Product Description

Liquid Nitrogen Doser 

Liquid Nitrogen Doser/TB- COCO2

Introducing a cutting-edge

Liquid Nitrogen DoserTB- COCO2, packed with most advance dosing control technology, ensuring frost-free operation. Crafted from food-grade authenticate stainless steel, this doser boasts a hygienic wash-down design, fully compliant with rigorous HACCP requirements. Designed for high speed aluminum can lines and lightweight PET bottling lines.

Key Features:

Servo-operated Dosing Valve: Coupled with enhanced dose pressure capability, ensuring precise dosing on high-speed bottling line with small mouth opening

Extended and Flexible Arm:  Allows for close-proximity dosing just before capping, reducing LN2 usage while maintaining consistent pressure between bottles.

Variable Dose Pressure: TB- COCO2 offers flexible liquid head pressure, making dosing pressure control a breeze and easily adaptable to your specific filling process requirements. It’s suitable for both hot and cold filling processes.

Ultra Precision Dosing: Incorporates a subcooling function, guaranteeing constant liquid nitrogen density for ultra-precise dose mass.

Nozzle or System Quick-Defrost: Equipped with an efficient purging system that employs warm gas nitrogen for quick and thorough nozzle or system defrosting. It’s user-friendly and ensures minimal downtime.

Innovative Dosing Solution:

With TB- COCO2, you can expect precise dosing and enhanced operational efficiency in your liquid nitrogen dosing processes.

1. Interval filling method without tank or filling at low speed to reduce liquid nitrogen loss and operating costs. The filling valve is always open at high speed and automatically detects high and low speeds.

2. Vacuum insulation protection to reduce operating costs.

3. The special nozzle care system effectively prevents frost and ice blockage in the nozzle.

4. Liquid-gas separator ensures that liquid nitrogen is in a super-cooled state, improving liquid phase purity and making filling more accurate and stable.

5. The liquid nitrogen buffer function effectively controls the rebound and splashing of liquid nitrogen, and the liquid nitrogen filling amount is stable to ensure balanced tank pressure.

6. Equipped with 10 micron filter to remove particulate pollution.

7. The filling speed of liquid nitrogen can be as high as 800 tanks/minute, and when the speed is greater than 800 tanks/minute, it is continuous filling.

8. The adjustability of multiple filling speeds and the efficient vacuum liquid nitrogen insulated pipeline ensure the minimum liquid nitrogen consumption.

9. The advanced nature of the filling valve ensures that pure and single-phase liquid nitrogen can be transported.

10. The lowest outlet pressure of the filling valve ensures the minimization of liquid nitrogen splash.

11. Frost-free operating environment.

12. Precise adjustability of filling amount and filling time during operation.

13. The system can be continuously self-monitored through the alarm indicator.

14. PLC control/touch screen/user interface language optional.

15. It can be directly connected to the liquid nitrogen vacuum insulated pipeline, and can provide a complete liquid nitrogen supply system from the liquid nitrogen storage tank to the filling line.

16. The compact appearance and simple installation are suitable for any filling line.

17. The diversity of machine models ensures that it can match the speed and application of any assembly line.

18. Applicable to all PET bottles and thin-walled cans production lines.
