Pharma Powder Transfer System – Working & Key Features

A Pharma Powder Transfer System (PTS) is designed for the safe, efficient, and contamination-free transfer of powders in pharmaceutical manufacturing. It ensures compliance with cGMP (Current Good Manufacturing Practices) and regulatory standards like FDA, EU GMP, and US Pharmacopeia.

Working Principle of a Pharma Powder Transfer System

1. Powder Loading

• The powder is manually or automatically fed into the system from drums, bags, silos, or bins.
• Some systems include glove boxes, containment isolators, or sieves for sterile handling.

2. Powder Conveying Mechanism

Pharma transfer systems primarily use vacuum conveying due to its dust-free and closed-system benefits. The key methods include:

A. Vacuum Powder Transfer System (Negative Pressure)

• A vacuum pump creates suction in the transfer line.
• The powder moves through the pipeline into a receiving vessel.
• A filter separator captures fine particles, ensuring product integrity.
• Ideal for hygienic and sterile applications like API (Active Pharmaceutical Ingredient) transfer.

B. Pressure Conveying System (Positive Pressure)

• Uses compressed air or inert gas (e.g., nitrogen) to push the powder.
• Can be used for dense phase (gentle transfer) or dilute phase (fast transfer) applications.
• Suitable for bulk transfer of excipients and granules.

C. Contained Transfer Using Split Butterfly Valves (SBV)

• A closed docking system prevents contamination and exposure.
• Used for high-potency drugs and hazardous powders.

3. Powder Separation & Filtration

• The transferred powder is collected in a process vessel, reactor, or mixing tank.
• A HEPA filter or cyclone separator removes airborne particles.
• Ensures containment and prevents cross-contamination.

4. Discharge & Collection

• The powder is discharged into tablet press machines, blenders, or granulation units.
• Precise dosing and batch control ensure consistent product quality.

5. Cleaning & Validation

• CIP (Clean-in-Place) or WIP (Wash-in-Place) ensures easy cleaning.
• Some systems use SIP (Sterilization-in-Place) for sterile production.
• Compliance with 21 CFR Part 11 (for automated systems) ensures regulatory adherence.
