Cooking with function “
∆
T” (DELTA-T)
Set in sequence the
“time”
parameter (turn knob “1”), the
“core temperature”
parameter
(key
/green LED on
/
turn knob “2”) for the
intended step (key
), parameter “
∆
T”
(key
/green LED on “
∆
T”/turn knob “2”) and, if desired, the
“humidity/steam”
(parameter
(turn knob “3”/blue LED bar active) for each of the intended steps (key
). Start the
cooking cycle by pressing the key
.
This function makes it possible to maintain constant, throughout the cooking step, the
difference (
∆
T) between the temperature inside the food (temperature detected by the needle-
shaped thermal probe) and the temperature inside the cooking chamber. This means that the
value of the temperature in the cooking chamber becomes the sum of the temperature inside
the food and a fixed temperature value “
∆
T” set by the user (see graph).
The Delta-T temperature is obtained from the
difference between the values of the temperature
inside the food and the temperature in cooking
chamber
In practical terms, there is a slow increase of the temperature in cooking chamber, with a
constant difference with respect to the internal food temperature which, exactly because of
that, undergoes a prolonged and delicate cooking process (in the case of meat, proteins are
protected since surface tensions caused by excessively quick crust formation are avoided).
After selecting the cooking temperature for the inside of the food (“core” temperature) and
setting the value (knob “2”), press key
again, in order to select function “
∆
T” (the
∆
T LED
switches on) and be able to set (knob “2”) the desired temperature value (experience suggests
this value should be between 30°C and 70°C).
Also for cooking with function “
∆
T”, the method to use the needle-shaped thermal probe is as
described in paragraph “cooking with “core temperature” function.
Please note
If the cooking cycle is not controlled by the core probe and has been divided into one or more timed steps, the
oven automatically switches off when the time set in the individual step or overall in the various steps has elapsed.
If an “inF” (“infinite”) cooking time has been set the oven continues working until the operator switches it off by
pressing the key
.If the cooking cycle is controlled by the core probe and has been divided into one or more
steps (even timed), when the temperature set with the probe is reached it moves to the next step; if on the other
hand one step only has been opted for (even timed), or an “inF” time, the cycle ends and the oven switches off
automatically, regardless of the time set for the step.
