It is important to know the process of coffee roasting because it is the most important reason of using value and zipper. The coffee beans will be expended when they are roasted and the SILVERSKIN which is easy to cause fire started dropping. Also water within beans evaporated. Carbon dioxide and steam will be produced. The vacuum packing will burst for these gases. When starting to release them, the coffee beans will be oxidated by oxygen and they will be deteriorated. That’s it need a packaging with  special air value. It is a kind of unidirectional value which means the carbon dioxide can be out by this value and oxygen can’t touch the beans.

To make a long story short, the value has three functions. First and foremost, it is damp proof so it is easy to preserve. Second, it is could protect beans when collision happened. The gas within packing will be released from the value and reduce the possibility of risks. Third, customers can smell the taste of beans which will help them to buy the satisfied beans.

However, it has some shortcoming. For example , the smell of coffee beans can only last for a month and then it will be disappeared by the time. But sealing the value can maintain for a long time . At the same time , just Roasted Coffee need to use these value.
