Exhaust coffee raw beans contain acidic substances, proteins, esters, carbohydrates, water and caffeine. After the coffee raw beans are roasted at high temperature, a series of chemical reactions such as Merida reaction will produce carbon dioxide. Generally speaking, carbon dioxide released after roasted coffee beans and 2%of other volatile gas accounts for 2%of the coffee beans. 2%of the gas will slowly release from the fiber structure of the beans, and the release time will be related to the baking method. Because of the volatile carbon dioxide by the coffee beans, we will see that the roasted coffee beans are packed in a sealed bag and it will bulge over time. This is what it is called "rising bag". With one -way exhaust valve, it will help these inert gas to eliminate the bags in time, and will not allow these gases to oxidize coffee beans and maintain a good fresh state for coffee beans. 2. How to get the air isolate the air while the air is exhausted? One -way valve is different from ordinary air valves. If ordinary air valves are used, while the gas inside the packaging bag is discharged, the air outside the packaging belt is also allowed to flow into the bag, destroying the sealing of the packaging bag, so that the coffee will continue to oxidize. Coffee beans oxidize the aroma and volatilize, and the ingredients are deteriorated. The unidirectional exhaust valve does not do this. It discharged the carbon dioxide in the bag in time without allowing the outside air to enter the bag. So how does it not allow the outside air to enter the belt? The fertile air valve tells you the working principle: When the gas pressure in the bag reaches a certain threshold, the valve of the unidirectional exhaust valve is opened to release the gas in the bag; until the air pressure drops below the threshold of the unidirectional valve. The valve of the one -way valve is closed, and the packaging bag is repaid to the sealing state.
