Liquid Nitrogen Dosing System Working Process

      When liquid nitrogen vaporized, the volume expansion 700 times, extrude the air out and vacuum the can,increase the aluminum can/pet can internal pressure to strengthen the pacakge, Meanwhile, prolong  canned food or beverage shelf life, keep good looking for better transportation and store.

Operation Conditions

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 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.
