• Record mixing speed at defined intervals (e.g., every 15 minutes).
• Ensure that speed fluctuations are within acceptable limits.
• If speed deviations occur, document and take corrective actions.

5.4 Speed Adjustment Guidelines

• If the mixture is too thick, increase speed gradually.
• If excessive foaming occurs, reduce speed and use defoaming agents if required.
• Ensure speeds are within optimal shear stress limits to prevent ingredient degradation.

5.5 Post-Mixing Verification

• Check the final homogeneity of the batch.
• Perform a viscosity test to confirm consistency.
• Ensure that no unmixed particles or phase separation are present.

5.6 Documentation

• Record all mixing speed readings in the Mixing Speed Log.
• Document any speed adjustments made during processing.
• QA personnel must review and approve the log before batch release.
