Automatic Linear Vial Washer

High-Throughput Linear Decontamination for Pharmaceutical Glassware

In sterile pharmaceutical manufacturing, the integrity of primary packaging is paramount. Harsiddh Unimach Pvt. Ltd. delivers an industry-leading solution with our Automatic Linear Vial Washing Machine. Engineered to meet the stringent regulatory standards of the global healthcare, biotech, and cosmetic industries, this CE-certified equipment maximizes cleaning throughput while ensuring absolute contamination control.

By eliminating intensive manual handling and substituting it with high-speed, automated linear processing, our system provides repeatable, validated cleaning cycles. Whether you are processing small-batch clinical trials or running continuous high-volume production lines, this machine offers the ultimate combination of structural reliability, aseptic safety, and operational flexibility.

Advanced Engineering & Operational Principle

The core of our linear vial washer lies in its sophisticated mechanical handling. The equipment features a meticulously engineered in-feed worm wheel mechanism that receives vials from the upstream conveyor line. As the vials advance, the system gently and securely inverts them by 180 degrees. This precise inversion positions the mouth of each vial directly above the high-pressure washing nozzles.

Holding the vials firmly in place prevents glass-to-glass friction, drastically reducing the risk of hairline cracks, breakage, or cosmetic scratches. Once inverted, the vials travel through a series of dedicated decontamination zones where high-velocity fluid and air streams thoroughly purge internal and external surfaces of all particulate matter. After completing the customized washing cycles, the system smoothly re-inverts the vials back to their upright position, discharging them directly onto the exit conveyor line or into a sterilizing tunnel.

Comprehensive 7-Stage Validated Washing Sequence

To guarantee a completely sterile container surface, the Automatic Linear Vial Washer is built to perform a rigorous, standard 7-Stage Washing Sequence. This sequence can be tailored and customized to match specific regulatory standard operating procedures (SOPs) and your specific container materials.

The decontamination cycle relies on a balance of internal and external flushes divided into water and air phases:

Phase 1: High-Pressure Water Cleansing (4 Stages)

The system utilizes four distinct water washes to dissolve chemical residues, lift adherent particulates, and rinse away contaminants.

1. Recycled Water / Fresh Water Flush: Initial external and internal rinse to dislodge heavy physical particles.
2. Purified / Demineralized (DM) Water Flush: Deep cleansing stage to eliminate mineral deposits and chemical residues.
3. Second Demineralized Water Rinse: Ensures no trace elements remain from the initial cycles.
4. Water for Injection (WFI) Flush: The final critical rinse using ultra-pure WFI to meet international injectable standards.

Phase 2: High-Velocity Air Decontamination (3 Stages)

Between and after the water washes, the machine executes three high-velocity air flushes using compressed, sterile air.

5. Intermittent Air Blast: Clears out heavy water pockets between fluid shifts to prevent cross-contamination.
6. Internal Air Evacuation: High-pressure air jets penetrate deep inside the vial to shear remaining moisture droplets off internal walls.
7. Final Air Purge: Prepares the vials for downstream drying, sterilization, or immediate aseptic filling by leaving them virtually free of liquid residues.

Total Cross-Contamination Prevention

A standout feature of the design by Harsiddh Unimach Pvt. Ltd. is the incorporation of Independent Fluid Circuits. Each washing zone operates via its own dedicated pumping system and manifold line. This strictly segregated architecture eliminates fluid mixing or cross-contamination between the initial recycled water stages and the final pure WFI stage.

Key Technical Features & Benefits

• Maximum Aseptic Security: With fully automated in-feed, cleaning, inversion, and out-feed processing, manual human intervention is entirely removed from the washing zone. This significantly reduces micro-organism and airborne particulate exposure.
• Broad Container Flexibility: The machine handles a versatile range of glass and molded vials, seamlessly accommodating sizes from small 2ml vials up to large 30ml containers.
• Tool-Less, Quick Changeover: Time is a critical metric in pharmaceutical manufacturing. Our linear washer features a highly accessible design where the input/exit feed worms, star wheels, and guide rails can be swapped out quickly with minimal tools. This significantly cuts down line downtime when switching between different vial dimensions.
• Resource-Efficient Engineering: Sustainability meets cost savings. The system is designed with low water and electricity consumption ratios. Optional water recycling systems can catch, filter, and reuse water from advanced stages in the initial pre-wash phases, drastically lowering overall operational utility costs.
• Robust, GMP-Compliant Construction: All contact parts are fabricated from superior-grade AISI 316L stainless steel, while non-contact structures utilize AISI 304 stainless steel. Smooth surface finishes, polished welds, and the absence of dead legs prevent bacterial growth and simplify the cleaning-in-place (CIP) process.

Custom Optional Enhancements

To cater to specialized drug delivery requirements, Harsiddh Unimach Pvt. Ltd. offers seamless integration of advanced optional features:

• Integrated Siliconization System: For highly sensitive biological products or viscous formulations where fluid retention on glass walls must be minimized, the machine can be adapted with a precise siliconization module. This coats the inner walls of the vials uniformly during the washing cycle.
• PLC and HMI Automation Touchscreen: Upgrade to a fully automated PLC system with an intuitive human-machine interface (HMI). This allows production supervisors to store multiple washing recipes, monitor real-time pressure diagnostics, and track cycle logs for compliance.
