Liquid nitrogen dosing and purging machine

FP-N300 Liquid Nitrogen Dosing Machine is the latest liquid nitrogen dosing machine in China which uses similar machines abroad for reference. It could control dosing volume accurately, no-container-no-dosing, small size, easy installation and could coordinate with any filling production line. The Control system comprises Siemens PLC and a touch screen, all pipes adopt vacuum heat-insulated pipes which could ensure mini consumption of liquid nitrogen and no frosting operation condition.

Working Process:

Liquid nitrogen gasify and volume expansion 700 times, extrude the air out and form a 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 storage.

Characteristics:

1、No container no dose and interval dose method in low speed to reduce liquid nitrogen consumption; dosing valve is always open at high speed. Automatic detect high speed or low speed.

2、Vacuum & heat insulation protection

3、Special nozzle care system effectively avoided the nozzle frost and ice blockage phenomenon.

4、liquid-gas separator ensures liquid nitrogen in an ultracold state and improves liquid phase purity to make the dose more precise and steady.

5、Liquid nitrogen buffer function, effectively control liquid nitrogen bounce splash. Liquid nitrogen dosing amount is steady and ensures can pressure equality.

6、Filter(optional) 10μm to remove particulate pollution

7、Precise dosing liquid nitrogen speed could reach 300cpm, continuous dosing speed could reach 800cpm

8、Capacity adjustability and effectively vacuum liquid nitrogen insulation pipe ensure min liquid nitrogen consumption 

9、Advanced dosing valve ensures the transport of pure and liquid nitrogen.

10、Lowest outlet pressure of dosing valve ensures min liquid nitrogen splash.

11、No frost operating condition.

12、Precise adjustability of dosing amount and dosing time

13、Continuous self-monitoring through alarm indicator

14、PLC control/Touch screen/user-interface language selectivity

15、Could connect liquid nitrogen vacuum and heat insulation pipe, also could provide a complete liquid supply system from the liquid nitrogen storage tank to filling production line.

16、Small size and easy to install

17、Diversity machine types ensure to suit different capacity production lines.

18、Apply to all different sizes of pet bottles and thin-wall easy open cans production lines
