PAGE 6 OF 40
Electric Self Generating Single And Twin Steam Mixer Kettles
All electrically powered kettles described and referred to in this manual are pressure vessels of a double-wall construction
forming a sealed jacket (chamber) enveloping the lower two thirds of the kettle bowl surface.
The kettle bowl is the container for the food product which ideally should be a liquid or semi-liquid consistency to achieve
complete contact with the bowl surface. Food products will fully absorb the heat transmitted through that surface from the
pressurized steam generated in the kettle jacket.
The jacket is intended to function as a self contained sealed chamber with a permanent solution of water and antifreeze
source during the steam generating process.
The heating elements are thermostatically controlled to provide precise temperatures throughout the range from slow
simmer to rolling boil.
A sealed stainless steel tilt mechanism permits the kettle to tilt forward a full 90° for complete emptying. The tilting
mechanism is self locking for positive stop action.
The mixer is a variable speed unit powered by a 5 hp electric motor driving a hydraulic pump. Two heavy duty
hydraulic motors drive the primary scraper/agitator and secondary high speed mixer. Both are removable without
tools for cleaning. They are housed in a stainless steel bridge that is power tilted and swings 140° out of the way
for tilting the kettle(s).
All models are suffixed with either -40, -60, -80 or -100 to indicate the capacity of that kettle in US gallons.
Models with the suffix -2 indicate a twin model. Thus a unit with suffix -40-2 has two 40 gallon kettles, one on
each side of the mixer console. An ELTM-40 indicates a single 40 gallon kettle two thirds jacketed electrically
powered steam kettle.
All electrically powered self steam generating kettles consist of a jacket containing a permanent solution of water
and antifreeze sufficient to completely immerse and protect replaceable electric heating elements.
To minimize tampering, the Safety Valve is plumbed toward the rear of the kettle jacket. Should any component
malfunction and cause the pressure in the jacket to reach the rated pressure of the kettle, this protective device
will open automatically and release excessive pressurized steam.
pilot light will ignite and contactors will close to allow power to the elements. Steam generation will commence
and continue until the preselected temperature is reached, at which point the contactors open, cutting off power
in the jacket drops slightly, the cycle will repeat itself thus making it possible to maintain any selected precise
cooking mode temperature.
I
INSTALLATION & OPERATION MANUAL 10041 REV 5 (10/22) PAGE 7 OF40
Electric Self Generating Single And Twin Steam Mixer Kettles
The temperature required for the cooking process to function adequately must be greater than the boiling point
of the liquid food product. Further, the higher the temperature, the greater the steam pressure attained in the
jacket and consequently the quicker the cooking process. For example, steam pressurized at 30 p.s.i. attains a
temperature of 274º Fahrenheit.
Since air is an unsuitable media through which heat may be transferred, it has been removed from the kettle jacket
during testing at the factory. The Pressure Gauge should indicate vacuum in the jacket in green zone on the gauge
(approximately 20 - 25 inches Hg) when the kettle is cold or has been inoperative for some time. The kettle jacket
is intended to function at all times as a completely sealed self-contained chamber and it is especially advisable not
to trip the safety relief valve during inoperative periods since this will break the vacuum seal and allow air to enter
the kettle jacket.
The Temperature Controls (thermostats) used in these kettles have been calibrated to prevent the heating
elements from generating steam pressure that would exceed the rated working pressure of the kettle. In the
unlikely event that the Temperature Control fails and the heating elements remain energized, the Safety Valve will
blow and release the excessive pressure and steam from the jacket, consequently lowering the water level in the
circuit to the heating elements (preventing element burn outs) until the water level is adequately replenished.
The mixer is a variable speed unit powered by a 5 hp electric motor driving a hydraulic pump. Two heavy duty
hydraulic motors drive the primary scraper/agitator and secondary high speed mixer. Both are removable without
tools for cleaning. They are housed in a stainless steel bridge that is power tilt and swings 140° out of the way
for tilting the kettles(s). Once the bridge has been lifted the agitators cannot be operated as a safety switch is
activated. Bridge may now be moved out of the way or if a twin mixer, moved to the other kettle. The speed control
is located on the front panel and may be set to the desired speed by turning. The maximum speed will not exceed
54 RPM on the smallest kettle and 40 RPM on the largest.

TO REMOVE HEAT TINT: Darkened areas sometimes appear on stainless steel surfaces where the area has been subjected to
excessive heat. These darkened areas are caused by thickening of the protective surface of the stainless steel and is not harmful.
Heat tint can normally be removed by the foregoing, but tint which does not respond to this procedure calls for a vigorous scouring
