The purpose of the Negative Chilling cycle is to rapidly bring the fresh or cooked product core temperature to -18°C.
It is always best to pre-cool the cell before starting a Negative Chilling -18°C cycle.
Negative Chilling with saved recipe (Cookbook)
Select the Negative Chilling cycle from the main screen touching the corresponding icon.
Select the icon for the food to be chilled ("MEAT" in the example).
Touch the Cookbook icon.
Various factory set Negative Chilling
cycles are displayed, all dedicated to the selected product category ("MEAT" in the example).
Touch the corresponding name, for example, "ROAST PORK".
Launch the recipe with the START key.
If the cycle includes a needle probe, a message (Add needle probe) reminds the user to do this.
If some changes to the cycle phases were needed, press the SET key. These settings apply only to the cycle to be run (changes are not permanent and are cleared when exiting the program). Settings can only be change before starting the cycle and not when running.
Screen appearing when the cycle has started
The recipe ends at the end of the set time (if it is a time cycle) or when the set core temperature is reached (if the cycle provides for a core probe).
To stop the cycle early, touch the STOP key.
At the end of the Negative Chilling cycle, the machine automatically switches to Negative Storage mode.
Cycles that ended and normally moved on to the storage phase can be saved in My recipes.
Editing saved recipes (Cookbook) and creating a personal recipe (My recipes)
Recipes in the Cookbook section CANNOT be deleted or PERMANENTLY changed.
These settings can only be edited for the cycle to be run (changes are not permanent and are cleared when exiting the program). Settings can only be change before starting the cycle and not when running.
Alternatively, the recipe changed by the user can be saved with another name (e.g. "RABBIT ROAST WITH POTATOES”) and will be saved under My recipes.
If, before touching START, you decide to change the parameters of the cycle you want to start (“ROAST PORK” in the example), touch the SET key.
Set the desired values touching the value you wish to change: it will turn blue. Act on keys “-” and “+” to set it.
Save settings with “√” or clear the entered values with “x”.
At this point you can:
Run the new set recipe by pressing the START key, remember-
ing that the changes made will only be applied to the cycle to be run.
Save the new set recipe under a new name; later on, to use this and all other personal recipes, touch the My recipes icon. To save a recipe with a name, continue the procedure.
Save the new recipe by touching the Save key.
Enter the name of the recipe on the keypad (“ROAST PORK WITH POTATOES” in the example”), confirm with “√” or delete with “x”.
Touch the position where you wish to save the recipe: confirm the chosen position with “√” or delete with “x”.
If the selected position is already occupied by another recipe, a warning to be con- firmed appears on the display (“Overwrite the existing recipe in place 01”).
Negative Chilling with automatic or manual cycles
If, having selected a product category (for example "MEAT"), no recipe is found for the food to be chilled, you can use either automatic or manual chilling.
Select the Positive Chilling cycle from the main screen touching the
corresponding icon.
Select the icon for the food to be chilled ("MEAT" in the example).
Select the cycle to be run (it will turn blue):
- needle probe: automatic cycle, with core probe,
- small size: manual cycle, timed, chill- ing of small food
- large size: manual cycle, timed, chilling of large food
The last two do not require a needle probe but a set chilling time (editable).
Touch the SET key, to check the settings of the selected cycle.
If the settings suit your needs, run the positive chilling cycle by pressing START.
Changes will only apply to this cycle (changes are not permanent and are deleted by exiting the program).
When the fan speed is changed during chilling, the initial fan value is saved.
Screen appearing when the cycle has started
The recipe ends at the end of the set time (if it is a time cycle) or when the set core temperature is reached (if the cycle provides for a core probe). To stop the cycle early, touch the STOP key.
At the end of the Negative Chilling cycle, the machine automatically switches to Neg- ative Storage.
Cycles that ended and normally moved on to the storage phase can be saved in My recipes.
Negative Storage
During the Positive Storage phase (which automatically follows each Positive Chill- ing cycle) the cell temperature is kept at +2°C.
Fan speed can be adjusted by other storage parameters cannot be changed. Press STOP to end the cycle.
When a cycle is interrupted due to a blackout or other reasons, the green area, that indicates the storage phase, turns red.
Saving the completed Negative Chilling cycle
Cycles that ended and normally moved on to the storage phase can be saved in My recipes.
Save the finished cycle touching the Save key.
Enter the name of the recipe on the keypad (“ROAST PORK WITH POTATOES” in the example”), confirm with “√” or delete with “x”.
Touch the position where you wish to save the recipe: confirm the chosen position with “√” or delete with “x”.
If the selected position is already occupied by another recipe, a warning to be con- firmed appears on the display (“Overwrite the existing recipe in place 01”).
The recipe is saved in the memory space for Negative Chilling and for the product category (e.g. "MEAT").
All cycles saved in My recipes FROM COMPLETED CYCLES, are the repetitions of times and temperatures recorded during the operation and do not require the core needle probe (indicated by the clock symbol next to the recipe name). My recipe cycles saved from a COMPLETED CYCLE must only be used with the same type of food and size as the completed cycle.
Fish sanitation cycle - gastronomy version
Insert the probe into the food to be chilled.
- Negative chilling with chamber set to -40°C (parameter AK1) until the needle probe reaches -20°C (parameter AK2).
- Maintenance for 24 hours (parameter AK3) with chamber setpoint at -20°C (param- eter AK2).
- Negative storage with chamber setpoint at -20°C (parameter AK4).
When the temperature read by the needle probe reaches the end Negative chilling temperature, the device automatically switches to Maintenance. After the mainte- nance period, the device automatically switches to Negative storage.
ANISAKIS
Anisakiasis is a parasitic infection of the gastrointestinal tract caused by eating raw or insufficiently cooked seafood products containing Anisakis simplex larvae: if the larvae penetrate the intestinal wall, they cause a violent abdominal pain, associated with nausea and vomiting.
Should, one or two weeks after the infection, these succeed in passing into the intestines, a significant immune response can occur, with intermittent abdominal pain, nausea, diarrhoea and fever or intestinal perforation.
Ice cream softening function
This function allows softening the ice cream after getting it out of the freezer at -18°C: the softening cycle with dedicated algorithm and heat supplied by the resistances, brings the ice cream to a temperature of -12/13°C, ideal for presentation and sale, cut- ting down on time without ruining it.
To use this cycle, the needle probe needs to be inserted into the ice cream bowl: insert it deeply into the central part, preventing it from touching the sides: when the probe detects that the set temperature has been reached, it stops the cycle.
