69.Why the one way coffee valve with filter will release the CO2 slower than one way coffee valve without filter ?
As usual, there are two kinds of one way degassing coffee valve you will see in the market.
1.One way degassing valve without filter, this kinds of coffee valve mainly used for roasted coffee bean or whole coffee or bean products.
2.One way degassing valve with filter, also called filter valve. This kinds of filter valve mainly used for roasted ground coffee, coffee powder or powder products. It is update from coffee valve without filter.
Because your powder products, or ground coffee, There are a lot of powdery objects in your flexible package, you must have the filter to prevent it . So at this moment , you must use the one way degassing valve with filter(filter valve). The coffee valve with filter can prevent the ground coffee getting into your valve, and effect the function of your degassing valve.
If you are using the coffee valve without filter now, Your ground coffee will get into your coffee valve, and stuck into the coffee valve, you also will see the ground coffee have come out the coffee package from this coffee valve.
And while we are using the coffee valve with filter , we will found that the valve with filter will release the CO2 slower than the valve without filler.
The reason:
1.Firstly, the CO2 from the roasted ground coffee is less than the CO2 from roasted coffee bean. So the filter valve release the CO2 is slower than the valve without filter.
2.Secondly, the filter can reduce the speed of release CO2 from the coffee valve with filter.
So, while you are choosing the one way degassing valve or coffee valve, please decide which kinds of coffee valve or degassing valve you will use for your ground coffee or coffee bean.
