7 BLAST CHILLING CYCLES
7.1 - General operating principles
Pre-cooling of the machine should always be performed
upon initial running of a blast chilling or deep freezing
operation. This optimises the subsequent work cycle,
reducing the time.
Blast chillers are refrigeration systems that work with a twophase cycle:
• Chilling phase (limited duration)
• Storage phase (unlimited period)
The chilling phase starts upon pressing of the “Start/Stop”
button (22) and continues until the end of the chilling
phase that is used to achieve the time set (Time chilling) or
for reaching of the product temperature set (Temperature
chilling); changing to the unlimited duration storage cycle
takes place automatically (except for the the HARD+HARD
negative chilling cycle). It is possible to stop the chilling
or storage at any time by pressing the “Start/Stop” button
(22).
Chilling time
During this type of chilling, the display (18) shows the cell
probe temperature while the other display (19) shows the
time remaining at the end of the chilling phase. The Time
chilling LED (6) is lit as is the time symbol (20).
Temperature chilling
If Temperature chilling is selected, at the start of a cycle a
check is performed of the correct insertion of the product
probe (if enabled). If the test provides a negative result
an alert appears on the display “SONDA NON INSERITA PROBE NOT INSERT” and the beeper sounds for 60 seconds
(parameter c9); that symbol disappears when the beeper
is silenced by pressing the button (7). If instead the button
is pressed again (5) switching to Temperature cycle, the
cycle continues based on the data read by the product
probe. If nothing is pressed, the temperature cycle
automatically switches into a Time cycle for the remaining
duration of the countdown.
During this type of chilling, a display (18) will show the
temperature of the probe (the highest value of the two)
and the other (19) will show a countdown. The countdown
only starts when the insert temperature is less than 149°F
(65°C). The temperature chilling LED (4) is on as is the
probe insert symbol (17).
Chilling and strorage status symbols
During chilling the LED that lights the sybol will be lit and
flashing. Upon completion of chilling, this LED flashes
alternately with the LED located beneath the storage
symbol (8) while the beeper sounds for 60 sec, and the
scrolling text appears “End Cycle - Fine Ciclo”. After this
time, the chilling LED (9) switches off, the storage one
starts flashing (8) and the scrolling text disappears (even
when the beeper silencer button (7) is pressed.
The LED (8) will flash when the compresser is on while if
the set value has been reached, they will only remain lit
until transition to storage. Similarly with storage, the LED
(9) will flash when the compressor is active and will remain
lit for the rest of the storage.

“intensity” of chilling. The “Time” or “Temperature” chilling
mode will be set by pressing the button (5). Lighting up of
the corresponding LEDs on the sides will define the type
of chilling.
Each time the positive chilling button (2) is pressed the
display will show successively for 3 seconds one of the
following cycles:
LIGHT, SOFT, MEDIUM, FAST.
Each time the negative chilling button (3) is pressed the
display will show successively for 3 seconds one of the
following cycles:
LIGHT, SOFT, HARD, RUN.
7.3 - Selecting and starting the positive chilling cycle
When the button (2) is pressed for the first time, “SOFT”
mode will be selected, represented with lighting up of
two of the four LEDs (24); subsequent pressing takes to 3
and 4 LEDs lit and results in the “HARD” mode. Successive
pressing reduces from 4 to 1 the LEDs lit and so on.
cooling in the presence of products that are resistant and
very hot initially.
Once the MEDIUM or FAST cycles are started, to modify the
HARD phase duration simply press the button (2) that will
show on the display (19) the words “Hard” and will result
in flashing on the display (18) the value in minutes of the
HARD phase. With the +/- buttons it is possible to increase
or decrease the value and confirm with the button (2) or
wait 5 seconds (N.B. THE CHANGED VALUE ONLY APPLIES
TO THE CYCLE IN PROGRESS).
Once the cycle is selected, it is necessary to select the Time
or Temperature mode by pressing the button (5) until
coming on of the relevant LED.
At this point to start the cycle press the START/STOP
button (22).
In the even of Temperature chilling, it is possible to
change this chilling end value by pressing the button (2)
or (3) depending on the type of chilling in process. Having
pressed the button, the display (18) will appear the value
of the end chilling temperature set, which can be modified
within the envisaged range. Having pressed the button (2)
or (3) or after 5 seconds the changed value is saved.
7.4 - Selection and starting the Negative chilling cycle
“LIGHT” - 1 LED only on
In this condition, there will be a cell temperature set of
27F (-3C). This avoids the risk of ice formation during the
positive chilling phase and it will be used for loads which
can be damaged by excessively heavy treatment.
“SOFT” - 2 LEDs on (default)
In this condition, there will be a cell temperature set of 23F
(-5C). This set will allow quicker chilling for products that
in any case are fairly resistant to the freezing process.
“MEDIUM” - 3 LEDs on
In this condition, there will be an initial cell temperature
set of -4F (-20C); after the HARD time, this will be taked to
a cell temperature of 24F (-3C). This method accelerates
cooling in the presence of products that are resistant and
very hot initially.
“FAST” - 4 LEDs on
In this condition, there will be an initial cell temperature
set of -4F (-20C), after the HARD time, this will be taken to
a cell temperature of 23F (-5C). This method accelerates
Pressing the button (3) for the first time will select the
“HARD” mode, represented by coming on of three of the
four LEDs (23) present. Subsequent pressing will take to
4 the LEDs lit and will return into “RUN+HARD” mode.
Successive presses reduce from 4 to 1 the LEDs and so on.
“LIGHT” - 1 LED only on
In this condition, there will be a cell temperature set of
23F (-5C); after the SOFT time defined by the parameter
(ts) this will move to a temperature of -22F (-30C). This
mode is for use on large pieces where it is important to
homogenise the chilling cycle.
“SOFT” - 2 LEDs on
In this condition, there will be a cell temperature set of
-4F (-20C); after the SOFT time defined by the parameter
(ts) this will move to a temperature of -22F (-30C). This
mode is for use on large pieces where it is important to
homogenise the chilling cycle.
In the case of SOFT or LIGHT temperature chilling, the
set change will be decided by the product temperature
detected according to the parameter (C2).
