DESCRIPTION

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.

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.

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.

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.

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.
