THEORY OF OPERATION
INTRODUCTION
The ACCU-STEAM™ griddle is constructed and uses technology like no other griddle in the
world. The diagram below is a cross-sectional view of the griddle. The griddle cooking surface
is the top of a chamber in which we have produced a unique environment. Welded stainless steel
reinforcement studs connect the chamber top to the chamber bottom. The perimeter joints are
all robotically welded to produce a vessel that is airtight, which is verified using a helium mass
spectrometer. The chamber is filled half full with distilled water. The remaining air is removed
and the chamber is welded shut. At this point, the chamber becomes a hermetically sealed vessel,
never to be opened again. The griddle steam chamber requires no water or maintenance. A
thermowell for a temperature sensor to sense temperature and a thermowell for the overtemp
safety shutdown system are also welded into the griddle steam chamber.
At temperatures below 212°F (100°C), the chamber is actually in a vacuum, similar to that of a
canning jar. At temperatures above 212°F (100°C), the chamber operates under pressure. Located
between the water and the bottom of the cooking surface is the best heat transfer medium –
steam, the most effective way to transfer heat. The temperature sensor senses the temperature
of the steam and reports this data to the thermostat, which energizes the heating elements. This
system maintains the griddle cooking surface temperatures to within ± 5°F (2.7°C) over the
entire cooking surface and provides a near instant temperature recovery, even in the same spot on
the griddle, when turning food in place.
