How to Use This Calculator
- Enter the starting temperature when cooling began (°F) and the current measured temperature.
- Enter elapsed time in minutes since cooling started.
- Select the cooling method (FDA 2-Stage: 135→70→41 °F, or one-stage).
- The calculator shows cooling rate, projected total time, stage 1 compliance status, overall compliance, minutes remaining, and required rate to stay compliant.
- If cooling rate is insufficient, use an ice bath, blast chiller, or smaller portion containers to accelerate the process.
