Product Details

WQYDJZ-1 Liquid Nitrogen Dosing Machine is the latest liquid nitrogen dosing machine in China after takes the similar machines abroad for reference. 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.

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.

Working Process:

1、Supple of Liquid Nitrogen: Regulate to 15 (0.1MPa) and connect to liquid nitrogen pipe.

2、Compressed Air or Nitrogen: Supply to the working of dosing valve. The pipe diameter must be 1/4inch diameter and pressure range is from 50psig to 100psig (3.4 to 6.9 bar). Set the pressure to 50 psig (0.35MPa). Please do not set the pressure too high, high pressure means high impact, it will shorten the lifetime of dosing valve element and internal vacuum pipe.
