II. COMPONENT FUNCTION (Figure 1-4)

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 30 seconds to 12 minutes; this is the time that a product can take to pass through the oven.

B. Blower Fan

The circulation air blower drive motors (2) are located in the right side control box. The blowers force heated air through the air fingers. The MAIN / BLOWER switch must be set to “ON” or “I” for oven warmup and baking.

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

Cooling fans are located at the rear of each (left and right) control box. Cooling air is drawn into each control box and blown across the control components and circulating blower bearings and exits the oven front and rear louvers.

IMPORTANT

THE CONTROL BOX DOORS MUST BE CLOSED WHILE THE OVEN IS HOT OR HEATING IN ORDER TO KEEP THE COMPONENTS AND BEARINGS COOL.

D. Air Fingers - See Figure 1-7

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.
