How to classifiate filling machines by air pressure

Filling machines are an indispensable packaging machine for us living in this society. The possibility of seeing filling machines in the environment around us is very small. For most of us, they are behind the scenes. Silently dedicated selfless person, but it has changed our lifestyle to a great extent. When we travel, when we are at home, we don’t need to fill the container from our house when we go to the street for dinner, just buy it from the store, and many of the supplies in our lives are filled Machine packaged. The huge market and unlimited usage make us yearn for it.

Then we need to have a simple understanding of it before buying. The following is a brief introduction to the classification of the filling machine's pneumatic filling method as a standard.

Pressure canned

Pressure filling is like the injection device we have seen that the pressure inside the material container is higher than the pressure of the external environment to quickly inject the material into the packaging container. It is often used in the rapid production of liquid packaging production lines.

Atmospheric filling

It uses gravity to make the material flow into the packaging container by its own weight. This type of filling method is suitable for products with low viscosity.

Vacuum filling

It is similar to pressure filling, which also uses the difference in pressure to fill the product into the packaging container. It uses the evacuation of the gas in the packaging container to make its pressure lower than the pressure of the material container. This type of filling method has a wider scope of application than the first two.
