Automatic Linear Tunnel Type Vial Washing Machine

Advanced Continuous Decontamination

In high-speed pharmaceutical manufacturing, maintaining sterile integrity begins long before the first drop of liquid enters a container. Contaminants, microscopic debris, and glass particulates present a constant risk to product safety and regulatory compliance. The Automatic Linear Tunnel Type Vial Washing Machine by Harsiddh Unimach Pvt. Ltd. is engineered to serve as the critical first line of defense in your sterile processing line. Designed for seamless, continuous decontamination of glass vials, this high-performance machinery guarantees that every container is meticulously cleaned, validated, and ready for aseptic filling.

With a robust linear architecture, advanced multi-stage wash customization, and strict adherence to global pharmaceutical standards, this machine delivers the ultimate combination of operational precision, compact efficiency, and flexible throughput.

The Core Concept: Advanced Continuous Decontamination

The primary objective of the Linear Tunnel Type Vial Washing Machine is to eliminate any risk of cross-contamination while maximizing production uptime. Traditional batch washing methods introduce variables and manual handling risks; our linear tunnel system completely automates the process from in-feed to discharge.

Engineered specifically for the demands of modern injectable production, this equipment effortlessly handles glass vials ranging from 2ml to 30ml. By utilizing a sophisticated linear track system, it maintains uniform speed, controlled movement, and synchronized handling. This continuous flow design allows the washer to be installed directly inline with sterilizing tunnels, liquid fillers, and capping machinery, forming an uninterrupted, high-efficiency production ecosystem.

As a CE-certified solution, it meets rigorous international safety, environmental, and quality standards, making it a reliable asset for pharmaceutical companies targeting both domestic and global export markets.

Operational Precision & Step-by-Step Cleaning Sequence

The true value of our linear vial washer lies in its mechanical precision. The machine transforms a bulk collection of unwashed vials into a perfectly organized, individually sanitized stream of containers through a highly organized, automated process.

1. Automated Loading and In-feed Tracking

The cycle begins at the high-capacity, integrated round turn table. Unwashed vials are loaded onto the rotary platform, which gently guides and pushes them into a steady, mechanized conveyor feed system. Depending on your production volume requirements, the machine utilizes a single-track or double-track conveyor system to transition the vials smoothly into the main washing tunnel without glass-to-glass scuffing or tipping.

2. Secure Clamping and Inversion

To achieve deep, comprehensive cleaning, vials must be washed from the inside out. As the containers enter the washing zone, custom-designed grippers securely clamp each vial by its neck. The mechanical indexing mechanism then smoothly inverts the vials by 180 degrees, positioning the openings downward directly over the high-pressure spray nozzles. This orientation ensures that all dislodged particulates and wash fluids drain instantly via gravity, preventing contaminated water from pooling inside the container.

3. Multi-Zone Internal and External Washing

Once inverted, the vials travel continuously through a series of dedicated, internal and external washing stations. The washing zone architecture is highly advanced:

• Independent Circuits: The system is divided into five completely independent washing zones. Each zone operates on its own isolated fluid circuit, eliminating the possibility of used water from an early cycle mixing with the pristine water of a later stage.
• High-Density Spray Jets: Micro-nozzles deliver concentrated, high-pressure streams directly into the core of the vials. Simultaneously, external spray headers shower the outside surfaces, removing external dust and debris.
• Customizable Washing Media: The sequence of the cleaning media can be entirely tailored to match your facility’s internal Standard Operating Procedures (SOPs). A standard, highly effective configuration includes:
  1. Fresh Water Wash: Initial rinse to dislodge large particulate matter.
  2. Deionized (DI) / Demineralized (DM) Water Wash: Removes chemical residues and mineral trace elements.
  3. Water for Injection (WFI) Rinse: A final, critical rinse utilizing sterile WFI to ensure biological and chemical purity.
  4. Compressed Air Purge: High-pressure, oil-free compressed air blows out remaining moisture, preparing the vials for the heat sterilization phase.

4. Re-Inversion and Inline Exit

Following the final air blow, the mechanical arms gently rotate the vials another 180 degrees back to their upright position. The clean, decontaminated containers are released onto the out-feed conveyor belt, exiting the machine automatically. From here, they flow directly into the next phase of the production line—typically a sterile depyrogenation tunnel—without any manual intervention or exposure to external environmental hazards.

Key Technical Features & Manufacturing Excellence

Every component of the Automatic Linear Tunnel Type Vial Washing Machine by Harsiddh Unimach Pvt. Ltd. is selected to enhance durability, maintain hygiene, and reduce operational costs.

• Hands-Free, Fully Automated Operation: From the moment unwashed vials are placed on the turn table to their exit onto the downstream line, the process is fully automated. This hands-free workflow reduces human intervention, which is statistically the largest source of contamination in pharmaceutical environments.
• Premium Material Construction: In compliance with cGMP expectations, the main structural frame, covers, and non-contact components are fabricated from high-grade Stainless Steel 304 (SS304). Every single component that comes into direct contact with the washing media or the vials—including spray nozzles, fluid manifolds, clamps, and internal piping—is crafted from premium Stainless Steel 316L (SS316L) to prevent corrosion and ensure maximum chemical compatibility.
• Vibration-Free, High-Speed Performance: Industrial washers can experience wear due to the constant motion of high-pressure pumps and mechanical conveyors. Our machine features a heavily reinforced structural base that absorbs micro-vibrations. This robust design guarantees smooth, quiet, and stable performance even when running at maximum output speeds.
• Quick, Tool-Less Changeovers: Pharmaceutical facilities frequently switch production between different vial capacities (e.g., transitioning from a 2ml vaccine vial to a 30ml antibiotic vial). Our linear washer minimizes downtime with an intuitive, operator-friendly changeover system. Adjustments for different vial diameters and heights can be completed rapidly, significantly boosting overall equipment effectiveness (OEE).
• Compact Footprint: Despite its comprehensive multi-stage washing capabilities, the linear tunnel layout is space-optimized. It easily integrates into crowded cleanrooms and existing packaging lines without requiring massive structural reconfigurations.
