Meta Description: This document outlines the Design Qualification Protocol for the Twin Screw Extruder used in the production of solid dosage forms, focusing on critical parameters and acceptance criteria.
Tags: Equipment Validation, Design Qualification, Twin Screw Extruder, Solid Dosage Form, Production
Objective
The objective of this Design Qualification (DQ) Protocol is to establish and document the validation requirements for the Twin Screw Extruder used in the production of pellets and solid dispersions, ensuring compliance with regulatory standards and internal quality requirements.
Scope
This protocol applies to the Twin Screw Extruder utilized in the production area for solid dosage forms, specifically for the extrusion of pellets and solid dispersions. It covers the validation of equipment and its critical parameters.
Responsibilities
The following roles are responsible for the execution and approval of this DQ Protocol:
- Validation Team: Responsible for protocol execution and documentation.
- Quality Assurance: Responsible for review and approval of the protocol.
- Production Team: Responsible for equipment operation and maintenance.
Prerequisites
- Completion of User Requirement Specification (URS) for the Twin Screw Extruder.
- Installation Qualification (IQ) must be completed prior to DQ execution.
Equipment Description
The Twin Screw Extruder is designed for the extrusion of pellets and solid dispersions. It operates under controlled conditions to ensure product quality and consistency. Key features include:
- Screw speed control
- Temperature control zones
- Torque monitoring
Test Plan
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| TQ-001 | Verify screw speed settings | Within specified range as per URS Annex11 | Calibration records |
| TQ-002 | Check temperature zones | All zones must be within specified limits | Temperature logs |
| TQ-003 | Monitor torque readings | Torque must remain within operational limits | Torque data logs |
Detailed Test Cases
Test Case ID: TQ-001
Objective: To verify that the screw speed settings are within the specified range.
Procedure:
- Set the extruder to the desired screw speed.
- Record the actual screw speed.
Acceptance Criteria: The recorded speed must fall within the range defined in URS Annex11.
Evidence: Calibration records and speed logs.
Test Case ID: TQ-002
Objective: To ensure temperature zones are operating within specified limits.
Procedure:
- Set the temperature for each zone.
- Monitor and record the temperature for each zone during operation.
Acceptance Criteria: All temperature zones must remain within the specified limits.
Evidence: Temperature logs and monitoring records.
Test Case ID: TQ-003
Objective: To monitor torque readings during operation.
Procedure:
- Run the extruder at the specified speed.
- Record torque readings during operation.
Acceptance Criteria: Torque must remain within operational limits as defined in the URS.
Evidence: Torque data logs and monitoring records.
Deviations
Any deviations from the acceptance criteria must be documented and investigated. A corrective action plan should be developed for any critical deviations identified during testing.
Approvals
This protocol must be reviewed and approved by the Quality Assurance Department prior to execution.
