. The motor speed is controlled by a digital control. The stain- less-steel wire belt can travel in either direction at variable rates ranging from 3 minutes to 30 minutes; this is the time that a product can take to pass through the oven.

B. Blower Fan

The blower fans are located at the rear of the oven. These blowers force heated air through the air fingers. The BLOWER switch must be set to “ON” or “I” for oven warmup and baking.

C. Gas Burner

The gas burner is located inside the rear panel and is controlled by the temperature controller.

D. Cooling Fan — See Figure 1-5 and Figure 1-6

The cooling fan is located in the back of the oven. The cooling fan draws air through its grille, blowing it through the blower motor compartment and the control compart- ments into the oven top and exhausted out the front louvers.

E. Air Fingers and Blank Plates - See Figure 1-7

E1. Air Fingers

An Air Finger Assembly is made up of three parts:

1.Outer Plate - The Outer Plate is the removable covering with tapered holes, which direct the air stream onto the product being baked.

2.Inner Plate -The perforated Inner Plate is vital in forming the unique air jets. It must be assembled into the manifold with its holes aligned with the holes of the outer plate.

3.Manifold - The Manifold is the assembly which slides on tracks into the oven plenum.
