later in this chapter, you may choose to chill by time, or by using the food
probe to chill to a set core temperature. If the time mode is selected, then the
Blast Chilling cycle will terminate by elapsed time. In the latter case, the
product may or may not reach the desired core temperature. In the food probe
mode, Blast Chilling will be controlled by the food probe and may take more or
less time, depending on the product weight, density, thickness, starting
temperature and so on to reach the target temperature. In either mode, once
the time has elapsed or the food probe temperature is reached, the machine
will then switch to the hold mode automatically and maintain the product at the
storage temperature. Users will chill by time when are aware of the fact that
food end temperature is not ruling the cycle and is not determining the time to
stop it (the pre-selected time will determine the cycle end instead). Or
otherwise they will select a core temperature based cycle when they want to be
sure that the food temperature before going into holding mode matches with
food safety guidelines (3°C-37°F).
Automatic Defrost
Evaporator will defrost automatically between chilling and hold and will
terminate once the ice on the evaporator is totally melted.
Blast Chilling Cycle Activation
When the Blast Chilling mode is selected, the machine will automatically Pre-
chill the cabinet to -5°C(23°F). Once it reaches the pre-chill temperature, then
either a manual cycle or a recipe can be started.
