Hanging ear coffee packaging machine to keep coffee fresh?
The answer is nitrogen preservation.
“Nitrogen” is an inert gas, tasteless, odorless, almost insoluble in water, is not easy to chemical reactions, and has no effect on microorganisms. Filling nitrogen into the earbag can effectively block the contact between oxygen in the air and coffee powder, that is, make coffee enter a relatively “dormant state”, so as to achieve the effect of anti-oxidation, retain the aroma of coffee completely, and keep the flavor for a long time.
However, if you look closely, you will find that most of the hanging ear coffees on the market are handmade products of small coffee shops. They do not use nitrogen gas, but are kept fresh by simple desiccant. Even though some use small packaging devices and tanks of nitrogen, this is not as effective as continuous packaging in factories.
However, the manufacturer of KST coffee packaging machine uses high-end ear bag machines to fill the whole production with nitrogen and isolate oxygen, which is more natural, more sanitary and has no side effects than desiccant. Each pack of hanging ear coffee is 98% nitrogen content, 3600 bags per hour packaging speed, in the way of continuous packaging. Therefore, if you want to pursue the ultimate coffee experience in your coffee factory, you should choose a reliable packaging machine manufacturer like KST.
