standards. The QA Manager is responsible for ensuring that quality checks are performed regularly and that the tube-filling machine is operating within specifications.

5. Procedure

5.1 Pre-Operation Setup

1. Ensure that the tube-filling machine is clean and properly maintained according to the cleaning SOP.
2. Verify that the correct filling tubes, caps, and labels are available and free of defects.
3. Ensure that the cream product to be filled is properly mixed, homogenized, and at the correct temperature for filling.
4. Check that all necessary materials (e.g., labels, caps, and tubes) are prepared and positioned for easy access during the filling process.
5. Verify that the tube-filling machine is set to the correct filling parameters, including speed, volume, and temperature settings, as specified for the production run.
6. Ensure that the machine’s calibration is checked, and it is functioning properly before starting the filling process.

5.2 Operating the Tube-Filling Machine

1. Start the machine following the manufacturer’s start-up procedure. Ensure that all parts are functioning smoothly and that no unusual sounds or vibrations are present during startup.
2. Begin the tube-filling process. Ensure that each tube is properly positioned under the filling nozzle and that the correct amount of cream is dispensed into each tube.
3. Monitor the filling process for consistency and accuracy. If the machine is dispensing more or less than the required volume, stop the machine immediately and adjust the settings.
4. Check that the tubes are being filled uniformly and that the cream does not spill over or underfill the tubes.
5. Verify that the tubes are properly capped and sealed after filling. Ensure that the capping mechanism works correctly and that there are no leaks or damage to the caps.

5.3 Monitoring During Operation

1. Continuously monitor the tube-filling machine during operation for any signs of malfunction or errors, such as tube misalignment or excessive filling.
2. Inspect a sample of filled tubes periodically to ensure that the filling volumes are within the specified tolerance limits.
3. If any defects or inconsistencies are detected, stop the machine and address the issue immediately. Record any corrective actions taken in the Production Log (Annexure-1).
4. Ensure that the filled tubes are correctly labeled, with no misprints or errors in labeling. Verify that the labeling machine is correctly aligned with the filling machine.

5.4 Troubleshooting

1. If the tube-filling machine malfunctions or there are issues such as inconsistent filling volumes, clogged nozzles, or improper sealing, stop the machine and troubleshoot the issue following the manufacturer’s troubleshooting guide.
2. Common issues may include air bubbles in the cream, nozzle blockages, or improper machine calibration. Address these issues by cleaning the nozzles, adjusting the machine settings, or refilling the cream reservoir as necessary.
3. If the problem persists, contact the maintenance team for further inspection and repair.
4. Document any issues and corrective actions taken in the Equipment Maintenance Log (Annexure-2) or Production Log (Annexure-1).

5.5 Post-Operation Cleaning and Shutdown

1. Once the production run is complete, stop the machine following the manufacturer’s shutdown procedure. Turn off the power supply and disconnect any utilities as needed.
2. Clean the filling nozzles, tubes, and all other components that came into contact with the cream. Follow the cleaning SOP for the tube-filling machine.
3. Ensure that the machine is free from product residues and is properly sanitized before the next production run.
4. Record the shutdown time, cleaning activities, and any maintenance performed in the Equipment Maintenance Log (Annexure-2).

5.6 Documentation

1. Record all operational details, including start-up and shutdown times, volume dispensed, and any issues encountered, in the Production Log (Annexure-1).
2. Document any machine adjustments, calibration checks, and maintenance activities in the Equipment Maintenance Log (Annexure-2).
3. Ensure that any discrepancies found during production (e.g., underfilling or overfilling) are documented along with the corrective actions taken.

5.7 Final Approval

1. The QA team must review all documentation related to the tube-filling process, including the Production Log and Equipment Maintenance Log, to ensure compliance with SOPs and product specifications.
2. Once approved, the tube-filling machine is cleared for use in the next production run. If any deviations are noted, corrective actions should be taken before continuing production.
