3.6.2. Pre-cooling
Before a cycle of blast chilling and/or shock freezing, it is
essential to pre-cool the chamber in order to further
reduce work time. Therefore, before inserting the product
to be blast chilled, carry out an empty SOFT or HARD
cycle.
Do not leave the hot product inside of the cham-
ber, in order to avoid damaging the machine.
As soon as the product to be treated is inserted,
start the blast chilling or shock freezing cycle
right away.
3.6.3. Core probe
The core probe must be positioned correctly at the centre
of the largest piece or cut of the product. Make sure that
the point of the probe does not come out of the product
or touch the tray. The probe must be cleaned and saniti-
sed before each work cycle in order to avoid unwanted
contamination.
For better results, load the GN1/1 containers with a
product weighing 3.5 kg and with a maximum thickness
of 8 cm for blast chilling, or 5 cm for shock freezing.
For difficult products and/or fats, reduce thickness even
more.
If the machine is not loaded completely, concentrate the
trays in the middle of the blast chiller, placing an empty
tray (A) above the last one.
Position the trays in the innermost part of the tray-holder,
making sure that they are as close as possible to the
evaporator.
Do not overload the machine beyond what the manufac-
turer has established (Tab. “Tray yield and capacity”).
