Environment Friendly Good Degassing Packaging Bag Coffee Valve for Coffee Beans Roasted Packaging Bags

Product Description : 

Here's how the coffee valve works and its key features:

Design: Coffee valves typically consist of a plastic or metal housing with a silicone or rubber membrane covering small perforations. This design allows gas to escape from the coffee packaging while preventing air from entering.

​

Functionality: The one-way degassing valve operates based on the principle of differential pressure. As freshly roasted coffee beans emit carbon dioxide gas, the pressure inside the coffee packaging increases. The valve allows excess gas to escape, maintaining the internal pressure at an optimal level.

​

Installation: Coffee valves are usually installed on coffee packaging, such as bags or pouches, during the packaging process. They are typically placed on the front or back of the packaging near the top to ensure proper gas release.

​

Material Selection: The materials used in coffee valve construction are carefully chosen to ensure durability, flexibility, and resistance to coffee oils and aromas. Silicone or rubber membranes are selected for their elasticity and gas-permeable properties.

​

Quality Control: Manufacturers conduct rigorous quality control checks to ensure that coffee valves meet industry standards and specifications. This includes testing for gas permeability, pressure resistance, and seal integrity.

​

Compatibility: Coffee valves are designed to be compatible with various types of coffee packaging, including bags, pouches, and containers. They come in different sizes and shapes to accommodate different packaging requirements.

​

Benefits: The use of coffee valves offers several benefits, including extended shelf life, preservation of coffee flavor and aroma, prevention of bag bloating or bursting, and improved product quality.

​

Applications: Coffee valves are commonly used in the coffee industry for packaging freshly roasted coffee beans and ground coffee. They are also utilized in other industries where pressure relief and gas release are essential, such as in packaging for roasted nuts, grains, and specialty foods.

FAQ  : 

1. What is coffee One Way Degassing valve?
One way degassing coffee valves are vital to maximizing freshness by allowing freshly roasted coffee to degas in the package. Our one way degassing valves are industry proven to effectively and effectively vent CO2 gas build-up while sealing out environmental oxygen, moisture and contaminants.

2. Can the coffee valve customized to allow air to escape more quickly for larger package?
We can also custom fabricate valves to meet specific requirements.

3. Can one way degassing coffee valves be used under water?
We do not recommend that coffee one way degassing valves be used while immersed in water.

4. What is the purpose of silicon oil? How does the performance change without the silicon?
It is so that air will not come back in after a while. Most products packaged with valves are sensitive to oxygen and moisture, and the silicon oil ensures that it functions as a one way degassing valve.
