Check a dairy clean-in-place (CIP) alkali cycle against its temperature, time and concentration limits, and keep the record on this device.

Temperature (°C)
Equation: Checks: temperature 70–80 °C; contact time at least 15 minutes; caustic concentration 1.0–2.0%. Pass count = number of checks met. Overall = pass only when all three pass.
Method: Alkali CIP cycle check against the usual dairy CIP ranges (alkali wash 70–80 °C for 15–30 minutes at 1–2% caustic, per plant CIP practice and EHEDG hygiene guidance). The limits here are the common defaults — your plant SOP governs.
Assumptions: the temperature, time and concentration are the values held through the cycle, not single-point readings; the cycle is the alkali stage of a full CIP.
Limitations: three checks do not prove a clean plant — rinse, acid stage, flow and visual or ATP checks are separate; the ranges are defaults, not your plant’s validated limits.
Rounding: temperature to 1 decimal place; concentration to 2 decimal places; time to the nearest minute; intermediates unrounded.

Worked example: Alkali at 75 °C for 20 minutes at 1.5% caustic. Temperature 70–80 °C: pass. Time at least 15 minutes: pass. Concentration 1.0–2.0%: pass. 3 of 3 checks passed — overall pass.
