In the high-stakes environment of injectable drug production, the integrity of the primary packaging container is the first line of defense against pyrogens and particulate matter. As biopharmaceuticals and advanced formulations move toward higher potency and lower batch volumes, the demand for absolute sterility in tubular vials has shifted from a general requirement to a precision engineering challenge.
Jiangsu Pharmasys Intelligent Equipment Co., Ltd. addresses this critical need through the QXP-XA Vertical Ultrasonic Washer. By integrating a sophisticated "Water-Air Alternating Rinsing" protocol within a vertical rotary drum architecture, Pharmasys provides a solution that transcends traditional cleaning methods.
The Engineering Logic of Independent Medium Circuits
The core of the Pharmasys cleaning philosophy is the total isolation of cleaning media. Traditional washing systems often suffer from "media drag-over," where residual water or air from one cycle contaminates the next.
The QXP-XA system is engineered with an independent piping system where WFI (Water for Injection) and sterile compressed air operate on segregated circuits. This architectural choice ensures that:
-
Cross-Contamination is Physically Impossible: Each cleaning medium has its own dedicated nozzle path and valve control.
-
Mechanical Scouring is Maximized: The alternating sequence creates a "pulsing" effect. The water dislodges particles via ultrasonic cavitation, while the high-pressure air blast clears the internal geometry, ensuring no stagnant film remains on the inner walls.

Technical Configuration of the QXP-XA Vertical System
| Feature | Specification / Benefit |
| Machine Material | Full SS 304 Stainless Steel (External & Contact Parts) |
| Drum Design | Three-dimensional vertical rotary drum (Space-saving) |
| Washing Logic | Alternating Water-Air-Water-Air Sequence |
| Vial Compatibility | Optimized for Tubular Vials (2ml - 100ml) |
| Transmission | Low-friction smooth operation (Reduced Maintenance) |
| Control System | Integrated Electrical Control with Circulating Water Logic |
Overcoming the "Shadow Zone" in Tubular Vial Cleaning
Tubular vials, particularly those used in medical aesthetics and biopharma, often have narrow necks and specific shoulder geometries that create "shadow zones"—areas where standard spray nozzles fail to reach.
Pharmasys solves this through Vertical Ultrasonic Cavitation. As the vials pass through the ultrasonic tank in the rotary drum, high-frequency sound waves create millions of microscopic bubbles. When these bubbles implode, they release energy that strips away sub-micron particles. The subsequent Water-Air Alternating Rinsing then flushes these loosened particles out. Without the "air pulse" following the "water wash," surface tension often keeps particulates trapped in the fluid film inside the vial.
Space Efficiency and Aseptic Layout Integration
Modern aseptic filling lines are frequently constrained by cleanroom square footage. The QXP-XA is designed with a rationally and compactly arranged footprint.
Unlike horizontal washers that require extensive linear space, the three-dimensional rotary drum design utilizes verticality. This allows pharmaceutical enterprises to integrate a full-scale ultrasonic washing, drying, and sterilizing tunnel within a significantly smaller footprint, reducing the overall CAPEX and OPEX associated with cleanroom maintenance.
Industry Standards and Compliance Data
According to recent PDA (Parenteral Drug Association) technical reports, over 60% of particulate contamination in injectables originates from inadequate primary container preparation. The WHO TRS 961 Annex 6 specifically emphasizes the need for validated cleaning processes that eliminate "dead legs" in piping.
Pharmasys equipment is built to exceed these global benchmarks:
-
SS 304 Construction: Ensures chemical resistance and ease of sanitization, preventing microbial biofilm buildup.
-
Independent Outfeed Systems: Prevents the re-contamination of clean vials as they transition to the sterilizing tunnel.
-
Reduced Maintenance Transmission: By utilizing high-precision machining centers in the manufacturing of the QXP-XA, Pharmasys ensures that transmission components operate smoothly, reducing the shedding of metallic micro-particles during operation.
Multi-Stage Rinsing: A Step-by-Step Breakdown
The Pharmasys washing cycle is a symphony of fluid dynamics and ultrasonic power:
-
Ultrasonic Pre-wash: Vials are submerged to loosen heavy debris.
-
Internal/External Water Rinsing: Independent nozzles target the inner and outer walls simultaneously.
-
High-Pressure Air Purge: Sterile air breaks the surface tension and removes residual water.
-
Final WFI Rinse: Ensures the vial meets the conductivity and TOC requirements of the USP/EP.
-
Final Air Dry: Prepares the vial for the heat-intensive sterilizing tunnel.
FAQ: Addressing Common Technical Inquiries
How does the QXP-XA prevent vials from breaking during high-speed rotation?
The machine uses a precision-engineered transmission system and smooth-surface rotary drum components. This reduces mechanical stress and glass-to-metal impact, which is crucial for thin-walled tubular vials.
Can the washing parameters be customized for different vial sizes?
Yes. The integrated electrical control system allows for the adjustment of rinsing pressures and ultrasonic frequencies, accommodating various vial specifications common in medical aesthetics and advanced formulations.
Why is SS 304 used instead of standard plastics for the exterior?
Aseptic environments require rigorous cleaning with vaporized hydrogen peroxide (VHP) or other disinfectants. SS 304 provides the necessary corrosion resistance to maintain a sterile exterior surface over years of operation.
