The liquid nitrogen dispenser is designed to create a pressure and inert environment in packaging containing "calm" liquids (such as oil, water, juice, wine, beer, low alcohol beverages, etc.) and food (ketchup, nuts, potato chips, breadcrumbs, etc.). This machine is suitable for any packaging container, including aluminum cans, glass, PET , and other types of plastic.
The ability to automatically create over-pressure and inert environments is a revolution in the packaging industry to some extent. After a drop of liquid nitrogen is injected into a bottle or container, the evaporation is strong (boiling point - 196 ° C)
When it becomes a gas, its volume increases by 700 times. This physical phenomenon can do two basic things:
First, before packaging, the remaining air and oxygen are squeezed out of the bottle and replaced with inert gas nitrogen, thereby extending the shelf life of the product;
Secondly, after sealing, the evaporated liquid nitrogen will generate additional pressure, greatly improving the rigidity and strength of aluminum, RET, and other plastic containers. This is necessary for reasonable storage and transportation, and to prevent the "vacuum rupture" effect of hot products when cooled in closed containers.
Using a liquid nitrogen dispenser, it is possible to successfully package cold liquids, hot ketchup, cooking oil, dessert syrup, wine or coffee concentrate into PET containers.

Aseptic Liquid Nitrogen Dosing Machine 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 package, Meanwhile, prolong  canned food or beverage shelf life, keep good looking for better transportation and store.
