Product Description

WYD-300 Liquid Nitrogen  injection Machine for Pet bottle or aluminum can is the latest dosing machine in China .

It  has the advantage of

Accurate dosing volume,

No-container-no-liquid dosing

Small size

Easy installation and maintainance

Suitable for any filling production line

Siemens PLC control system with touch screen,

Vacuum heat-insulated pipes ensuring minimum consumption of liquid nitrogen

No frosting operation condition

Liquid Nitrogen Injection 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 pacakge, Meanwhile, prolong  canned food or beverage shelf life, keep good looking for better transportation and store.

Key Advantage when using liquid nitrogen injection machine 

• Strengthen lightweight PET package  –  reduce the weight of PET for saving cost and environmental friendlyrequirement.

• Container rigidity – maintain shape even with lighter weight containers

• Oxygen reduction – Create an inert environment in container to keep product fresh

• Extend shelf life – minimize oxygen content

• Ease of labeling – consistent container rigidity creates an efficient labeling process

• Maximize warehouse storage space – increasing product stackability utilizes less square footage

• Stabilize organic products – extend shelf life without preservatives

Liquid Nitrogen Injection Machine 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.
