Description of the unit
4.3 Operating and cooking modes
4.3.1 Operating modes
Manual cooking
In the Manual cooking mode, individual cooking programs and
equipment functions can be activated directly. The various cooking
modes and equipment functions can be modified individually.
Automatic cooking
In the Automatic cooking mode, saved cooking programs can be
activated and modified if necessary.
4.3.2 Types of cooking
Steaming
Steaming is a cooking mode, in which the food to be cooked is
cooked gently by means of steam in a temperature range of 30 °C to
130 °C.
Combisteaming
Combisteaming is a cooking mode, in which large roasts, casseroles
and baked goods can be cooked in a temperature range of 30 °C to
250 °C.
10014471-0ABBE-A
Hot air
Hot air is a cooking mode, in which the food to be cooked is cooked
without additional moisture in a temperature range of 30 °C to 250 °C.
17Operating instructions
Description of the unit
Regeneration
Regeneration is a cooking mode, in which the food being cooked can
be kept warm and prepared in a temperature range of 30 °C to 155
°C.
4.3.3 Expanded cooking functions
Expanded cooking functions can be used to modify individual cooking
steps for the particular food being cooked.
The following expanded cooking functions are available:
Manual humidification Manual humidification allows the cooking zone humidity to be
increased during operation.
Start time delay
When using the start time delay, temperatures that promote the
growth of harmful microorganisms on the food being cooked can
occur in the cooking zone. Observe food processing regulations.
The start time delay can be used to set a waiting period until the
program starts.
In this way, bottlenecks in production and preparation can be
avoided.
The prepared food to be cooked can be loaded into the unit and the
desired cooking program selected.
Heat (Ready2Cook)
The function can be selected when starting the cooking
program.
For many cooking programs such as baking, for instance, the correct
starting temperature is important.
The expanded heating function can be used to warm the cooking
zone to the correct starting temperature.
4.3.4 Core temperature measurement
When using core temperature measurement, the temperature inside
the food being cooked is measured by means of a core temperature
sensor.
As soon as the target core temperature is reached, the cooking
process is ended automatically or, in the case of a multi-step cooking
program, the next cooking step starts.
The use of core temperature measurement offers the following
benefits:
• Reduced energy and water consumption
• No overcooking
• Less weight lost by the food being cooked
• High HACCP safety
