How is Nitrogen Used in Packaging Bakery and Snacks?
You may also note that when you open a new bag of bread or cake, half of the bag is stuffed with "air". That air is without a doubt nitrogen gas. Nitrogen is an inert gas, and is used at some point of the packaging system to rule out and eliminate air and in particular, oxygen. Oxygen is highly reactive, so this ability it likes to mix with different molecules, which affects in meals spoiling or dropping its' freshness. By the use of nitrogen to push out the oxygen in bread or cake bags, the shelf lifestyles is extended, and the integrity and first-class of the chips and snacks are kept.
Because meals and beverage producers are continuously the usages of nitrogen, having an on-site nitrogen generator can retailer a lot of cash and time, in contrast to outsourcing a furnish of nitrogen. Pneumatech presents fuel turbines that provide up to 99.999% high-purity nitrogen gasoline for more than one meals and beverage application. So how is nitrogen gas added to bags of bakery products?
Most bakery manufacturers use a generic HFFS machine that is using Modified Atmosphere Packaging (MAP) to add nitrogen to the bakery bags. The speed of the bakery packaging machine will be slow to guarantee the bag injects enough nitrogen inside. Normally the packaging speed is 100-120bags per minute.
