The coffee 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
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.
Frequently Ask Questions of One Way Degassing Valves:
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
