All Crown direct connected steam jacketed kettles pertaining to this manual are direct steam operated pressure
vessels of a double-wall stainless steel construction forming a steam chamber (jacket) enveloping the lower two
Crown direct connected steam jacketed kettles consist of a stainless steel bowl and a stainless steel jacket which
envelopes the 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
