Introduction

Oven Description and Components
Cooking in a conveyor oven differs from cooking
in a conventional deck or range oven since heated
air is constantly recirculated over the product by
a fan in an enclosed chamber. The jets of moving
air continually strip away the layer of cool air sur-
rounding the product, quickly allowing the heat to
penetrate. The result is a high quality product,
cooked at a lower temperature in a shorter amount
of time.
This Blodgett conveyor oven represents the latest
advancement in energy efficiency, reliability, and
ease of operation. Heat normally lost, is recirculated
within the cooking chamber resulting in substantial
reductions in energy consumption, a cooler kitchen
environment and enhanced oven performance.

OVEN COMPONENTS

Conveyor Belt --- stainless steel chain link (con-
veyor) belt that carries product through the oven.
Conveyor Belt Master Links --- allow easy re-
moval of the conveyor belt for more thorough
maintenance and cleaning. Identified by locating
double spaces between regular links on the belt.
Conveyor Rack Assembly (drive & idle sides) ---
located on both ends of the oven deck. The drive
side has a drive shaft and sprocket which slide into
the electrical box. The conveyor can be removed
as one piece without removing the belt.
Optional Folding Conveyor Rack Assembly ---
conveyor belt and rack assembly that carries
product through the oven. This rack folds for ease
of removal in small spaces. The conveyor can be
removed as one piece without removing the belt.
Conveyor Belt Tensioners --- maintain tension on
the conveyor belt.
Electrical Box --- contains electrical components,
wiring, cooling fans, drive motor, drive chain, and
combustion blower/burner assembly (gas ovens
only) or electric elements (electric ovens only).
Drive Motor --- provides power to move the con-
veyor belt. The operator and control system deter-
mine the speed. Belt travel direction (left to right or
right to left) is factory set and is easily changed.
Drive Chain --- connects the drive motor sprocket
to the conveyor drive shaft sprocket.

baking chamber on the belt.
Nozzles --- distribute heated air from the bottom
of the baking chamber. Located inside the oven,
under the conveyor belt.
Nozzle Support Bracket --- removable bar that lo-
cates the front end of the nozzles. Located just in-
side the oven's front door beneath the nozzles.
Air Flow Plate --- distributes heated air from the
top of the baking chamber.
Conveyor Support Angle Bars --- provide sup-
port for conveyor rack assembly.
Crumb Pans --- catch crumbs from products on
the conveyor. Located under conveyor belt at both
ends of the baking chamber.
Operator Controls --- used to control oven tem-
perature, belt speed and other functions.
Ignition Control Reset Button (gas ovens only) ---
resets ignition control/gas burner after a lockout. Lo-
cated on the lower panel of the control box.
Emergency Stop Button --- FOR EMERGENCY
USE ONLY (damage may occur)! Press the red palm
switch located next to the operator control to shut
down the oven and stop the conveyor.
