Sterile Ampoule Washing Machine

A Sterile Ampoule Washing Machine is specialized equipment used in pharmaceutical, biotechnology, and related industries to clean and sterilize ampoules (small sealed glass or plastic vials) before they are filled with injectable drugs, vaccines, or other sensitive products. These machines ensure the ampoules are free from contaminants such as dust, particles, microbes, and endotoxins, maintaining the sterility and safety required for pharmaceutical production.

The primary objective of a sterile ampoule washing machine is to remove impurities, particulate matter, and microorganisms from both the internal and external surfaces of ampoules. This ensures compliance with stringent regulatory standards, such as current Good Manufacturing Practices (cGMP) and FDA guidelines, preventing contamination of the final product and ensuring patient safety.

Working Principle

1. Loading: Ampoules are manually or automatically loaded onto an in-feed tray or conveyor, often via a turntable or star wheel.

2. Transport: A gripper system or conveyor (rotary or linear) transports ampoules through cleaning stations, often inverting them for internal washing.

3. Washing Cycle: Ampoules undergo a sequence of cleaning steps, typically including:

   • Internal and External Wash: High-pressure jets of recycled water, purified water, or WFI clean both surfaces.

   • Compressed Air Blow: Removes water and debris with filtered air.

   • Final WFI Rinse: Ensures sterility with Water for Injection.

   • Drying: Filtered air dries the ampoules to remove residual moisture.

4. Discharge: Cleaned ampoules are released to an out-feed system (e.g., conveyor or tray) for sterilization, filling, or further processing under laminar airflow to maintain sterility.

Typical Washing Cycle Example

• Station 1: Internal and external wash with recycled water.

• Station 2: Internal blow with compressed air.

• Station 3: Internal wash with purified water.

• Station 4: Internal blow with compressed air.

• Station 5: Internal wash with WFI.

• Station 6: Internal and external drying with compressed air.

Process Operation of Ampoule Washing Machine

Ampoules feed from the Infeed tray are received on an Infeed Feed worm then moves on Infeed starwheel. The Grippers picks up the Ampoule from Infeed Star Wheel and invert it in neck down position over washing needles and move along with the needle bar for Washing. Ampoules traveling in neck down position above washing needles and moves along with the Needle bar ensures maximum time for washing once the needle enter in the Ampoule neck. Machine having six different washing stations each of 6 needles for optimum Washing and the sequence can be adjusted as per requirements. Washer also having external wash for optimum washing of ampoules.

On completion of a cycle, washed Ampoules are again inverted to neck upward position and feed to output star wheel. Washed Ampoules received from output starwheel can be collected on Output Tray or can be pushed to tunnel. A separate pumping station (optional) gives the right quantum of water at the desired pressure. In the absent of separate pumping station, we can provide the re-circulation & siliconization system on request.

INTERNAL CLEANING:

The AVRW is equipped with 6 internal cleaning stations and each station has 6 cleaning needles making up a total of 36 cleaning needles. Each cleaning station is supplied via a pipe connected to the cleaning media-making washing area. This not only reduces the risk of particle generation, but also simplifies maintenance and cleaning efforts while saving time.

EXTERNAL CLEANING

The 3 external cleaning stations mounted in a stationary position above the ampoule can be easily adjusted for a specific height, angle and lateral position. Each cleaning station receives cleaning media-making through a pipe connected to the cleaning media-making washing area.

CLEANING MEDIA PRINCIPAL:

WFI, Purified water and air cleaning station are synchronized with the ampoule by reciprocating motion. Design is such that these media are put to use only when needles motion in forward direction. WFI consumption is further reduced by collecting the WFI in re-circulating water tank to be used later on in the pre-washing station.
