Linear Vial Washing Machine

A Linear Vial Washing Machine is a specialized, fully automated piece of equipment primarily used in the pharmaceutical, biotechnology, and healthcare industries for cleaning and rinsing glass vials before they are filled with sterile products such as injectables, vaccines, or oral liquids. It operates on a linear conveyor system (often in a tunnel-type configuration), where vials are fed in a straight-line path through multiple washing stations. This design ensures thorough removal of contaminants, particles, and residues from both the interior and exterior surfaces of vials, meeting stringent GMP (Good Manufacturing Practice) and cGMP standards for sterility and quality control.

Key Features

• Construction: Built with high-grade stainless steel for corrosion resistance, durability, and easy cleaning. The structure is vibration-free and rigid, often enclosed with safety acrylic doors for operator protection.

• Feeding and Handling: Vials are loaded via an in-feed turntable or conveyor. An automatic loading mechanism orients vials mouth-down into SS wire mesh pockets or conveyor belts, minimizing manual intervention and saving manpower.

• Washing Process: Equipped with 5–8 washing stations/zones, including:

  • High-pressure jets/nozzles for internal and external cleaning.

  • Interchangeable cycles: Compressed air (for drying), re-circulated or fresh DM (demineralized) water, and WFI (Water for Injection) for rinsing.

  • Typical sequence: Initial air purge, followed by water rinses (e.g., 4 water washes and 3 air washes), with nozzles entering the vial neck for complete coverage.

  • Water recycling systems for efficiency and resource conservation.

• Output and Speed: Capable of processing 100–240 vials per minute, depending on the model, with flexibility for size changes via minimal format parts.

• Controls and Safety: Electrically controlled via magnetic valves, PLC (Programmable Logic Controller), HMI (Human-Machine Interface), and AC drives for precise spray duration and sequence. Includes emergency stops, safety clutches for jammed vials, and smooth, noiseless operation.

• Integration: Easily connects to downstream equipment like sterilizing tunnels, filling lines, or out-feed turntables for seamless production lines.

Applications

Ideal for high-speed, sterile vial preparation in pharmaceutical manufacturing. It handles round or flat vials efficiently and supports customization for specific wash media (e.g., fresh water, DM water, or WFI). Models like tunnel-type variants enhance isolation for aseptic environments.

Process Operation of Linear Vial Washer Machine

Containers feed from the de-cartooning station are received on an Infeed turn table through visual inspection unit. An in feed worm inverts container to neck down position and feeds them through a specially designed indexing device. The device carries the container forward and stops. Nozzles carrier enters into the container and activities the jet of water/air. The air/water flow is deactivated after the washing cycle is over. Device indexes the vials for next wash. A separate pumping station gives the right quantum of water at the desired pressure. Washed containers are again inverted to neck upward position to collect in trays or directly feed to sterilizing tunnel.
