The
Duromatic pressure cookers by Kuhn Rikon represent a second generation
of pressure cookers. These pressure cookers are built with safety features
that prevent the problems sometimes seen with earlier cookers.
First,
the automatic lid-locking device of the Duromatic pressure cookers insures
that no pressure can be built up until the lid is on properly. It also
insures that the lid cannot be removed or come off until all of the pressure
has been released.
The
Duromatic cookers provide the ultimate in protection against excess pressure.
The first indication that too much pressure has built up inside the cooker
is the audible hiss of the valve as excess pressure is released through
the valve (which is normally quiet.) When the user hears this, the heat
should be turned down. As long as the valve is not clogged, it will relieve
any over-pressurization by allowing steam to escape through the radial
escape holes located on the valve stem.
Other
safety releases will come into effect only if the central valve becomes
clogged. If that occurs, excess pressure can also escape through the safety
holes in the rim of the lid.
Additionally,
another spring-loaded safety valve is set to release steam in the case
of a clogged main valve due to overfilling or too-high heat. This valve
is not a blow-plug like some old domestic cookers had, but a highly accurate
spring-loaded valve which will open at a preset internal pressure and release
steam safely and effectively.
Finally,
at higher pressure, the gasket is forced out through the six bayonet flanges
in the lid, and excess steam escapes in a downward direction. |
