Standard Operating Procedure for Operation of High Shear Mixer

1. Purpose

The purpose of this Standard Operating Procedure (SOP) is to outline the procedure for the proper operation of a high shear mixer in pharmaceutical manufacturing to achieve effective blending and mixing while maintaining safety and compliance with Good Manufacturing Practices (GMP).

2. Scope

This SOP applies to all personnel involved in the operation of high shear mixers within the pharmaceutical manufacturing facility.

3. Responsibilities

Production Operator: Responsible for carrying out the operation of the high shear mixer as per this SOP.
Supervisor: Oversees the operation and ensures compliance with this SOP.

4. Procedure

4.1. Pre-Operation Checks

Inspect the high shear mixer for any visible damage, leaks, or defects. Report any issues to the supervisor.
Ensure that the equipment is clean and free from any residues or contaminants from previous operations.
Verify that all necessary utilities (e.g., electricity) are available and functioning properly.

4.2. Set-Up

Position the high shear mixer in the designated location for operation.
Attach the appropriate mixing tool (e.g., rotor-stator, impeller) as specified in the batch record or formula.
Ensure that all connections are securely fastened and properly aligned.

4.3. Ingredient Preparation

Weigh and measure the required raw materials and ingredients according to the approved batch record or formula.
Prepare the ingredients and ensure they are ready

for blending and mixing.

4.4. Mixing Process

Start the high shear mixer according to the manufacturer’s instructions and the parameters specified in the batch record.
Gradually add the ingredients to the mixer vessel in the specified order or as per the formula.
Monitor the mixing process closely to ensure that the materials are effectively blended and mixed to the desired consistency.
Record the mixing time, mixing speed, and any deviations from the standard procedure.

4.5. Post-Mixing Checks

Stop the high shear mixer and ensure it is properly cleaned and sanitized after use.
Perform visual inspections and quality checks of the mixed product to check for any abnormalities or inconsistencies.
Compare the final product with the quality specifications and document any deviations.

4.6. Documentation

Properly document all aspects of the high shear mixer operation, including batch records, ingredient measurements, mixing parameters, and any deviations from the procedure. Maintain records in a secure and accessible location for regulatory inspection.
