Product Description :

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 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.

HOW TO INSTALL THE VALVE ON THE BAGS

The one-way degassing valve is our core product. The installation of degassing valve will need the pressure valve machine to hot pressing it on the bag.

1. The valve applicator holds the die head in the correct position underneath the seat for valves.

2. It pressed down the die head by heat sealing the valve to the bag.

3. The pin pokes a tiny (can be 2~6) holes in the bag which the valve covers.

Application:

How to Distinguish the Quality of One Way Degassing Valve?

1.The easy way to test it is by pumping the air from the bags with one way degassing valve after sealing, and then see if the bag will expand or not.
2.Test the freshness of coffee
Making a cup at different times, one month, two months, or even three months longer time using the valve, write down the test result and make the comparison, Compare the foam volume and the acidity of the coffee, if there still is a lot of foam and the coffee taste less sour, it is said that the coffee is kept well. Otherwise,,the one way degassing valve is not good and can't keep the freshness of coffee effectively.
3. Check the fermented feed
The one way degassing valve placed in the packaging bag aims to help vent the air that is produced by the feed to keep the high quality of fermented feed for a longer time. If there is gas trapped in the packaging bag, or the fermented feed is moldy, it's no doubt that the one way degassing valve is inferior.
