Waterproof One Way Degassing Valve Ground Coffee Packing Bag Degassing Valve
Introduction:
The one way degassing valves is especially suitable for bean coffee and ground coffee.
The coffee one way degassing valve effectively vents CO2 gas build-up while sealing-out environmental oxygen, moisture and contaminants.
Our one-way degassing coffee valve allows coffee to be packed immediately after roasting without the concern of coffee degradation.
Freshly roasted coffee releases gas and continue to do so for up to 7 days. Our coffee one way degassing valve will help release the gas while preventing air.
Installing our one way degassing coffee valves is a must for coffee packaging.
This allows roasters to pack freshly roasted coffee immediately without the worry of having the bag burst open due to trapped air.
Every one way degassing valve is tested to ensure highest performance.
Quality control tests ensure consistent opening and closing pressure and periodic tests with fresh product are done on a routine basis to verify real life performance.

FQA:
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.
