The Aseptic Liquid Nitrogen Dosing Machine is an advanced piece of equipment designed to enhance the packaging process in industries where sterility and product longevity are critical. This machine integrates the precise technology of a Liquid Nitrogen Dosing Machine with aseptic processing, ensuring that the packaging environment remains sterile throughout the process.

The Aseptic Liquid Nitrogen Dosing Machine works by injecting a controlled amount of liquid nitrogen into each container in a sterile environment. The liquid nitrogen rapidly evaporates, displacing the oxygen and creating an inert atmosphere within the container. This process not only helps in extending the shelf life of the product by preventing oxidation but also maintains the integrity and quality of the contents, which is especially important in the pharmaceutical and food and beverage industries.

Performance-wise, the Aseptic Liquid Nitrogen Dosing Machine is engineered for high precision and consistency. The machine's aseptic design ensures that the nitrogen dosing occurs in a completely sterile environment, which is crucial for products that must remain free from contamination. This machine is also equipped with advanced sensors and control systems that guarantee accurate dosing with each cycle, minimizing waste and ensuring that every package is treated under optimal conditions.

Moreover, the nitrogen dosing machine is versatile and can be easily integrated into existing aseptic production lines. It is designed to handle various container sizes and types, making it suitable for a wide range of applications. The adaptability and precision of this machine make it an invaluable tool for manufacturers aiming to maintain the highest standards of product safety and quality.

In summary, the Aseptic Liquid Nitrogen Dosing Machine combines the benefits of traditional Liquid Nitrogen Dosing Machine technology with the added advantage of aseptic processing. This results in a nitrogen dosing machine that delivers unmatched performance in maintaining product sterility and extending shelf life, making it essential in industries where hygiene and product integrity are paramount.

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.
