Equipment Description

Groen Model E E ar e floor-mounted, tilti ng,
steam-j ac k eted kettles which have
thermostatically controlled, self - c ontained,
electrically - heated steam supplies and
appropriate c ontrols, mounted on a sturdy base.
Heat produced by el ec tric heating element s
boils water in a r eservoir below the jacket t o
produce steam under pr essure.

The kettle is surrounded by air-insulated
stainless steel sheathi ng. Stainl ess steel panels
enclose all of the contr ols. Three stainless
steel, tubular legs support the uni t.
EE kettles are available i n 20, 40, 60, 80 and
100 gallon capacities. Kettle bodies are welded
into one piec e. Models are all equipped with a
sanitary tangent draw-off ( pr oduc t faucet) valve
and a stainless steel strainer. This standard
draw-off is two inches in diameter, and uses a
compression di sc valve. The unit is controlled
with a thermostat, which turns el ec tric power on
or off, and sets the cooki ng temperature.
Instruments are provided to show what is
happening inside the unit:

• Water gauge glass: shows the level of water
within the steam jacket

• Pressure/v ac uum gauge: shows the steam
pressure and if t her e is air in the jacket

• Indicator lamp: Lights when the kett le is
being heated

Automatic controls within the unit:

• Contactor: Controlled by the thermostat ,
turns heating element power on or off

• Low-wat er cutoff: Turns off power to k eep
heating elements fr om ov er heating if water
loss exposes them above the water level.

• Safety valve: Releases steam if jacket
pressure gets too high

The jacket is fi lled at the factory with water that
contains rust i nhibitors. When air is removed
from the jacket, the kett le efficiently provides a
unifor m heating temperature r ange of 150
approximately 270
allows the kett le to be used for warm ing,
simmering, boi ling or brai si ng.

The inter ior of t he k ettle is pol ished to a 180
emery grit finish and the exterior is gi ven a
unifor m Number 4 finish. The unit is ASM E
shop inspected and registered with the National
Board for working pressures up to 30 PSI.

Optional equipment for the EE and A E k ettles
includes:

• Three inc h dr aw-off valve

c” perforated or solid disc strainer

•

• Basket inserts (TRI-BC)

• Water fill faucets

• Automatic water filler

• Kettl e brush kit

OM-EE

The operator controls kettle heating with t he
thermostat dial. The dial tur ns heating element
power on or off and sets the kettle oper ating
temperature.

A. To Start Kettle

1. EVERY DAY make sure the jacket water

level is between the marks on the gauge
glass. If the level is too l ow, see “Jack et
Filling and Water Treat ment” on page

11.

2. W hile the kettle is cold, check the

pressure gauge. If the gauge does not
show 20 to 30 inches of vacuum (that is,
a reading of 20 to 30 below 0), see
“Jacket Vac uum” on page 10.

Be sure that the pressure/vacuum
gauge shows at least 20 inches of
vacuum.

Operation

WARNING
OPEN THE KETTLE LID CAREFULLY TO
AVOID STEAM WHICH MAY ESCAPE.
DIRECT CONTACT COULD RESULT IN
SEVERE BURNS.

CAUTION
KEEP FLOORS IN FRONT OF THE
KETT LE WORK AREA CLEAN AND DRY.
IF SPIL LS OCCUR, CLEAN AT ONCE T O
AVOID SLIPS OR FALLS.

2. Use of Optional Basket Insert
The optional kettl e basket insert set will

assist in cooking water- boiled products
such as eggs, potatoes, v egetables, shell
fish, past a and r ice. The nylon mesh liner
must be used for pr oduc ts smaller t han the
basket mesh size, ( appr oxim ately 1/4” (6
mm). This inc ludes rice and smal l pasta
shapes.

3. Mak e sure t hat the strainer c overs the
draw-off valve outlet at the bottom of the
kettle. This keeps food sol ids from
collecting in t he dr aw-off area.

4. T ur n the thermostat dial to t he desi r ed
setting. The indicator light will confirm
that the kettle is heating. Cycling of the
light on and off shows that the k ettle is
being held at the set temperature. Once

in each cycl e contactors in the
support housing will make a clicking
sound. This is normal.

B. To Transfer Product or Empty Kettle:

1. T he k ettle is emptied by means of its
draw-off valve, by ladling pr oduc t out, or
with the optional tri - basket insert.

Tips For Use.
a) Allow f or displacement of the t hr ee

baskets and product. This may mean
only filling the kettle half way. Test
baskets and product displac ement with
the kettle OFF, and with cold water in
the kettle.
