Preservation

An exact dose of liquid nitrogen is introduced seconds before the seamer or capper. The volumetric expansion of the vaporized nitrogen pushes oxygen out of the container.

Key Benefits: oxygen reduction, extended shelf life, efficient nitrogen consumption, stabilization of organic products

Typical Applications: automobile oil, beer, condiments, wine

In Operation: documented studies show a 26% increase in shelf life and 90 to 95% reduction in headspace oxygen compared to traditional gaseous nitrogen purging

Pressurization in Packaging

A precise dose of LN2 is delivered immediately before capping or seaming. The trapped LN2 quickly vaporizes, pressurizing the container.

Key Benefits: lighter weight packaging, increased packaging rigidity, glass to plastic transition, eliminates package paneling, ease of labeling, oxygen reduction

Typical Applications: bottled water, energy shots, flax seed oil, juices (hot and ambient fill), teas, vinegar

In Operation: documented 9 gram reduction in PET bottle weight with Chart's MicroDose™ technology. Assuming the PET resin cost of $0.80/lb and a single production line running at 700 bottles/minute, this equates to an annual cost saving >$2.6 million.

Freezing

A dose of liquid nitrogen is introduced to "lock in" and surface freeze the product before it's transferred to a traditional tunnel or spiral freezer.

Key Benefits: maintains product integrity, aids in packaging and labeling, enables new products to be brought to market, enhances flavor and texture

Typical Applications: dipped ice cream cones and iCream Café

In Operation: liquid nitrogen flash freezing of ice cream cones provides stability and support through the packaging process resulting in improved overall aesthetics

Modified Atmosphere Packaging (MAP)

A large dose of liquid nitrogen is introduced into the package seconds before the seamer or capper.

Key Benefits: extended shelf life, oxygen reduction, reduced nitrogen consumption, stabilization of organic products

Typical Applications: baby formulas, coffee, nuts, trail mix, botanicals

In Operation: 46% reduction in nitrogen consumption using a Chart doser in lieu of traditional nitrogen gas purging

Full Equipment Solution

From initial design to a complete after-sales package, we work closely with our customers to ensure that the complete system is engineered and built in accordance with their requirements and always operating at peak efficiency. 

1. Storage: complete range of LN2 liquid cylinders, MicroBulk systems and bulk tanks.
2. Withdrawal: a vacuum insulated valve has the benefit of extremely low heat leak for minimum gas boil-off and eliminates unsafe ice build-up.
3. Vacuum Insulated Pipe: the foundation for heat loss efficiency and long-term integrity.
4. Phase Separator: provides extremely high-quality, low pressure LN2 on demand resulting in a continuous supply of unsaturated LN2.
