3.2 Features
3.2.1 Operating modes
Overview of the operating modes
•Manual cooking: myCooking
•Automatic cooking: autoChef
Manual cooking (myCooking)
In the Manual cooking mode, individual cooking processes and
equipment functions can be actuated directly. The various cooking
modes can be adapted individually. All cooking modes, equipment
functions and information can be compiled and stored as cooking
processes.
Automatic cooking (autoChef)
In the Automatic cooking mode, saved cooking processes can be
performed and adjusted if necessary.
3.2.2 Types of cooking
Overview of the cooking modes
•ReadyXpress high-speed cooking (optional)
•Cooking
•Frying
•Soft Cooking
•Deep frying (optional)
•Regenerate
•Delta-T Cooking
•FlexiZone frying
•FlexiZone cooking
•SmartBoiling
•Sous-vide cooking (optional)
High-speed cooking ReadyXpress
In the High-speed cooking mode, water is poured into the pan whilst
taking into account the minimum fill quantity. This water evaporates
and creates positive pressure in the pan.
The higher temperatures shorten the cooking time and reduce the
amount of energy required.
The cooking level and pressure release can be set according to the
robustness of the food being cooked.
10000008612ABEBEA

Description of the unit
16 Operating instructions
Cooking
Cooking mode enables food to be cooked at various boiling strengths
in a temperature range of 90 °C to 100 °C. The food is heated to
boiling temperature at maximum output, and it then continues to be
cooked with the selected boiling strength.
Frying
Frying mode enables food to be fried at various output levels in a
temperature range of 100 °C to 275 °C.
Soft cooking
Soft cooking mode enables food to be heated and brought to the boil
slowly in a temperature range of 30 °C to 100 °C. The heating output
is limited depending on the output level.
Deep-frying
Deep-frying mode enables food to be deep-fried in hot fat in a
temperature range of 140 °C to 180 °C.
The pan is divided into four different zones. Each zone can be
operated with its own cooking time. The cooking temperature is the
same for all zones.
Regenerating
Regenerating mode enables food with different levels of robustness
to be kept warm and prepared in a temperature range of 50 °C to 100
°C.
Delta-T cooking
The cooking and frying preparation styles are both available in the
Delta-T cooking mode.
Delta-T cooking is a cooking mode where the cooking temperature
depends on the core temperature of the food being cooked.
The cooking temperature is always higher than the current core
temperature by the set value (Delta-T value, cooking temperature
difference). The resulting cooking time is longer than with other
cooking modes.
Delta-T cooking is especially well-suited for gentle cooking. The food
being cooked remains tender and juicy with little weight loss.
FlexiZone frying
The FlexiZone frying mode enables food to be fried in several zones.
The frying surface is divided into up to three different zones.
Each zone can be operated with its own output and cooking time in a
temperature range of 60 °C to 250 °C.
10000008612ABEBEA

Description of the unit
17Operating instructions
FlexiZone cooking
FlexiZone cooking mode enables food to be cooked in a temperature
range of 90 °C to 100 °C. The pan is divided into four different zones.
Each zone can be operated with its own cooking time. The output and
cooking temperature are the same for all zones.
SmartBoiling
SmartBoiling cooking mode enables water to be brought to the boil
with energy saving. The set amount of water is introduced
automatically, brought to the boil with the lid closed and then held at
temperature with low energy consumption. When the lid is opened,
water is available with the set boiling strength for further use.
Sous-vide cooking
Sous-vide cooking mode enables food to be cooked with a special
vacuum cooking process. This requires an external sous-vide core
temperature sensor as special equipment.
3.2.3 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
process, 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
The following core temperature sensors are available:
•4-point core temperature sensor
and
•external sous-vide core temperature sensor (optional)
3.2.4 USB port
The unit is equipped with a USB port (USB 2.0).
A USB flash drive can be used to export and import cooking
processes and images.
HACCP logs can be exported to a USB flash drive and archived on
an external computer as necessary.
10000008612ABEBEA

Description of the unit
18 Operating instructions
3.2.5 HACCP logging
All cooking processes performed are recorded in the HACCP log.
The data are exported via the USB port.
3.2.6 SpaceClean automatic cleaning (optional)
With automatic cleaning, the pan cleaning process is fully automated.
The entire pan is sprayed down with high-pressure water. There is no
need to use an additional cleaning agent.
3.3 Application
