Introduction
Direct Steam Kettles Mounted on Electric Boiler Cabinet Base
Introduction - Direct Steam Kettles
General
Direct steam tilting kettle(s) mounted on a cabinet base, housing an ASME Code designed electric steam boiler approved
as a steam boiler restricted to operation at pressure not to exceed 15 psi. Hot and cold water fill faucet, 5" (152 mm) deep
sink with drain and splash guard(s). All models are suffixed with either -6, -10 or -12 to indicate the capacity of the kettle(s)
in US gallons. The electric boiler may be rated at 24 kW, 36 kW, 42 kW or 48 kW. Operational on 208V, 220V, 240V, 380V,
415V or 480V and have optional CSD1 controls.
Functioning Mode
Direct connected steam jacketed kettles consist of a stainless steel bowl and a stainless steel jacket which envelopes two
thirds of the lower surface of the bowl thus forming a sealed pressure vessel (chamber) into which steam is introduced by
means of a manual control valve.
The kettle bowl is the container for the food product which ideally should be of a liquid or semi-liquid consistency to
achieve complete contact with the bowl surface and thus fully absorb the heat transmitted through that surface.
The temperatures required for the cooking process to function adequately must be greater than the boiling point of
the liquid food product. Further, the greater the steam pressure used, the higher the temperature and consequently
the quicker the cooking process. For example, steam pressurized at 30 p.s.i. attains a temperature of 274 degrees
Fahrenheit (135 degrees Celsius).
In the initial stages of the cooking process when the steam comes in contact with the cold kettle bowl surface it condenses
and forms considerable amounts of water. A thermostatic steam trap has been plumbed to the exit end of the kettle
jacket. This trap is a mechanical device that closes on high temperatures and opens when the temperature drops thus
allowing the water formed from condensate to exhaust but retain steam under pressure.
