Heat Treatment Cycle
The function of the Heat Treatment Cycle is to raise
the temperature of the mix in the freezing cylinder(s)
and hopper(s) high enough and quickly enough to
destroy bacteria. When this has been accomplished,
the temperatures must then be returned to a
temperature low enough and quickly enough to
retard spoilage.
The Heat Treatment Cycle must be successfully
completed at least once every 24 hours or the
freezer will automatically lock itself in the STANDBY
mode.
Single freezing cylinder operation is now available.
The software keeps track of the freezing cylinder(s)
“in use”. Therefore, the Heat Treatment Cycle can
now be performed on only one side, if the other side
has not been placed in AUTO or STANDBY since
the unit was last brush cleaned.
The Heat Treatment Cycle may be started
automatically according to the AUTO HEAT CYCLE
TIME.
IMPORTANT: The freezer must be operating in
either the STANDBY or AUTO mode before a Heat
Treatment Cycle can be started.
There are three phases in a Heat Treatment Cycle:
Heat, Hold and Cool.
The Heat Phase
During this phase, the temperatures of the product
in the freezing cylinder and hopper are raised over
151.5
_
F (66
_
C) in 90 minutes or less.
The Heat Phase Timer “times out” the maximum
allowable amount of time the unit can remain in the
HEAT phase of the Heat Treatment Cycle. If the
timer exceeds 90 minutes, the unit will lock-out.
The Hold Phase
During the HOLD phase, the temperature of the
product is “held” over 151.5
_
F (66
_
C) for a minimum
of 30 minutes to ensure the destruction of all harmful
bacteria in the product.
The Hold Phase Timer “times out” 30 minutes as
long as all freezing cylinder and hopper
temperatures remain above 151.5
_
F (66
_
C) for the
duration of the HOLD phase.
The Heat Soak Timer prevents the HOLD phase
from entering the next COOL phase of the cycle until
the 30 minutes is satisfied and until the total time of
the HEAT and HOLD cycles combined is greater
than 115 minutes.
The Cool Phase
During the COOL phase, the product in the freezing
cylinder and the hopper are lowered to 41
_
F (5
_
C)
or less. The unit must complete this phase in less
than 120 minutes.
The COOL Phase Timer measures the maximum
allowable time the unit can remain in the COOL
phase. If the timer exceeds 120 minutes, the unit will
lock-out.
The Heat Cycle TT (Total Time) Timer “times out”
the maximum allowable time the unit can remain in
the Heat Treatment Cycle (4 hours). If the timer
exceeds four hours, the unit will lock-out. This timer
is a combination of the HEAT, HOLD, and COOL
Phase Times.
When the entire Heat Treatment Cycle has been
completed, the normal display will appear, indicating
that the machine is operating in the STANDBY
mode.
