What are the benefits of owning a conveyor oven?

Middleby Marshall Ps 350 Pizza Oven Manual
  • It insures quality and consistency of your product. Just put a pizza on the conveyor, you can then work on something else, and in a few minutes the pizza will be done. This makes the conveyor oven a good solution where there is plenty of work to be done and limited staff to do it. Additionally, it takes the worry out of food safety and reduces liability.

What belt speed and temperature should I start out with?

  • For a fresh dough regular crust (hand tossed) product, it?s good to start at a belt speed of 6 to 8 minutes and at an oven temperature of 475F to 510F. Always start with cheese pizza and perfect it! Then introduce additional toppings, checking doneness until you are satisfied. Remember ?time is doneness, temperature is color?.

Can I place product right on the belt?

  • If the crust is par-cooked and rigid, then yes! This will also decrease your belt speed since the par-cooked dough needs less time to cook when compared to fresh dough. If the crust is Fresh dough, then No as Fresh dough will just seep through and cook around the belt, which will not allow the proper removal of product once it?s cooked.

Why does my pizza look cooked but the crust is still not crispy?

  • Typically, this means the belt speed is to too fast and the temperature is too high. The product is ?searing? and not allowing the heat to penetrate the product. Slow down the belt speed and lower the temperature to assure proper baking.

How often do I need to clean my oven?

  • There are daily, weekly, and monthly cleaning requirements to ensure proper function of the oven. Refer to the owner?s manual maintenance section for more info.

How important is it that my oven is plugged into the correct voltage?

  • Extremely! Check with a qualified electrician before ordering.

Do I need to place this oven under a hood?

  • All Middleby Marshall Ovens require an exhaust hood.

PS360-series ovens feature two blower motors. A blower
wheel is fastened onto the end of the motor shaft. In
order to adjust the amount and speed of heated air that
is directed by the blower wheels, it is necessary to
change the size of the wheels and/or change the speed
Each PS360-series oven model has a specific combi-
nation of blower motor and blower wheel. Field modifi-
cations to these approved combinations are not per-
mitted unless under the specific directions of the
Middleby Technical Service Department. Any changes
to convection air delivery MUST be made using the air

mounted inside each of the end compartments of the
oven, with a pulley on the end of the motor shaft. The
oven has two blower wheels; a belt connects each motor
pulley to a pulley on the end of one of the blower wheel
shafts. The air velocity can be changed by using a
larger or smaller pulley on the motor shaft, and chang-
ing the length of the belt to match the new pulley. See
Some customers have a specific belt/pulley combina-

SECTION 2 - AIR FLOW AND HEAT TRANSFER
A.Description and Function
Air fingers direct the heated air from the blowers into
vertical jets that are directed at the top and bottom of
the conveyor belt. Each air finger configuration has
been tested to optimally cook a specific customers
product. As a rule, air finger configurations should NOT
be changed from customer specifications without di-
rect instructions from the Middleby Technical Services
Middleby uses two main types of air fingers:

rate plates, each with a series of holes, that are
relative to each other to restrict the air flow through
the holes as necessary. These fingers are no longer
in general use, but may still be found in older ov-
