Our coffee valve's instructions
Our coffee bag valves comprise of a food-grade PE shell, sealing
rubber strips, sealing oil,which can enhance the performance.
You can make some concentrated pinholes on a coffee bean bag and
put a coffee bag valve on top of the holes.
It can exhaust the carbon dioxide produced by coffee beans while
preventing the outside air from entering the bag,so as to lower the
pressure inside the bag which would otherwise have the bag burst.
By doing so, you can keep coffee beans dry and original.
The Model V2 is fit for coffee bean packaging, it with good
degassing performance and reliable quality.
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.
