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.
STEAM
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

Steam long-grain rice using
approximately 1-part rice to
approximately 1-1/2-parts water
or seasoned liquid.
Steam durum wheat noodles in

noodles to 5-parts cold water.
QUICK STEAMING

for hearty, root-type vegetables
such as potatoes, legumes,

Quicksteamingprovides

Set the steam cooking
temperature between 221°F

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 Key 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

with the Combination mode; therefore, the operator may want to consider using the

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 Key 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.
