Can you put liquid in a vacuum?
Do you want to preserve your soups, sauces, marinades or fruit juices? Vacuum sealing liquids is the best way to extend their shelf life and avoid freezer burn.
However, it's also the most delicate operation: with an unsuitable machine, the liquid can be drawn into the pump, potentially causing irreversible damage. In this article, we guide you toward the right solution depending on your needs (home or professional use).
Option 1: For Home Use (Vacuum-Sealed Containers)
If you have an external vacuum cleaner (the classic model where the bag remains outside), you cannot put liquid directly into a bag (unless you freeze it first). The liquid would be drawn in before the air.
The solution? Rigid boxes. The box is connected to the machine via a hose. A vacuum is created inside the box, without the risk of liquid being sucked in.
Vacuum Sealed Boxes (The Zero Risk Solution)
Compatible with all our external suction machines, these boxes are perfect for storing soup in the fridge or marinating meat in 15 minutes flat.
They are infinitely reusable, dishwasher safe and crush-resistant.

For restaurants, caterers and butchers who need to package sauces in sachets for sale or storage, a Bell Machine is absolutely necessary.
The entire sachet is placed INSIDE the tank. Because the pressure drops everywhere simultaneously (in the sachet AND in the tank), the liquid doesn't leak out of the sachet. This is the only professional method.
The Compact Bell Machine (30cm)
The ideal entry-level model for professional kitchens. With its deep tank, it accommodates soup or sauce pouches up to 30cm wide.
Power: Pump 10 m³/h - Vacuum to 99.9%.

The plus: Very deep tank for large bags.
