In order to extend the shelf life of coffee and prevent oxidation, one way degassing valve invented by Foshan Shunde Huazhong Industry Co., Ltd. plays a key role. The HZV6 Valve and HZV6F Valve are cleverly designed to allow gases such as carbon dioxide to be released naturally while blocking the entry of external oxygen. As carbon dioxide is released, the pressure in the package will gradually increase, causing the flexible rubber gasket to deform and release the gas. The one way degassing valve can detect the aroma of coffee to determine the freshness of coffee. Fresh coffee has a strong aroma. If you want to check the freshness of coffee beans before buying, just gently squeeze the bag and the gas will be released through the valve. Smell it. If the aroma is strong, it means that the coffee beans are fresh; if the aroma is weak, the coffee beans may not be fresh enough.
