THEORY OF OPERATION
Forza Express Technology
The Forza Express oven uses a combination of high speed air convection and infrared radiation energy
to heat and cook food faster than traditional cooking methods.
With the use of a single blower fan, air enters the cavity from the top and distributes evenly over the
product and forces down through the hokes of the bottom jet plate for even cooking.
To allow uniformed cooking, please make sure to leave the bottom jet plate inside cavity during use.
If jet plate is not installed during cooking, damage may occur to the oven.
The figure below illustrates the steps involving the technology.
1) The blower motor spins at high revolutions causing high speed air to circulate trough the top
cavity, trough the top and bottom jet plate, and back to the blower.
2) The top heater transfers thermal energy to the circulation air created by the blower motor
located in rear of unit.
3) The hot air works by creating thermal energy that heats up the product.
4) The IR element assist in maintaining the temperature inside the cook cavity and cooking the
bottom of the product. The air flowing through will also retain some heat when passes through
IR element.
5) The catalytic converter catches and burns off most of the grease and odors when the forced
air passes through it. This component is wh
at makes the oven’s use without a ventilating hood
possible.
