D 5: Cook Times (Slow Cooks) Report
This section summarizes the slow cooking status for each product.
Actual cook times for Cook Cycles can vary from the programmed
cook time setting, due to the load compensation feature. Load
Compensation slows the cook timer down when the actual peanut
oil temperature is below a reference value, and speeds up the
cook timer countdown when peanut oil temperature is above the
reference.
When the peanut oil temperature is lower than expected during a
Cook Cycle, the overall cook time will be longer than normal. If
the actual cook time stretches beyond a programmed limit, the
controller counts a "SLOW COOK"
the end of the Cook Cycle.
If low voltage or low amps are detected during the Cook Cycle, the
warning message indicates
but the cycle will still count as a "slow cook". If the voltage and
amps have been fine during the Cook Cycle but the cycle was
started before the Ready light came on, then the warning message
indicates "SLOW COOK — WAIT FOR READY
Otherwise, the slow cooking problem will be attributed to a "bad
batch" of product: cooking too much in one load, or cooking
product that is too cold (i.e. frozen product on a pressure fryer
when the product should be fresh).
If none of the products has more than 5% slow Cook Cycles today,
the following report is made:
"D5: COOK TIMES"
"D5: LOOK OK"
"D5: TODAY"
