Liquid Nitrogen Filling Machine
Cassman
Our Liquid Nitrogen Dosing System is an advanced engineering solution designed to harness the power of cryogenics for superior packaging. By accurately dosing liquid nitrogen, which instantly converts to gas, the system provides the precise internal pressure required for a wide range of applications—from strengthening lightweight PET bottles to displacing oxygen in sensitive products.
The process is seamless and fully automated. LN2 is transferred from a main storage tank through a vacuum-insulated pipe to the doser's integrated reservoir. Here, an advanced gas-liquid separator purifies the nitrogen before it is delivered to the dosing head. Using container presence and line speed sensors, our speed-synchronized dosing technology ensures that every container receives the exact same dose, every time. The entire process is managed by a sophisticated control system integrating a PLC, sensors, and a user-friendly HMI.
Our system adapts to your specific production needs with several intelligent dosing modes:
Adaptive Dosing Mode: The most efficient mode for variable lines. An integrated sensor detects each container, dosing on a "one can, one dose" basis. No container, no dose—eliminating waste.
Fixed Speed Mode: The machine operates at a constant, pre-set dosing speed, ideal for consistent production runs.
Continuous Dosing Mode: For the highest throughput demands, the dosing head remains open, capable of reaching speeds up to 2,000 containers per minute.
User-Defined Switching: You can set a specific line speed at which the system automatically transitions between adaptive and continuous modes for optimized performance.
| Feature | Benefit |
|---|---|
| Positive Pressure Nozzle Protection | Dry nitrogen gas creates a protective barrier around the nozzle, preventing ambient moisture from causing frost and ice blockages, ensuring uninterrupted operation. |
| High-Precision Level Control | A differential pressure gauge and integrated gas-liquid separator provide highly accurate liquid level monitoring, enabling pressureless dosing for maximum stability. |
| Advanced Vacuum Insulation | Utilizes state-of-the-art insulation technology to minimize LN2 evaporation, significantly reducing operational costs and maximizing efficiency. |
| Micro-Dosing Technology | Delivers exceptional dosing consistency and accuracy across all production speeds, from crawl to max, ensuring uniform results for every container. |
| "Soft Dosing" Compatibility | The gentle dosing process is perfectly suited for delicate applications, including hot-fill products, powders, and granulated goods. |
| Intelligent Remote System | Enables remote monitoring and troubleshooting capabilities, helping to reduce or eliminate system downtime by providing real-time diagnostics. |
| Automated Level Control | The system automatically maintains the LN2 level within a user-defined range, ensuring a stable supply for the dosing head without manual intervention. |
| Compact Footprint | Thoughtfully designed to be compact, allowing for easy integration and installation even in packaging lines with limited space. |
Whether you're looking to lightweight your containers, eliminate paneling, or extend the shelf life of your products, our Liquid Nitrogen Dosing System offers the precision, reliability, and efficiency you need.
