How to vacuum seal Liquids?

2 mn read

Yes! It is troublesome. But, there are different methods to vacuum seal liquids like the freeze method, ice cube method, paper towel method, and the vacuum chamber sealing method. Among all the methods, the vacuum chamber method is the most commonly used method.

In a vacuum chamber sealing method, internal pressure in the chamber is minimized at the same rate as that of the pressure inside the vacuum chamber. In this way, the liquid remains inside the bag instead of spill out of the opening.

One thing to consider is that liquid is supercooled before using the vacuum chamber. The reduction of pressure inside the chamber, causes the liquid to boil out of the bag. The main advantage of this liquid sealing method is that it requires no waiting time between the seals, however, it requires commercial expensive equipment.
