The TurboChef NGC (Tornado
three independent heat transfer mechanisms to
rapidly cook food.
The systems are as follows:
Convection
Infrared energy
Microwave energy
By combining these mechanisms along with the
ability to control each mechanism independently,
the NGC (Tornado) oven is able to reduce the cook
time of most foods by 70-90 percent.
Figure 5 below represents the oven's different sys-
tems and the critical components of each system.
