Accu-Steam™ Installation and Owners ManialMP5004-1202 PAGE 11THEORY OF OPERATIONINTRODUCTIONThe ACCU-STEAM™ griddle is constructed and uses technology like no other griddle in theworld. The diagram below is a cross-sectional view of the griddle. The griddle cooking surfaceis the top of a chamber in which we have produced a unique environment. Welded stainless steelreinforcement studs connect the chamber top to the chamber bottom. The perimeter joints areall robotically welded to produce a vessel that is airtight, which is verified using a helium massspectrometer. The chamber is filled half full with distilled water. The remaining air is removedand 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. Athermowell for a temperature sensor to sense temperature and a thermowell for the overtempsafety 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 acanning jar. At temperatures above 212°F (100°C), the chamber operates under pressure. Locatedbetween 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 temperatureof the steam and reports this data to the thermostat, which energizes the heating elements. Thissystem maintains the griddle cooking surface temperatures to within ± 5°F (2.7°C) over theentire cooking surface and provides a near instant temperature recovery, even in the same spot onthe griddle, when turning food in place.
