USE AND MAINTENANCE MANUAL
ZERO TOUCH
5.5 USE OF THE LAMP UV (OPTIONAL)
The UV lamp sterilizing function (optional) must only be used for the purpose for which it was
designed: sterilize internal unit surfaces.
Attention
Avoid exposure and / or observation of UV lamps.
PRE-COOLING
Prior to carrying out either fast blast chilling or freezing operations, it is necessary to pre-cool
the system in order to further reduce operating times.
Therefore, carry out a Soft/Hard unloaded cycle before inserting products for blast chilling.
Warning
To avoid damaging the machine, do not leave hot products inside the chamber for periods of time.
Start the blast chilling or freezing cycle as soon as the product has been introduced into
the machine.
TEMPERATURE
Avoid leaving cooked products due to be blast chilled or frozen for long periods at room
temperatures. The more water content lost, the less succulent the product will be following treatment.
It is recommended to begin the fast blast chilling or freezing cycle as soon as the product preparation
/cooking has ended. The food can be inserted in the blast chilling chamber even at relatively high
temperatures (>100 °C) as long as the unit has been pre-cooled. It should be remembered that blast
chilling cycle times range from +90 °C (from +90 °C to +3 °C for the fast blast chilling cycle: from +90
°C to -18 °C for the fast freezing cycle).
PRESERVATION
Blast chilled or frozen foods should be appropriately covered and protected
(with cling-fi lm, sealed lid or, better still, vacuum sealed). They should be identifi ed by an
adhesive label, detailing in indelible ink contents, preparation date and expiry date.
Blast chilled foods must be kept in a refrigerated environment at a constant temperature
of +2 °C.
Frozen foods must be kept in a refrigerated environment at a constant temperature of -20°C.
Attention
Do not use the blast chiller as a standard refrigerator.
