Working Principle of Pharmaceutical Ampoule Washer

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.

Benefits of Pharmaceutical Ampoule Washer

Ensures Highest Level of Cleanliness and Sterility

The machine delivers thorough internal and external cleaning using 6 washing stations with 36 needles and a programmable 3 water + 3 air wash cycle (Recycled WFI → Air → DM Water → Air → Fresh WFI → Air). This effectively removes dust, particles, fibers, residues, and endotoxins, ensuring ampoules meet the strict sterility requirements for injectable drugs, vaccines, and sterile liquids. It significantly reduces the risk of product contamination and batch rejection.

High Production Speed and Efficiency

With output ranging from 100 to 200 ampoules per minute (depending on model), the rotary design supports continuous, high-volume production without frequent stops. It integrates easily into complete injectable lines (washing → filling → sealing), boosting overall plant productivity and reducing labor dependency compared to manual or semi-automatic washing methods.

Superior Contamination Control with Advanced Design

The neck-gripping and inversion system holds ampoules by the neck (neck-down position) during washing, minimizing surface contact and particle generation. Independent circuits for each washing zone, “No Container – No Wash” feature, and advanced filtration prevent cross-contamination. Acrylic safety covers with interlocks further protect the sterile environment, making it highly suitable for aseptic manufacturing.

Gentle Handling and Minimal Breakage

The precise starwheel, feed worm, and gripper mechanism handles fragile glass ampoules (1ml to 10ml) very gently, resulting in an extremely low breakage rate (typically < 0.5%). Quick-change parts allow fast size changeover, reducing downtime and glass waste while offering flexibility for different batch sizes and multi-product production.

Resource Efficiency and Cost Savings

Water recirculation system reuses WFI for initial washes, significantly lowering consumption of expensive Water for Injection.
