Recovery Time
Recovery time is a method of measuring a fryer’s performance. Put simply, it is the time required for
the fryer to increase the oil temperature from 250°F to 300°F (121°C to 149°C). This range is used
as a standard since ambient kitchen temperatures can affect the test if lower ranges are used.
The Computer Magic III.5 performs the recovery test each day as the fryer warms up. An operator
can view the results of the test any time the fryer is above the 325°F (163°C) point by pressing the
button and entering the code 1652. The test results will be displayed in the computer’s LED
panel in minutes and seconds. An acceptable recovery time for the MJCF Series fryers is 3 minutes,
30 seconds.
