4. Prevent the coffee in the coffee bag from being oxidized and deteriorated.

5. The quality and flavor of the coffee beans are guaranteed to remain unchanged.



The purpose of the coffee bag exhaust valve: the one-way exhaust valve is hot-pressed to the coffee bag by a pneumatic pressure valve, and at the same time the hole is placed on the surface of the bag where the one-way exhaust valve is installed, and the roasted coffee can be baked. The carbon dioxide released by the beans is automatically discharged outside the coffee bag when a certain pressure is reached.

In addition, the one-way exhaust valve with filter screen can filter the powder in the bag, and in addition to the function of discharging the gas in the coffee bag and insulating the outside air into the bag, it can also isolate the influence of the powder on the exhaust valve and prevent the powder.
