In the case of sous vide cooking, the vacuum sealer helps in clearing the atmosphere surrounding the food and then acts as a sealer tightening the food cover. You can start the cooking operation afterwards. It is most suitable for solid foodstuffs but not for liquid or water like the soup or vegetables as in the process of clearing the surrounding liquid or gases also removes or clear out the liquid. So, it is not suitable for liquids as the vacuum seal does not perform the operation of a vacuum.
There are machines which can perform vacuum liquid operation but does not come cheap. The chamber vacuum works by eliminating the air inside the chamber. Both the internal and external pressure can be constant by the placement of a bag containing liquid in the chamber. This will enable it to be able to vacuum the sealed bag containing liquid.
