The pumping character of the vacuum machine
The primary purpose of the vacuum machine is to vacuum seal the containers of meals. In other words, whether they are plastic bags, boxes, or bowls, in any case, everything that can hold food, this machine must be able to remove all the air it contains. It thus plays a role as a pump, but here it sucks the air inside, unlike the classic pumps we know. With it, vacuum packing becomes much easier.
The vacuum sealing machine is more often used on bags that serve as meal containers. When the machine removes the air from the bag, it then seals it, which is the vacuum sealing process. You will notice that the bag completely adheres to the food it contains. If it is, for example, meat, the bag once vacuum sealed becomes like a second skin for the meat.

How to use the vacuum machine?
To use the vacuum machine, you must first position the bag so that its opening is at the vacuum mouth. This is essential; otherwise, the operation would have served absolutely no purpose. Once the opening of the bag is in the vacuum mouth, you close the lid of the machine to cut off any new air entry. You will notice after this second operation that the bag will form an air pocket, which is perfectly normal. The machine will then take care of vacuum sealing the bag.
