How Does Vacuum Sealer Work?
You have known many types of vacuum sealer, but how does it work?
Haste makes waste, don’t be hurry. Let’s discover its structure first!
Structure Of Vacuum Sealer
The vacuum sealer consists of two main parts: a pump and a heater.
A pump is used to pump vacuum into the bag. Depending on your needs and purpose of use, you can choose pumps with different capacities.
Another main part is the heater. This part is used to seal the containing bag after vacuum injection.
Besides the two main parts, the vacuum sealer also has other components such as control panel, machine shell, solder bar, etc.
Normally, a vacuum sealer can be made from hard plastic, glass or metal depending on manufacturers and it can operate with 220 volts or 380 volts power sources.
Last but not least, for using the vacuum seal, suitable containing bags are needed. Depending on the type of vacuum sealer you use, you will have to choose the appropriate bag.
The operating principle of the vacuum machine is relatively simple. As we mentioned above, the two main active parts are the pump and the heater.
When you put the containing bag in the correct position on the machine, the pump unit will pump the vacuum into the bag to remove all the air.
This process usually takes about 15-25s depending on the type of machine and the size of the bag which usually for home use. With larger containing bags, industrial vacuum sealers are needed, and certainly, it will take more time to finish the process.
After the bag has been pumped enough vacuum, it will be the sealing bag process. Typically, this step will be completed automatically. However, for a handheld vacuum sealer, the user must self-seal the bag with tape or other adhesives.
