7.3.3. AUTOMATIC BLAST CHILL/SHOCK FREEZE CYCLE WITH MULTI-POINT PIN PROBE
Insert the pin probe with the fi rst sensor as far as possible into the core of the product.
Select the desired cycle +3ºC soft or hard or -18ºC soft or hard by using the appropriate buttons

of the hottest sensor selected by the control, while DISPLAY 1 indicates the temperature of this sensor.
Within the fi rst 3 minutes, the electronic control performs a pin probe insertion test to verify the ef-
fective application of the probe in the product to blast chill (fl ashing pin probe symbol).
If the pin probe is inserted badly or left in the holder provided, the cycle is automatically converted to timer.
Through functions controlled by the electronic probe, the cycle terminates when the temperature of
the probe at the core reaches the value entered (+3ºC for blast chilling, -18ºC for shock freezing).
Upon termination of the blast chill cycle the machine automatically continues on to the conservation phase.

7.3.4. BLAST CHILL OR SHOCK FREEZE CYCLE WITH 2 – 3 – 4 STANDARD PIN PROBES
This cycle can be run with several standard single-point pin probes.
Select the cycle desired, e.g.:
ton to start the cycle.
When the temperature of a probe reaches the value entered for the blast chill/shock freezer cycle
(Fig.9)
selected, this is signalled with a buzzer, and DISPLAY 3 fl ashes the number of the relevant pin probe
(Fig.9). If in the meantime the other probes reach core temperature, the signal is placed in a queue.
The signals terminate and the buzzer switches off only when the door is opened.
Once the door is closed and the other probes reach core temperature, a new signal appears on
DISPLAY 3 (Fig.10) which indicates the number of the probe of the blast chilled/shock frozen product.
(Fig.10)
If blast chilling is not complete within the determined time, the buzzer activates for one
minute and can be switched off by pressing any button.
The blast chill phase continues but the clock and HACCP symbols fl ash and the alarm is memorised in
the HACCP records. The code AL5 fl ashes on DISPLAY 1. (Fig.11).
The alarm cancels automatically when passing to the conservation phase and the HACCP symbol
(Fig.11)
remains on.
Upon termination of the cycle the machine automatically proceeds to the conservation phase. see 7.3.7.
