The one way degassing valve is importance in our life ,which mainly used in food ,tea, fermented feed and other packaging bags, but there are still many people who do not understand the installation method of one way degassing valve.
To install the one way degassing valve on the packing bag, which need the special pressure valve machine .Nowdays, there are all kind of valve applicator on the market, but the quality is uneven. Even if the price is high, it may not be of good quality. Low price valve machine, there is no quality.
To install the one way degassing valve ,it is best to choose a professional production of one way degassing valve and semi automatic valve applicator of Wojin plastic factory.If the one way degassing valve and semi automatic valve applicator buy from different factory , then may cause the semi automatic valve applicator can not press the valve. The reason is: different brands of coffee valves and valva applicator corresponding to the size of the pressure valve deviation.
Then how to choose the appropriate semi automatic valve applicator for hot pressing one way degassing valve?
To hot pressing the one way degassing valve ,you can choose Wojin semi automatic valve applicator VM01 and VM02 ,these two model need us put the valve and bag by hand ,use the foot pedal to finish press process of coffee bag . If the one way degassing valve is to be heated on a larger packing bag, such as a feed bag, the valve applicator can be pressed 400-600 times per hour. If the one way degassing valve is to be heated on a smaller packing bag,the valve applicator can be pressed 600-800 times per hour. In addition, if you need to install the valve of the bag is relatively thick, you can choose semi automatic valve applicator VM04, because the pressure bag is thicker and the bag is more beautiful.. In general, if the order is given enough time, the speed of the two semi automatic valve applicator can meet the general production requirements of the customers.
But if the above VM01 and VM02 are too slow, then the model VM04 semi automatic valve applicator is your first choice. This semi automatic has two model, one is in manual mode ,vibration plate will sent the valve to the base ,then we need to take the bag and step on the foot switch; the other is in automatic mode, switch on the automatic mode, vibration plate will be send the valve to the base ,the infrared sensor is automatically induced,and the machine will automatically install the valve.
The semi automatic valve applicator VM04 is the fastest of the three semi automatic valve applicator. It can heat 720-1000 one-way degassing valves on the packaging bags per hour. If the pursuit of high-efficiency manufacturers, choose semi automatic valve applicator VM04, you can definitely save a lot of resources.
In addition, if it is considered that the pressure valve is troublesome and it is more convenient to operate, the sticky type label valve is the best choice. This type of label valve does not need to be hot-pressed by a valve press, but is a one-piece type, requiring manual paste. The advantage is that it does not occupy a position, and it is light and beautiful.
The above is the installation of one-way exhaust valve method, do you understand?

Remember to seal the packaging bag after taking some coffee out, so the one-way degassing valve would finish its job to keep the freshness of product.03 Jul 2020
Roasted coffee cannot be put directly into a sealed package, because the coffee need to "breathe", that is, the carbon dioxide gas will be released.26 Jun 2020
This is a hole punched before installing the degassing valve, which purpose is to discharge the CO2 released and avoid the oxidation of coffee.
