The function of Color Suns One-way degassing valve(coffee valve)

Can you understand what is means for the first picture? 
If you don't understand,it doesn't matter,I will explain to you.
The function of the one-way degassing valve.
1.It will help you release the carbon dioxide outside the coffee bags.After your coffee beans have been roasted,it will produce many carbon dioxide,the carbon dioxide need to be released outside the coffee bags: 1.The carbon dioxide full of your coffee bags that will cause the coffee bags explosion.2.The carbon dioxide in your coffee bags will make your coffee beans or coffee powder oxidation.
Our one-way degassing valve open pressure is : ≥2.3-5.5 mbar.(It means that when you carbon dioxide arrival 2.3-5.5mbar that our valve will begin to release the carbon dioxide outside the coffee bags)
The closed pressure is :≤2 mbar.(It means that when you carbon dioxide get to ≤2 mbar,our one-way degassing valve will stop releasing the carbon dioxide and keep the coffee aroma into your coffee bags.That is why you can smell the coffee aroma when you see some coffee with valves in the supper market,and the customer will check are the coffee fresh through smell the coffee aroma.)
2.Maybe you will worry the Oxygen get into the coffee bags that also can make the coffee beans or coffee powder oxidation.That is why the valve called one-way degassing valve.Our one-way degassing valve can prevent the Oxygen getting into the coffee bags.All of Color Suns one-way degassing valve will do the vacuum test to ensure the quality.

One-Way Degassing Valve for the coffee bags.

CS01--One-way degassing valve

Powder or small particles products,mainly applied to coffee bags.Because of the one-way degassing valve 
combined with a layer of fliter paper,so you can effectively discharge coffee bags,carbon dioxide 
and prevent oxidation of oxygen into the bag making coffee powder without seeping makes packing bags of ground coffee.​

CS02--One-way degassing valve

Large granular products,mainly used in feed bags,

medical device packaging bags,pet food bags.

The one-way degassing valve applied to 

many aspects ,after roasting of coffee beans 

will produce large amounts of carbon dioxide,

at which point,the one-way degassing valve can 

exhaust our coffee bags in the carbon dioxide at the same time preventing the oxygen in the bag into the,guard against the bag the bag burst open without oxygen oxidation of coffee beans in the bag.

CSM01--One-way degassing valve applicator

This SemiAutomatic Valve Applicator made of 304 stainless steel tube,displayed by the digital modulator,control the temperature is stable and reliable,time relay control compression time,precision under pressure,with a foot switch to facilitate hand operation,fit for use by small air compressor required.Is free to transfer to another of different types of products needed to die,occupies a small area.Wide range of uses!This product is ideal for one-way degassing valve sticking pressure.

Aluminum Foil Bag--with one-way degassing valve

Aluminum has been the largest manufactured material in 2003 for coating and covering purposes in the suburbs of China and some other Asian countries due to its numerous advantages over the use of plastic for doing so!

Why we used the 304 stainless steel on our Semi-Automatic Valve Applicator?

Why we used the 304 stainless steel on our Semi-Automatic Valve Applicator?

Our One-way degassing valve need to be put into the coffee bags by the our Semi-Automatic Valve Applicator Machine.And our valve inserting machine are use the high quality table----304 stainless steel.

304 stainless steel is a universal stainless steel materials, anti-rust performance over 200 series stainless steel top. High temperature resistance are also good, generally use temperature limit of less than 650 ° c. Stainless 304 stainless steel with excellent resistance to corrosion and good resistance to intergranular corrosion. Oxidizing acids, derived in the experiment: in boiling nitric acid concentration ≤ 65%, 304 stainless steel with high corrosion resistance. Inorganic acids and alkaline solutions, and most organic acids also have good resistance to corrosion.

304 stainless steel is the most widely used form of chromium-nickel stainless steel, a widely used steel with good corrosion resistance, heat resistance, strength and mechanical properties at low temperature; good stamping, bending thermal processing, non-hardening heat treatment (non-magnetic, temperature of-196 ° c ~800 ° c). Atmospheric corrosion, industrial atmosphere, or if it is heavily contaminated areas, you will need to clean in a timely manner in order to avoid corrosion. Suitable for the processing, storage and transportation of food. Has a good workability and weldability. Plate heat exchanger, corrugated pipe, household goods (category 1, 2, tableware, kitchen cabinets, indoor pipes, water heaters, boilers, bathtubs), car accessories (windshield wiper blade, muffler, mold), medical appliances, building materials, chemistry, food industry, agriculture, ship parts, and so on.

Coffee and the Coffee Valve

Maybe you don't know the coffee valve.Maybe you will ask what is the coffee valve?What is the function of the coffee valve.
Don't worry.You can take a min to read my blog to know more about the coffee valve.
The coffee valve,also you can called it one-way degassing valve,air valve.
This coffee valve is used on the coffee bags.
The function of the coffee valve:
1.Release the CO2.
2.Protect the 02 into the coffee bags.
3.Keep your coffee fresh.

All the roaster know that the coffee bean and the coffee powder will release co2 after roasting.
When you roast coffee in small batches and then pack it the following morning, you use valved packs. It is because the coffee is so fresh it will keep on de-gassing. Packets would explode without a valve. Mass-produced coffee may not need a valve as it has been standing around the factory in between roasting, grinding and then (the enemy of coffee freshnesss) held in a hopper of a form-fill-and-seal machine. National and international low-grade brands of coffee for the mass market may not need a valve. Speciality coffee (i.e. coffee from one specific estate or farm) needs valve packs.
