The Liquid Nitrogen Dosing Machine is an advanced and essential piece of equipment used in various industries, particularly in food and beverage packaging. This machine ensures that products are sealed with minimal oxygen content, thereby extending shelf life and maintaining product freshness.

The Liquid Nitrogen Dosing Machine operates by injecting a precise amount of liquid nitrogen dosing into each container just before sealing. As the liquid nitrogen evaporates, it displaces the oxygen inside the container, creating an inert atmosphere. This process is crucial for preventing oxidation, which can deteriorate the quality and taste of the product. Additionally, the slight pressurization from the evaporating nitrogen helps maintain the structural integrity of the container, which is particularly important for carbonated beverages.

Performance-wise, the Liquid Nitrogen Dosing Machine is known for its accuracy and reliability. It is equipped with state-of-the-art sensors and control systems that ensure consistent liquid nitrogen dosing for every cycle, regardless of the speed of the production line. This precision reduces waste and ensures that each product is packaged under optimal conditions, preserving its quality over time.

The nitrogen dosing machine is also highly versatile, capable of handling different container sizes and types, making it suitable for a wide range of packaging applications. Its ability to integrate seamlessly into existing production lines further enhances its value, offering manufacturers a reliable solution for enhancing product longevity and quality.

In summary, the Liquid Nitrogen Dosing Machine is a critical asset for modern packaging operations, delivering precise liquid nitrogen dosing to ensure products are protected from oxidation and maintained in peak condition. The nitrogen dosing machine offers unmatched performance in terms of accuracy, speed, and adaptability, making it indispensable in industries where product preservation is a priority.

WYD-600 Liquid Nitrogen Dosing Machine is the latest liquid nitrogen dosing machine in China which uses the similar machines abroad for reference. It could control dosing volume accurately, no-container-no-liquid dosing, small size, easy installation and could coordinate with any filling production line. Control system comprises Siemens PLC and touch screen, all pipes adopt vacuum heat-insulated pipes which could ensure minimum consumption of liquid nitrogen and no frosting operation condition.


How does liquid nitrogen doser working process
Liquid nitrogen gasify and volume expansion 700 times, extrude the air out and form vacuum in the can, increase the aluminum can/pet can internal pressure to prolong the canned beverage shelf life and keep good looking for better transportation and store.


Nitrogen Dosing in PET Bottles: By injecting nitrogen into PET bottles, the internal pressure is increased, oxygen is removed, and the weight of the bottle is reduced, allowing for the use of lightweight bottles.


Vacuum Insulation: The system maintains a vacuum (less than 1×10⁻⁵ mbar) with insulation to achieve ultra-low daily evaporation rates, thereby reducing operating costs.


Nozzle Blanketing System: The nozzle is protected with dry nitrogen under positive pressure to prevent external air from entering, which can cause frost formation and blockages inside the nozzle. This setup ensures the nozzle remains ice-free and maintains a stable flow and direction of liquid nitrogen, unaffected by the positive pressure in the cleanroom or airflow generated by high-speed filling and sealing.


Liquid Level Control: The liquid nitrogen level is controlled by level probes and a vacuum pneumatic cryogenic proportional valve, ensuring stable levels and improving dosing accuracy.


Automatic Adjustment: The system automatically compensates the dosing amount (valve opening percentage) based on the filling and capping machine's speed, according to preset programs.
Soft Dosing Technology: This technology prevents rebound, splashing, evaporation, and boiling of liquid nitrogen during dosing, reducing liquid nitrogen loss and the occurrence of high-pressure and low-pressure products, thus saving costs.
Bilingual Interface: The system supports Chinese and English languages, allowing for easy switching between them.



Gas-Liquid Separator: It maintains pure liquid nitrogen at the outlet.


Speed and Position Tracking: The system can automatically track the speed and position of the filling and capping machine.

Communication Function: It can communicate with the filling and sealing machine.

Automatic Flow Adjustment: When speed changes occur, the dosing flow rate automatically adjusts. The adjustment of the flow rate, which corresponds to the valve opening percentage, switches automatically according to preset menus. This ensures consistent dosing amounts at different speeds, maintaining uniform product pressure.



Advanced Liquid Inlet Valve Design: The system features a scientifically advanced liquid inlet valve design with bellows compensators and gas seals, extending the machine's lifespan.


Unique Valve Needle Design: A unique valve needle design with a pressure-reducing device minimizes dosing pressure.

Minimal Wear Parts: The valve needle has a lifespan of over 10 years without needing replacement.
