What is the role of the one-way exhaust valve of the coffee bag? To keep coffee beans properly for one month, it must require a low oxygen, dry, low temperature, low light environment.
At present, cafes are generally packaged with aluminum foil composite materials, plus a one-way exhaust valve. Because the coffee beans have just been roasted, they will start to emit a lot of carbon dioxide. One of the functions of this exhaust valve is to release the emitted carbon dioxide to prevent the bean bag from bursting, and at the same time prevent the oxygen outside from entering the bag, which will oxidize the coffee beans and cause the loss of flavor.
If the beanbag itself has a zipper after opening, please be sure to exhaust as much air as possible before closing the zipper. If there is no zipper, it is necessary to fold the belt several times and then clip it with clips to avoid air circulation as much as possible.
