Deep Fryer Operation and Oil Change SOP Template

1.Purpose

To operate deep fryers safely, keep frying oil at a usable quality, and change oil on a schedule that protects food quality and staff safety.

2.Scope

Applies to all deep fryers and the oil used in them, from daily startup and filtering through scheduled oil changes and fryer boil-outs.

Definitions

TPM level

Total polar materials, a measurement of oil breakdown checked with test strips to decide when oil needs changing.

Boil-out

A deep clean of the fryer using water and a fryer-safe cleaner to remove carbon buildup, done with the oil removed.

Smoke point

The temperature at which oil starts to smoke and break down, a sign it is overheating or degrading.

3.Responsibilities

Line Cook

Operates the fryer during service, filters oil, and reports any smell, smoke or performance problem.

Kitchen Manager

Tests oil quality, schedules oil changes and boil-outs, and manages used oil disposal.

Executive Chef

Sets frying temperatures by menu item and reviews fried food quality.

R = Responsible, A = Accountable, C = Consulted, I = Informed

5.Procedure

1. 5.1

   Inspect the fryer before startup

   Line Cook

   Check that the fryer is clean, the oil level is between the fill lines, and the area around the fryer is clear and dry before turning it on.

2. 5.2

   Heat oil to the correct frying temperature

   Line Cook

   Turn on the fryer and let the oil reach the temperature set for the menu item being fried, checking the thermostat display or a probe thermometer.

   Checkpoint: Oil reaches the target frying temperature set by the executive chef before food goes in.

3. 5.3

   Load the fryer basket correctly

   Line Cook

   Lower food into the basket gently and away from your body, and avoid overfilling the basket so oil temperature does not drop too far.

   Warning: Lower food into hot oil slowly to avoid splashing, and never drop items in from above.

4. 5.4

   Monitor frying time and appearance

   Line Cook

   Watch the timer and the color of the food, removing it once it reaches the target color and internal temperature for the item.

5. 5.5

   Skim and filter oil between batches

   Line Cook

   Skim loose food particles out of the oil between batches using a strainer so they do not burn and affect the taste of later batches.

6. 5.6

   Filter the oil after each shift

   Line Cook

   Once the fryer has cooled to a safe filtering temperature, filter the oil through the filtering system or filter paper to remove sediment before storing or reusing it.

   Warning: Let the oil cool to a safe handling temperature before filtering or moving it, since hot oil can cause severe burns.

7. 5.7

   Test oil quality daily

   Kitchen Manager

   Dip a test strip into the oil and compare the color to the chart on the box to check the oil's TPM level before deciding to keep, filter or change it.

   Checkpoint: Oil TPM level is checked and recorded before the fryer is used each day.

8. 5.8

   Watch for signs the oil needs changing

   Kitchen Manager

   Change the oil if it is dark, foaming, smells off, smokes below the normal frying temperature, or fails the test strip, rather than waiting for a fixed calendar date alone.

9. 5.9

   Drain and dispose of used oil safely

   Line Cook

   With the fryer cooled, drain the old oil into a heat-resistant container and move it to the designated used oil recycling container, never down a drain.

   Warning: Never pour used fryer oil down a drain. Use the designated recycling container.

10. 5.10

    Boil out and clean the fryer

    Line Cook

    On the scheduled boil-out day, clean the empty fryer with water and a fryer-safe cleaner following the manufacturer's steps, then rinse thoroughly and dry.

11. 5.11

    Refill with fresh oil

    Kitchen Manager

    Fill the clean, dry fryer with fresh oil to the fill line, and record the oil change date on the fryer log.

12. 5.12

    Shut down the fryer at close

    Line Cook

    Turn off the fryer, let it cool, cover it if required, and confirm the surrounding area is clean and free of oil residue before leaving it for the night.

6.Quality checks

• →Oil TPM level is tested and logged daily before use.
• →Fried food reaches its target color and internal temperature consistently.
• →Used oil is disposed of only through the designated recycling container.
• →Fryer boil-outs happen on the scheduled frequency with no skipped cycles.

7.Records

• →Fryer oil test and change log
• →Fryer boil-out and cleaning log
• →Used oil recycling pickup receipts

8.KPIs

• →Average oil life in days or frying hours before change
• →Percent of daily oil tests completed on schedule
• →Fried food quality complaints per month
• →Oil cost per week versus target

9.Common mistakes

• →Waiting for a fixed calendar date to change oil instead of testing its quality.
• →Pouring used oil down a floor drain instead of using the recycling container.
• →Filtering or draining oil while it is still very hot.
• →Overfilling the fryer basket, which drops oil temperature and leaves food greasy.
• →Skipping the scheduled boil-out because the fryer looks clean enough.
