What is the valve applicator machine?
We can find that, all the coffee bag will with 1 -6 holes on it. And the customers can smell the coffee from those holes.
Do you know what is that hole mainly used for? How to make this hole on the coffee bag?
Firstly, let me tell you what is that hole mainly used for: It is a small coffee valve beside that hole. It mainly used for keeping the roasted coffee bean or coffee powder fresh and aroma.
Maybe you don’t know, after the coffee bean been roasted by the coffee roaster, they will produce many C02 from the coffee bean.
When they need to be packed into the coffee bag, the roasted coffee will cause the coffee bag full of CO2.
If we don’t use that coffee valve to release the CS02 out of the bag, it will cause the coffee oxidation .
When the customers received a bag of coffee, it will effect the aroma or taste of a cup of coffee.
Secondly, do you interested in how is the small coffee valve be installed into the coffee bag?
It is very easy, only need 1 unit of valve applicator machine.
