NovoDoser Advanced Nozzle Blanketing Tech
29 December 2024
In the world of LN2 dosing systems, precision and efficiency are paramount. However, one persistent challenge faced by manufacturers is nozzle frosting, which can disrupt dosing accuracy, higher production downtime, and compromise product quality. Traditional systems attempt to address this issue with external nitrogen gas for nozzle blanketing, but this approach adds complexity and inconsistency. NovoDoser, provides a revolutionary solution equipped with a self-generating nozzle blanketing feature that simplifies operations and ensures flawless performance.
Nozzle blanketing is a technique that prevents frosting on the dosing nozzle by maintaining a protective nitrogen gas layer around it. For this technique to work properly, the nitrogen gas must be pure with extremely low dew point, creating a barrier at a pressure slightly higher than atmospheric pressure, effectively blocking moisture-laden air from coming into contact with the nozzle during both dosing and standby modes.
Why is this important?
Frost formation on the nozzle can:
- Block LN2 flow, causing dosing inconsistencies.
- Lead to production downtime and reduced efficiency.
- Result in higher maintenance cost.
Traditional dosing systems that offer nozzle blanketing rely on external nitrogen gas sources, introducing several drawbacks:
- System Complexity:
- External gas requires additional pressure control circuits, increasing system size and maintenance needs.
- Inconsistent Pressure
- Variations in external gas pressure can compromise the effectiveness of the blanketing function.
- Higher Moisture Contamination
- Decreases nozzle blanketing performance and higher risk of frosting
- Higher Operating Costs
- Continuous reliance on external nitrogen gas increases operational expenses.
The NovoDoser LN2 Dosing System eliminates these challenges with its self-generating nitrogen gas blanketing technology. By leveraging a small, controlled volume of liquid nitrogen (LN2) from its internal reservoir, NovoDoser produces the necessary nitrogen gas at -196 deg C dew point with moisture content below one-thousandth of a ppb to create a consistent and effective nozzle blanket.
- A controlled amount of LN2 is evaporated from the NovoDoser reservoir.
- The evaporated nitrogen gas is delivered to the nozzle area at a slightly higher pressure than atmospheric pressure.
- This gas layer act as barrier to atmospheric moisture from reaching the cold nozzle surface, eliminating frost formation during both dosing and standby modes.
- Simplified System Design
- NovoDoser eliminates the need for external nitrogen gas sources and complex pressure control circuits.
- The self-generating nitrogen system is fully integrated, reducing installation and operational complexity.
- Consistent and Reliable Performance
- By utilizing internal LN2 for nitrogen generation, NovoDoser ensures a moisture free, steady and controlled gas pressure.
- This consistency enhances the blanketing function, keeping the nozzle frost-free in all operating conditions.
- Reduced downtime and Maintenance Requirements
- Reduce production downtime and frequent machine shut down for nozzle defrosting tasks
- This leads to lower maintenance costs and longer equipment lifespan.
- Enhanced Dosing Accuracy
- With no frost to interfere with LN2 flow, dosing volumes remain precise and consistent.
- This improves product quality and reduces wastage, particularly in high-speed production lines.
- Improved Energy Efficiency
- The self-generating nitrogen system is powered by existing LN2 reservoir pressure and heat from the natural environment
- Thus, eliminates the need for additional gas supply infrastructure and energy consumption.
- Cost Savings
- No need to purchase external nitrogen gas or invest in additional pressure control systems.
- Reduced downtime and maintenance further optimize overall operational cost
NovoDoser’s nozzle blanketing feature is ideal for industries where LN2 dosing accuracy and reliability are critical:
