14.How to know whether a bag of coffee fresh or not? By the coffee valve.

Maybe the coffee bean after roasting by you,it is fresh and aroma.We can ensure that all the coffee are fresh after they have been roasted by all the roaster.

But how to keep the coffee fresh when they are on the shelf at the supper market? Or when they are one the coffee shop? Or when they are on the way to your clients' hands? 

How to keep the coffee bean fresh,it seems not a very difficult question,maybe you will think that a good coffee bag that is ok. And maybe you also will think that a good coffee bag with zipper that is ok.

I agree with your thought,a high quality of coffee bag is one of the most important role for keeping the coffee fresh.But not enough.

As you can see,some bag of coffee ,have done the vacuum package.Yes,that also a good way to keep the coffee fresh,it have vacuum all the air outside the coffee bag.That also one of the good way to keep the coffee fresh.But how about the coffee aroma? 

Why don't you try to install a coffee valve into your coffee bag?

First,the coffee valve not only can release the co2 outside the coffee bag,but also can keep the coffee aroma into your coffee bag.Why you can smell the coffee aroma through the holes on the bag? That is because of the coffee valve have the close pressure,while the inside co2 not enough their lowest value,they will stop releasing the co2 outside the coffee bag,and keep the coffee aroma in the bag.

So you can know whether a bag of coffee fresh,smell the coffee aroma through the coffee valve,I think that is the vacuum package can not do it.

Why the Coffee Package need the Coffee Valve?

Maybe you are very confused for the coffee valve in your coffee package.Maybe you don't understand what is the coffee valve.

Now pls spend sometime to read this post.Welcome to share us your opinion about this post.

The green coffee will be roast by the roaster,and the coffee bean will release more and more co2 after roasting.Then pack the coffee into the coffee bags.

If your coffee bag without the coffee valve,the co2 will full of your bag,then your coffee bag will be exploded by the co2.

That is why you will find the coffee package with the coffee valve in it.The coffee valve can help you release the co2 outside the package. 

Maybe you also know the open pressure and the close pressure of the coffee valve.Pls check the below coffee valve:

The open pressure of the valve is :2.3-5.5 mbar.It means while the co2 in your coffee package arrival 2.3-5.5mbar,the coffee valve will begin to release the inside co2 outside the bag.

The close pressure of the valve is :less than 2mbar.It means while the co2 in your coffee package less than 2mbar,the coffee valve will stop releasing the co2 outside the bag,and keep the rest of coffee aroma in your coffee bag.That is why your client can smell the coffee aroma through the coffee valve on the package,to confirm this bag of coffee is fresh or not.

Welcome to share or discuss your opinion about the coffee valve with us.

Thank you for your time.
