In order to satisfy their customers on time, most restaurants stock up on food supplies. These various food products are preserved to maintain their nutritional value. The only modern device capable of achieving this feat is the vacuum machine. It is a food packaging machine that, in addition to helping you save money, ensures proper preservation. This article aims to help you understand how this machine works so you can use it daily.
The usefulness of a vacuum machine
In the past, salt, smoke, and cold were commonly used for food preservation. Indeed, any organic food left exposed to the air becomes infected with microbes and begins to decompose after a while. This is how people resorted to these various methods to keep food in good condition for a long time.

Today, in this contemporary era, the best preservation method is to prevent food from coming into contact with ambient air. This helps to stop the development of bacteria or microbes and thus increases the shelf life of food. The vacuum machine is a device that blocks the entry of oxygen and germs responsible for food fermentation into the sealing bag. It is extremely useful for food preservation at home and in restaurants. Thus, everything is explained here in this article to help you easily use this marvel.

Generally, there are two types of vacuum machines:
- External suction vacuum machine: This is the most commonly used, as it is suitable for packaging solid foods. You can easily preserve all your food in embossed vacuum bags. It has a small motor and is therefore suitable for small productions.
- Chamber vacuum machine: This is recommended for professionals. Unlike the previous one, it supports all vacuum bags for food preservation. With a high-power motor, this machine is suitable for large productions and for preserving both solid and liquid foods.
Depending on your needs, do not hesitate to acquire a vacuum machine to avoid throwing away food in the future due to poor preservation.
The process of vacuum sealing food
The very first rule of preservation is to ensure that the temperature of the food is very low before vacuum sealing. Indeed, hot food or food still emitting steam cannot be preserved. To vacuum seal food, simply follow these steps:
- Check that your vacuum machine has a clean sealing bag without wrinkles;
- Place the food (at very low temperature) in the sealing bag;
- Insert the bag containing the food into the vacuum machine.
The machine will then extract all the oxygen contained in the storage bag with its internal air vacuum before proceeding to seal the bag to prevent air from entering again. After that, you can remove your storage bag and wait a while before repeating the operation for preserving another food item.
