Q: What is the production capacity of the Tunnel Type Vial Washing Machine?

We offer two standard models: ALVW-80 : 40 to 80 vials per minute ALVW-150 : 80 to 150 vials per minute Higher-speed models are also available based on production requirements.

Q: What vial sizes can the Tunnel Type Vial Washing Machine handle?

The machine can wash vials with diameters from 15mm to 35mm , covering 2ml to 100ml vials. It is suitable for both glass and plastic vials with quick changeover using minimum change parts.

Q: How many washing cycles does the Tunnel Type Vial Washing Machine perform?

It is equipped with 4 Water Washes + 3 Air Washes (total 7 washing stations). Washing nozzles enter inside the vials for thorough internal cleaning. The sequence is fully flexible and user-programmable, typically including DM Water, Purified Water, Water for Injection (WFI), and Compressed Air.

Description

Tunnel Type Vial Washing Machine (also known as an Automatic Linear Tunnel Type Vial Washing Machine) is a specialized, automated piece of equipment primarily used in the pharmaceutical, biotechnology, and injectable drug manufacturing industries. It is designed to thoroughly clean both the internal and external surfaces of glass vials (typically round vials ranging from 2 ml to 100 ml in size) to ensure they are free from contaminants, particles, and residues before filling with sterile products like vaccines, injectables, or medications. This machine operates on a linear conveyor system within a enclosed “tunnel” structure, which maintains separation between the loading (dirty) and unloading (clean) zones to prevent cross-contamination, adhering to cGMP (Current Good Manufacturing Practice) standards.

Working Principle of Tunnel Type Vial Washing 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.

Key Design of Tunnel Type Vial Washing Machine

Tunnel Configuration: Vials are loaded onto a stainless steel (SS) wire mesh conveyor or fed manually via a feed table. They move intermittently through a series of enclosed washing stations inside the tunnel, where high-pressure jets of cleaning agents are applied. The tunnel design ensures a controlled environment, with easy integration to downstream equipment like sterilizing tunnels.

Washing Process:
- Internal Washing: Typically features 8–10 stations using penetrating nozzles that insert into the vial neck for precise cleaning. Common sequences include compressed air (for initial blowing), recirculated water, deionized (DM) water, and fresh Water for Injection (WFI). This ensures deep cleaning without residue.
- External Washing: 2 stations for surface rinsing, often with recirculated water followed by WFI jets.
- Customization: Washing sequences can be modified based on requirements. High-pressure spray nozzles guarantee uniform coverage, and a “no container, no water” system saves resources.

Automation and Controls: Fully automated with PLC and touchscreen HMI (Human-Machine Interface) for interlocks, alarms, and sequence control. Magnetic valves electrically time spray durations. Emergency stops and low-maintenance pumps enhance safety.

Material Construction: Entire frame and contact parts are made from AISI 304/316 stainless steel for corrosion resistance and hygiene. Pipes, tanks, and pumps are also SS 316. No change parts needed for vials 5–30 ml; minimal adjustments for neck size variations.

Loading/Unloading: Automatic loading via conveyor; unloading directly to trays or a turntable. Vibration-free operation for smooth, noiseless performance.
