CryoGenic - LN2
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, canned peanuts, container stabilisation
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
Container (bottle or can) stabilisation/ pressurisation
A precise dose of LN2 is delivered immediately before capping or seaming. The trapped LN2 quickly vaporises, pressurising the container.
Key Benefits: use of light-weight packaging, increased packaging rigidity, glass to plastic transition, removal of O2 and elimination of container/package panelling, support for labelling application, oxygen reduction
Typical Applications: non carbonated products in bottle or Can (ie. water, wine,...), energy shots, flax seed oil, juices (hot and cold fill), teas, vinegar
In Operation: documented 9 gram reduction in PET bottle weight with LN2-technology. Assuming the PET resin cost of $0.80/lb and a single production line running at 350 bottles/minute, this equates to an annual cost saving >$1.3 million.
