Nitro cold brew coffee is now very popular in recent years, it also called "NCB".It will be a richer, less sour taste， less acidic than hot coffee because the beans are steeped for hours (or even days).
How to make the nitro coffee?
As we know, Nitrogen gas does not easily dissolve in water, but it can give the brew a thicker, more velvety mouthfeel.
Usually we use the equipment to infused with nitrogen gas is released through a pressurized valve with tiny holes, then high pressure forces the cold brew past a disc make creates a creamy, stout-like effect.
But as for the nitrogen coffee canning factory, they usually use the liquid nitrogen doser inject the liquid nitrogen in the cold brew before can sealing. please see the advantage for the liquid nitrogen injector:
1.Lightweight PET- reduce the weight of PET for cost and environmental savings
2.Glass to PET Transition - eliminate glass safety hazards and weight of containers
3.Bottle Rigidity - maintain bottle shape even with lighter weight containers
4.Eliminate Paneling- increase the internal pressure to offset paneling issues
5.Oxygen Reduction- create an inert environment to preserve product freshness
6.Extend Shelf Life - minimize oxygen levels
7.Ease of Labeling - consistent bottle rigidity creates an efficient labeling process
8.Reduce Nitrogen Consumption - measurable and repeatable liquid doses
9.Maximize Warehouse Storage Space- increasing product
Stabilize utilizes less square footage
10.Stabilize Organic Products - extend shelf life without preservatives
