The default/memo setting allows the operator to choose
between a display showing the factory set defaults for
time and temperature or the last operator set values for
time and temperature in each cooking mode. This
adjustment function also allows the operator to change
the defaults from those set at the factory to settings that
better meet the needs of the individual operation.
Cooking product with operator set defaults for time and
temperature can help reduce operator error. Cooking
with the oven in the memo setting is particularly useful
when several batches are cooked in succession. The
memo setting eliminates the necessity to set time and
temperature for each batch.

This mode will steam a full or partial load of a single product, or multiple products
without transfer of flavors. When steaming multiple products, however, individual
product cooking times must be taken into consideration. The non-pressurized
atmosphere of the Combitherm also provides the ability to open the door during the
steam mode in order to monitor products more closely throughout the steaming process.
STEA
Perforated, 2-1/2" deep pans
(65mm) are particularly suitable
for use in this program mode.
These pans will provide a shorter
cooking time and will prevent
product over-cooking at the
bottom of the pan.
Separate ice-encased vegetables
before steaming to assure more
even cooking.
A variety of products can be
steamed at the same time but
attention must be paid to the
different cooking times required
for each food product.
Butter and season vegetables
after steaming.
Steam long-grain rice using
approximately 1-part rice to
approximately 1-1/2-parts water
or seasoned liquid.
Steam durum wheat noodles in
unperforated pans using 1-part
noodles to 5-parts cold water.
QUICK STEA ING
Quick steaming is suitable
for hearty, root-type vegetables
such as potatoes, legumes,
and cabbage.
Quick steaming provides a
cooking time which is
approximately 10-percent shorter
than the regular steam mode
temperature of 212°F (100°C).
Set the steam cooking
temperature between 221°F
(105°C) and 230°F (110°C) for
small loads and between 230°F
(110°C) and 248°F (120°C) for
full loads.
LOW TE P STEA
The low temperature steam mode
will function whenever the oven
compartment temperature is
below 212°F (100°C).
Proof yeast dough at a
temperature setting of 90°F to
110°F (32°C to 43°C).
It will take longer to steam
products using the low
temperature steam mode.
Steaming sausages in low
temperature steam prevents
cracked or peeling skins.
Use low temperature steam for
delicate foods such as shrimp,
fish, seafood, and crème caramel.
For best results, low temperature
steam all delicate food items at a
temperature of 210°F (99°C)
or below.

The Combination mode will prove to be the most versatile and widely used mode
the Combitherm oven has to offer. It will produce the best possible results on the
widest variety of products — all within the shortest period of time. The unique control
function of this mode enables the operator to roast or bake with a combination of
steam and convection heat. In addition to shorter cooking times, this combination of
steam and heat offers less product shrinkage and more moisture retention than obtained
in a standard convection oven.

Due to the automatic steam adjustment, the
door can be opened at any time during a
cooking operation. Be certain to observe the
safety warning when opening the oven door.
The Combination mode is particularly efficient
when used for baking, broiling, grilling, stewing,
braising, and roasting.
When using the Combination mode, cooking
temperatures can be reduced 10- to 20-percent
below the temperatures used for conventional
cooking methods.
Cooking time will be reduced approximately
40-percent when cooking at the same temperature
used for convection oven cooking and up to 50- to
60-percent less time when cooking at the same
temperature used for a conventional oven.
Food browning in the Combitherm begins
at a cooking temperature of approximately
248°F (120°C).
A higher cooking temperature results in heavier
browning but also results in greater product
weight loss. To achieve additional browning use
the Moisture Vent ey or set Gold-n-Brown into
the product procedure. Gold-n-Brown is
particularly useful for adding color to high moisture
products such as chicken and other poultry items
or for additional browning of full loads and other
moist products.
The Combination mode provides even browning
without the necessity to turn the pans.
For more even cooking, do not cook in pans
deeper than 4-inches (100mm).
The Combination mode injects the optimum amount of steam
automatically. There is no need to select moisture levels. Foods do not
dry out. Flavors are retained with no transfer of flavors when mixing
product loads.

The Convection mode operates with hot circulated air within a temperature range
of 86° to 482°F (30° to 250°C). For many applications, better results may be
achieved with the Combination mode; therefore, the operator may want to consider
using the Convection mode on a more limited basis.

The Convection mode works best with foods
containing little moisture or for very moist food
which require a dryer finished product.
For baking, preheat the Combitherm at a
temperature of 36°F to 54°F (20°C to 30°C) above
the baking temperature required. Once preheated,
reset the temperature as required.
A higher cooking temperature results in heavier
browning but also results in greater product weight
loss. To achieve additional browning use the
Moisture Vent ey or set the Browning Feature
into the product procedure.
To prevent the surface of food from excessive
drying, the fan will not engage if the internal
oven temperature is above 212°F (100°C)
and the set oven temperature is below
212°F (100°C).
The Convection Mode can be used to roast or bake products needing very
short cooking times or for high moisture products such as muffins, cakes,
and cookies, or for browning the surface of the product.
