one way degassing valve knows that people who love coffee, they always keep several kinds of coffee bean at home. Such as bright and slightly acidic Yirgacheffe, the fragrant Mandeling, the scented Geisha, etc... But the preserve time of coffee beans is longer, they will face metamorphic problems, then how to preserve coffee beans has become a big problem for coffee lovers, today we will answer you how to solve this problem.

1. Use upright sealed can or sealed bags

The proportion of carbon dioxide is higher than the air, so in the same confined space, carbon dioxide will precipitate at the bottom, and air will float in the upper layer. The carbon dioxide released by fresh coffee beans will stay at the bottom of the container and form an antioxidant layer. In order to protect the coffee beans, it is best to use the storage packaging to stand upright to preserve the coffee beans.

2. Use long coffee spoon to take out coffee beans

Carbon dioxide has a higher specific gravity than air and therefore it will precipitate on the bottom of the container. When taking out coffee beans, avoid using the method of pouring the coffee, otherwise the carbon dioxide in the container will be outwell, and more air will enter into tank to accelerate the metamorphic of the coffee beans. The correct approach should be to use a long spoon to reach the bottom of the container to take out the beans.

3. Use a vacuum tank or vacuum bag.

The vacuum storage tank will form a vacuum state. The vacuum state means that there is no oxygen and water vapor. It is a good place for preserving coffee beans. It is also necessary to pay attention that the coffee beans should not be exposed to sunlight directly. Because the light is the catalyst of oxidation, when at the state of no light, it can be slow down the rate of oxidation.
