OPERATING MANUAL
LOADING THE APPLIANCE / POSITIONING THE TRAYS
Fig. 8
Do not place the products to be cooled one on top of the other. The thickness must be less than 50 mm for blast
freezing and less than 80 mm for blast cooling (Figure 8).
Ensure that the space left between the trays is enough to allow air to circulate properly (Figure 9).
Place the trays in the rear of the room, close to the fan (Figure 10).
If the cabinet contains less than the maximum number of trays, space out the trays at an equal distance from one
another (Figure 11).
STORAGE TIMES
After chilling or cooling, a cooked product can be kept in a refrigerator after the blast cooling process. Ensure that
the temperature during storage is always between 0°C and 4°C, depending on the type of foodstuff. Storage time
may be increased to approximately two weeks by using vacuum processing.
After blast freezing, a cooked product can be kept safely for a period of 3 to 18 months, depending on the type of
foodstuff.
During this time, the temperature must be kept at -18°C or lower. Do not store cooked products at room tempera-
ture before they are blast cooled, avoiding any loss of moisture and ensuring the foodstuff retains its freshness.
