The aseptic liquid nitrogen dosing machine is an advanced system designed to handle liquid nitrogen dosing with exceptional precision and efficiency, particularly in sterile environments. This machine is crucial for industries where maintaining the highest hygiene standards and extending product shelf life are vital, such as in the food, beverage, and pharmaceutical sectors.
The performance of the aseptic liquid nitrogen dosing machine is characterized by its ability to accurately dispense liquid nitrogen into containers before they are sealed. This precise liquid nitrogen dosing is essential for creating a nitrogen-rich atmosphere within the container, which helps to preserve the freshness and quality of the product. The machine's advanced control systems and sensors ensure that each dose of liquid nitrogen is consistent, minimizing the risk of spoilage and oxidation.
Operating under sterile conditions, the liquid nitrogen dosing machine prevents contamination and maintains the aseptic environment required for sensitive products. By integrating liquid nitrogen dosing with aseptic technology, this machine ensures that the product remains uncontaminated and safe for consumption. This is particularly important for products that do not contain preservatives or those that require stringent safety standards.
In addition to its dosing capabilities, the aseptic liquid nitrogen dosing machine contributes to the structural integrity of the packaging. By creating a slight positive pressure inside the container, the machine prevents collapse or deformation, which is crucial for maintaining the quality and appearance of lightweight or flexible packaging materials.
Overall, the aseptic liquid nitrogen dosing machine offers a high level of precision and efficiency in the liquid nitrogen dosing process. Its ability to operate in sterile conditions and maintain packaging integrity makes it a valuable asset for manufacturers seeking to enhance product quality and extend shelf life while meeting rigorous safety standards. Investing in this technology can significantly improve production processes and ensure that products are delivered to consumers in optimal condition.
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.
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.
