HOW IT WORK ?
One way degassing valve is a small plastic product looks like a fastener,it is designed for packaging bag that used to store the goods that would produce gas.One way degassing valve allows the CO2 escape from the bag while prevent the air enter the bag,so the goods can be avoided to be oxidized,and itcan be kept in high quality.

ADVANTAGES
The One way degassing valve,coffee valve,coffee degassing valve, or degassing valves are a form of MODIFIED ATMOSPHERE PACKAGING (MAP) used in a multitude of industries but are especially popular in the coffee market. The coffee can be packed immediately after the roasting process to keep the aroma and flavor. Here's why: As carbon dioxide gas builds inside of the package, (the One way degassing valve,coffee valve,coffee degassing valve, or degassing valves) allows it to escape while at the same time preventing oxygen and other contaminants from entering. our products are truly implements functionality of one way degassing.
1.Prevent bag expansion
After roasting,coffee releases carbon dioxide gas at rates of up to 1000cc per pound for a period of days to weeks.
2.Smell fragance
Over 800 aroma components are responsible for a distinctive coffee quality.
3.Resistance to bursting
The valves allow the roasting gasses to escape and avoid bursting of the bag without valves.
4.Prevent freshness
Freshly roasted coffee is very sensitive to oxygen.Without product protection it would only conserve its flavor for 4 to 6 weeks.
5.Prevent oxidation
Keep oxygen and moisture out of the bag and prevent oxidation of coffee beans.
6.Imported materials
Using PE raw materials from the united states, it is environmental protection and pollution-free.

SCOPE OF APPLICATION
It is suitable for compound packing bag which needs to vent gas.

HOW TO INSTALL THE VALVE ON THE BAGS ?
 At WOJIN, coffee degassing valve is our main core products, so we've invested in creating degassing valve applicator to meet customer's need.
 
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 1~6) holes in the bag which the valve covers.

                                         How to Distinguish the Quality of One Way Degassing Valve
One way degassing valve has a big effect on the goods that would create gas, but only high quality one way degassing valve has obvious effect, if the one way degassing valve is not good,it can't has such an obvious effect. So, how to distinguish the quality of the one way degassing valve is important to the customers.
There are several ways to distinguish the quality of one way degassing valve.

1.distinguish according to the structure.
This is the simplest way to distinguish its quality.
1)Check if the one way degassing valve has a adhesive, which is used to seal the rubber disk to the polythene base. If there is lack of the adhesive, the rubber disk can't connect to the disk tightly, the entrance of one way degassing valve is easy to open so that the outer air woud enter the packaging bag to oxidize the goods.
2)watch the gloss of the one way degassing vave, good one way degassing valve must use good material. If its appearance looks glossy and seems transparent, the one way degassing valve is good. On the contrary, if the one way degassing valve does not looks glossy and transparent the one way degassing valve is inferior.
3)be sure if the one way degassing valve is lack of any part and material, a good valve can't lack any part of the five basic components, the polythene base, the bottom cap, the rubber disk, the adhesive and the filter.

2.test the freshness of coffee
If the one way degassing valve is used to coffee packaging, make a cup of coffee and test the freshness of coffee is a good way to distinguish the quality of one way degassing valve .It's better to make a comparison in different time, for example, do the experiment after one month, two months, three months and longer time using the valve writ down the test result and make comparison. Compare the foam volume when making coffee and the acidity of the coffee. If there still are 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 aim to help venting the air that produced by the feed. If the one way degassing valve is good, it can help keeping the high quality of fermented feed for a longer time. If there are gas trapped in the packaging bag, or the fermented feed is moldy, It's no doubt that the one way degassing valve is inferior.
Many users concerned about the quality of one way degassing valve, but they don't know how to distinguish, here I introduced three ways to them. If you have any other ways to distinguish the quality of the one way degassing valve please share with us, Let's spread more information and knowledge to the people who is desire to know.
