II. COMPONENT FUNCTION

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 stainless-steel wire belt can travel in either direction at variable rates ranging from 1 minute to 10 minutes; this is the time that a product can take to pass trough 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 warm- up and baking.

C. Electric Heaters

There is one heater element mounted on the inside of the rear panel. The element is connected to an electrical control which is energized by the temperature controller.

D. Cooling Fan - See Figure 1-4

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 compartments into the oven top and exhausted out the front louvers.

E. Air Fingers and Blank Plates - See Figure 4-8, 4- 14

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 it’s holes aligned with the holes of the outer plate.

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