Features of high quality exhaust valve coffee bag:
1. The carbon dioxide released from roasted coffee beans is automatically discharged from the coffee bag.

3. Block the outside air from entering the coffee bag.
4. Prevent the coffee in the coffee bag from being oxidized and deteriorated.

Purpose of coffee bag exhaust valve: the one-way exhaust valve is installed on the coffee bag by the pneumatic pressure valve machine, and the hole is punched on the bag surface where the one-way exhaust valve is installed at the same time. The carbon dioxide released from the roasted coffee beans can be automatically discharged out of the coffee bag when it reaches a certain pressure.
In addition, the one-way exhaust valve with a filter screen can not only discharge the gas in the coffee bag and isolate the outside air from entering the bag, but also isolate the influence of powder on the exhaust valve and prevent the powder from spraying out of the bag to cause pollution.
It can not only effectively ensure the quality and flavor of coffee beans or coffee powder, but also prevent the coffee bag from swelling and bursting due to the accumulation of carbon dioxide, so as to prevent the coffee beans or coffee powder from oxidative deterioration.
