Packaging Exhaust Solution Expert

We are a professional manufacturer of one-way exhaust valves, which are strictly controlled by design, manufacturing, testing and quality.

In order to manufacture a good quality valve that truly has a one-way exhaust function, we have invested considerable effort and time to continuously study exhaust and seal testing. The function of the one-way exhaust valve is to discharge the carbon dioxide gas in the bag, maintain the appropriate pressure in the bag, and prevent the external oxygen from entering, so that the oxidation rate of the product in the bag is too fast and the retention time of freshness is too short.

We are more active in launching the "filter-type one-way exhaust valve" This filter can filter fine powder, suitable for coffee powder, but also suitable for very fine powder.

In addition, we also aims at fermented feed manufacturers with certain requirements for the exhaust effect of the air valve, and specially launched a special air valve solution tailored to meet the user's requirements for large and fast exhaust.

If you have troubles in packaging exhaust, welcome to contact us. We are the Packaging exhaust solution expert, and will be your packaging exhaust partner.

What is the coffee bag one way valves?

The coffee one way degassing valves is especially suitable for bean coffee and ground coffee, even for feed.

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.

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 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 product are done on a routine basis to verify real life performance.

How to tell if Coffee is bad, rotten or spoiled?

Practicing proper hygiene and food safety techniques will help prevent food born illness.

Since coffee basically looks the same with age, many ask does coffee go bad? The best way to tell if it has gone bad is to use your nose. If coffee has gone bad, the pleasant aroma will be gone and with it much of the taste. Using this coffee will not harm you, but will just not have much flavor if the smell is gone. It may also lose it's deep dark color and appear a lighter brown.

Coffee beans begin to slowly lose their flavor soon after grinding as the oils begin to evaporate. How long you choose to use your coffee after the best by date really depends on how particular you are about the taste of your coffee. Some prefer not to use it and some may use it even after the eat by date (not recommended) but use an increased amount to regain the stronger coffee taste.

Of course, certain health risks associated with spoiled drinks, so remember to practice food safety and enjoy your drinks before their shelf life has expired!

How to use extra before your Coffee goes bad?

If you made too much this morning and don't want to toss it down the drain try one of these ideas. Pour the cooled coffee into a blender along with a scoop of vanilla ice cream, milk, a handful of ice and a teaspoon of vanilla. Whip that up for a yummy treat of coffee milkshake that will surely get you through the rest of the day!

 Pour it into old ice cube trays (those old plastic ones that you don't know what to do with). You can freeze them and then throw the cubes into gravy as a browning agent.

 Use prepared coffee in place of water in your vanilla or chocolate cake recipe to give it a mocha flavor.
