Coffee Valve with me. I like drinking coffee very much. I used to drink instant coffee until I went to my aunt's house once. She made me a cup of coffee with a coffee machine and made milk bubbles for me. I think it's very delicious. I have a deeper understanding of coffee and my love for coffee has deepened.

Coffee bag with coffee valve CS04

My aunt knew that I liked to drink, and she also sent me a box of eared coffee. Although I liked to drink coffee, at that time, I heard of eared coffee for the first time. I was very puzzled, what kind of coffee? Therefore, I also went to google search to find out what eared coffee looks like. My home doesn't have brewing tools, so I bought a coffee pot and a milk mug on the Internet.

Once, I won a bag of coffee beans in a lottery. I found the coffee beans are hard and I haven't tried to grind coffee yet. Because it is my first time to touch the coffee bean. I picked up the package and looked carefully. Then found holes in the package. I thought I had drawn a bag of leaking coffee beans. Later, I learned that this is a one-way degassing valve. The one-way degassing valve-CS04.

What is coffee valve CS04?

The one way valve CS04 without filter mainly for the bean productions, one way valve solved the problem and gives many roasters the opportunity to roast and package fresh coffee immediately. As a result, roasters extend distribution of fresh coffee and expand into markets previously outside their geographic scope.

In fact, the coffee valve can be used not only on coffee bags, but also on nuts, pickles and feed bags. Although it is small, it has great effect. Its function is releasing the CO2 outside the package. Keep your products fresh and aroma. Prevent the air getting into the package. The material of its body is resistant to high temperature and pressure.

This coffee valve is only 20mm, 5.5mm high, weight 0.95g, and its sealing range depending on sealing time and sealing pressure which can reach 160-220℃.The opening pressure is required to be 2.0-8.0mbar.

Although the outer diameter of One-Way Degassing Valve-CS04 is smaller than  2, its weight is heavier than One-Way Degassing Valve-CS02.It is sleek and more like a button. It is composed of silicon wafer, filter screen and high-density polyethylene shell.

My first time know coffee valve

First contact with the one way valve

Do you know when is my first time to know coffee valve? When I was cleaning up at home, I turned out a bag of coffee powder I had been reluctant to drink before. At this time, I opened it and found that it had become damp and caked, deteriorated and inedible.

At this time, my friend sent a new bag of coffee powder. I see that this bag of coffee powder is different from the previous one. It has some holes on it. I was confused.

I'm afraid that the coffee powder will become damp and caked. Why do I need to make a hole? Isn't this accelerating the speed of moisture?

My friend explained that the vent you said was called one-way degassing valve which also called coffee valve. Although it is small, it has great effect. It is mainly use for coffee powder, because it has a filter, it can prevent the powder from blocking the one-way degassing valve.

It can also use for the packaging bags of coffee beans, nuts, pickles and pet feed. Its function is releasing the CO2 outside the package. Keep your products fresh and aroma. Prevent the air getting into the package.

Sure enough, with this one-way degassing valve, my coffee powder is no longer so susceptible to moisture and caking, and the storage time is longer, and the quality is also very good. Thanks to a bag of wet and caked coffee powder, I know the product of one-way degassing valve.

Touch the coffee valve again

Now I am working at a factory which mainly producing the one-way degassing valve and valve applicator machine in China.

Our factory name Color Suns Company Limited. Color Suns One Way Valve & Valve Applicator Machine Factory, who mainly focus on producing "COLOR SUNS" One Way Valve and Valve Applicator Machine in China.

In this factory, the first product I know is the one-Way Degassing Valve-CS01.The coffee degassing valve CS01 with filter mainly for the ground coffee, coffee valve solved the problem and gives many roasters the opportunity to roast and pack fresh coffee immediately.

Fresh roasted coffee naturally gives off large amounts of CO2 (gas). The coffee valve naturally released CO2 creates an over pressure in packages and it must be released from a package by the coffee valve. Its function is releasing the CO2 outside the package. Keep your products fresh and aroma. Prevent the air getting into the package.

PP Coffee Valve

Secondly, PP degassing valve/ coffee valve. Some of package bags also produce by PP material, such as feed food or some food package bags or flexible package bags……

Due to the PP material only can hot melt with the PP material, so the PP package bags only can use the PP degassing valve.

BIO or Compostable Valve

Thirdly, BIO degassing valve or we call compostable aroma valve, this is new material to produce the one way valve, and it is 100% compostable, which will fit for the environmental protection requirement.
