The HEAT CYCLE DATA Details record the temperature
in the freezing cylinders and mix hoppers every 5
minutes during the Heat Treatment cycle. Up to 366 Heat
Treatment cycles are recorded. The time and
temperature are displayed for the left hopper, left barrel,
right hopper, and right barrel for each phase during the
Heat Treatment cycle. An individual phase or a complete
Heat Treatment cycle containing all four phases can be
viewed.
Heat Treatment Phases
In the HEAT CYCLE DATA screen, select the Auto
symbol to move the arrow up to Details, and then
select the Calibrate symbol . (See Figure-227.)
Figure-227
The most recent Heat Treat Cycle record (Recd 1) is
displayed with the date and time. Access a different Heat
Treatment cycle record by selecting the optional Flavor
symbol to move the arrow to Next record, and select
the Calibrate symbol . Repeat this step until the
desired record with the date and time is displayed.

Note: An L or an H displayed to the left of the
temperature reading indicates the temperature was the
lowest or highest recorded during the phase.
HEAT The phase that heats the mix in the barrels
and hoppers to 151°F (66.1°C).
HOLD The phase that maintains the mix
temperature above 151°F (66.1°C) for a
minimum of 30 consecutive minutes.
SOAK The additional heating time that may follow
the Hold phase to ensure the total Heat,
Hold, and Soak time is not less than 115
minutes.
COOL The phase that refrigerates the mix until all
four temperature zones are cooled below
41°F (5°C).
