DESCRIPTION
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 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 ngers.
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
compartments 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 cover-
ing 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.
