DETAILS (Continued)
The number of “Beeped ‘DONE’ Too Long” cycles for this batch of
peanut oil is reported next. Note that this value does not yet include the
cook cycles from today.
“D8: BEFORE TODAY “
“D8: 7% OF LOADS”
“D8: BEEPED ‘DONE’”
“D8: TOO LONG”
“D8: ON THIS OIL”
(Press the DOWN button...)
Finally, the controller identifies percentage of “Beeped ‘DONE’ Too
Long” cook cycles for the previous batch of peanut oil:
“D8: LAST OIL”
“D8: 6% OF LOADS”
“D8: BEEPED ‘DONE”
“D8: TOO LONG”
D 9: Irregular Loading Report
For most cook cycles, the controller determines when the product was
placed into the peanut oil. This report identifies the percentage of
cycles for which this determination was not successful.
The controller continually monitors the temperature and notes sudden
changes. When the user presses the button to start a cook cycle, the
controller checks to see if any sudden change was observed prior to the
start of the cycle. If a sudden temperature drop was noted in the [90]
second period before the start of the cook timer, the controller
interprets this to be the moment when the product was placed into the
peanut oil. The cooking timer then adjusts accordingly.
This “drop detection” detects most loads, but can fail for several
reasons. Anytime the detection routine fails to find the true drop point,
the controller logs an “Irregular Loading” count.
Examples of failed “drop detection” might be: the Operator takes more
than [90] seconds from the time he starts loading the product to the time
he presses the start button, or the Operator cooks a very light product
load, one or two filets, for example.
In these instances, no drop point will be found and that cook cycle
counts as an “Irregular Loading” cycle. Only products that have more
than 5% of loads with missed detection’s are reported.
