Heat Treatment Graph
The purpose of the HEAT phase is to raise the
product temperature above 150
_
F (65
_
C) within 90
minutes. To satisfy the control system, the product
must actually reach 160
_
F (71
_
C) in the freezing
cylinder and 155
_
F (68
_
C) in the hopper. This
requirement ensures that the 150
_
F (65
_
C)
requirement has been met. Health laws require
these parameters to be 150
_
F (65
_
C) in 90 minutes;
however, the actual amount of time the freezer takes
to accomplish this requirement is closer to 60
minutes.
While in the COOL phase, the hopper and freezing
cylinder are operated by Standby temperatures of:
Freezing Cylinder:
30.5
_
F (-.83
_
C) and above
“ON”
ON
26.5
_
F (-3.1
_
C) “OFF”
Hopper:
39
_
F (3.9
_
C) and above “ON”
37
_
F (2.8
_
C) “OFF”
The COOL Phase concludes when the hopper and
freezing cylinder reach 41
_
F (5
_
C). At this point the
machine enters Standby operation. While the time
given for the COOL Phase is 90 minutes, the actual
time is closer to 30 minutes.
