When we are shopping for coffee, do we find that a round exhaust valve is often seen on the surface of the coffee bag, and there is a circle of small holes around it. Talk about the role of this coffee exhaust valve.

This coffee valve is a one-way exhaust, so it is also called a coffee one-way exhaust valve, which is used to exhaust the gas in the coffee bag in one direction.

Because after the coffee beans are roasted, the ingredients in the green coffee beans will produce a series of chemical and physical reactions, and gas will be generated during the reaction. If there is no one-way exhaust valve installed on the coffee bag, the coffee bag will be filled with gas, which will easily expand and burst. At this time, if there is a one-way exhaust valve, the gas in the bag can be exhausted and at the same time it can be prevented. The air outside the bag enters to achieve the purpose of preservation.

In addition, if there is this one-way exhaust valve, it will be more convenient for us to buy coffee. As long as you squeeze the packaging bag, you can smell the coffee in the bag and choose the coffee you like more.When we are shopping for coffee, do we find that a round exhaust valve is often seen on the surface of the coffee bag, and there is a circle of small holes around it.

There are two types of coffee exhaust valves:

One is without filter, suitable for coffee beans;

The other is with a filter, suitable for coffee powder. The exhaust valve with filter screen filters the powder in the packaging bag, which can effectively prevent the powder from spraying out of the bag and causing pollution.
