2.0 INTRODUCTION

DESCRIPTION

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 sufficient not only to immerse and thereby protect replaceable electric
heating elements, but also provide the steam 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.

All tilting kettles are intended to be permanently floor mounted on legs with adjustable
flanged feet.

A sealed stainless steel tilt mechanism permits the kettle to tilt forward a full 90E for
complete emptying. The tilting mechanism is self locking for positive stop action.

MIXER FEATURES

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 140E out of the way for tilting the kettle(s).

CAPACITIES

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.

2.0 INTRODUCTION (Continued)

FUNCTIONING MODE

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.

When the Power Switch is turned ON and the Temperature Control (Thermostat) Knob
dialed, the TEMPERATURE 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 to heating
the elements. The TEMPERATURE pilot light will then extinguish. When the temperature
of the water in the jacket drops slightly, the cycle will repeat itself thus making it possible to
maintain any selected precise cooking mode temperature.

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
jacket. The Safety Probe sensing depletion of the water level in the kettle jacket will not
only activate the LOW WATER level indicator pilot light, but also signal the Liquid Level
Control to switch off power and de-energize the circuit to the heating elements (preventing
element burn outs) until the water level is adequately replenished.

FUNCTIONING MODE (Continued)

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 140E 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.

4.0 OPERATION INSTRUCTIONS (Continued)

OPERATION OF MIXER UNIT

Power to operate the mixer unit is controlled by the “Main Power” switch located on the left

side of the control panel. Ensure that mixer “speed” control is set to the “stop” position.
Place switch in the “ON” position. Set the mixer switch, located beside the main power

switch, to “ON” position. Note that the agitators should not be turning. The speed control
has four basic settings which are: stop, slow, medium and fast. Set the speed control to the
slow position and observe that the agitators begin to turn.

CAUTION: Never place hands inside kettle when agitators are
in motion.

Increasing the speed setting on the control will increase the speed at which the agitators turn.

NOTE: Always start agitators at the slow speed and then gradually increase
to the desired speed to avoid splashing or “throwing” the product over edge
of kettle.

TO RAISE MIXER BRIDGE

To tilt kettle for emptying or to clean agitators, the mixer bridge will tilt hydraulically upward
and manually swing clear of the kettle. To do this, first turn speed control to “STOP” and then
turn mixer switch to “OFF”.

NOTE: Mixer agitator arms must be stopped at 90 degrees to the
mixer bridge before raising the bridge. If the agitator arms do not
stop in this position when speed selector is set to stop, then “jog”
the selector on and off to achieve this position.

Push the “TILT” switch to the “RAISE” position and hold. Bridge will raise to maximum

height. Bridge will stop at any position if the tilt switch is released and will remain in that
position until switch is pushed to either raise or lower. When the bridge is fully raised it
can be manually turned to the side to be clear of the kettle.

4.0 OPERATION INSTRUCTIONS (Continued)

NOTE: The bridge is equipped with a safety switch which prevents turning
of the agitators, regardless of the mixer switch, or speed control settings.
Agitators will not engage unless the bridge is lowered so that the guide pin
rests fully in the guide pin bracket on the side of the kettle.

OPERATION OF MIXER UNIT

REMOVAL OF AGITATORS

For ease of cleaning, the agitators are removable without tools. To remove, raise bridge
as described above and swing clear of kettle. Grasp shaft of large agitator, push up and
turn to disengage lock pin. Pull straight down on agitator. Remove the small agitator in
the same manner. Soak and wash agitators in warm, soapy water. Never use abrasive
cleansers or scouring pads on the stainless steel surfaces as this will damage the finish
of the stainless steel.

If it is necessary to remove the scraper blades from the large agitator for cleaning purposes,
do so by removing the pin at the end of the mounting shaft and then slide the scraper blades
off of the shaft.

To clean the exterior stainless steel panels of your unit, use a damp soft cloth or soft cloth
and stainless steel cleaner. Never use abrasive cleansers or scouring pads on the
stainless steel surfaces as this will damage the finish of the stainless steel.
