Approved By: [Approver’s Name]
Objective
The objective of this Design Qualification (DQ) protocol is to establish documented evidence that the Sigma Mixer / Kneader is designed and installed in compliance with the User Requirements Specification (URS) for high-viscosity mass mixing in the Solid Dosage Form production area.
Scope
This protocol applies to the Sigma Mixer / Kneader utilized in the Production/Granulation area for the manufacturing of solid dosage forms. The DQ will cover the equipment’s design specifications, installation, and operational performance.
Responsibilities
- Validation Team: Responsible for the execution and documentation of the DQ protocol.
- Quality Assurance: Responsible for reviewing and approving the DQ protocol and reports.
- Engineering: Responsible for providing technical specifications and installation support.
Prerequisites
- Completion of User Requirements Specification (URS).
- Installation of the Sigma Mixer / Kneader as per manufacturer’s guidelines.
- Availability of operational manuals and training for personnel.
Equipment Description
The Sigma Mixer / Kneader is a high-viscosity mass mixing equipment designed for the production of solid dosage forms. It features adjustable blade speed, temperature control, and vacuum capabilities to ensure optimal mixing conditions.
Test Plan
| Test ID | Procedure | Acceptance | Evidence |
|---|---|---|---|
| T1 | Verify blade speed settings. | Blade speed within specified range. | Calibration report. |
| T2 | Check temperature control functionality. | Temperature maintained within specified limits. | Temperature log. |
| T3 | Assess vacuum operation. | Vacuum levels meet specifications. | Vacuum gauge readings. |
Detailed Test Cases
Test Case 1: Blade Speed Verification
Procedure: Set the mixer to the specified blade speed and record the actual speed.
Acceptance Criteria: The actual blade speed must be within ±5% of the specified speed.
Evidence: Calibration report and speed measurement log.
Test Case 2: Temperature Control Assessment
Procedure: Run the mixer and monitor the temperature for stability over a 30-minute period.
Acceptance Criteria: The temperature must remain within ±2°C of the target temperature.
Evidence: Temperature control log.
Test Case 3: Vacuum Operation Evaluation
Procedure: Engage the vacuum and monitor the levels during operation.
Acceptance Criteria: Vacuum levels must reach and maintain the specified threshold.
Evidence: Vacuum gauge readings documented during operation.
Deviations
Any deviations from the acceptance criteria must be documented and assessed for impact on the validation process. A corrective action plan must be developed if critical parameters are not met.
