They have become the most commonly used equipment in almost every kitchen. From personal kitchens to corporate restaurants and grocery stores to food manufacturers, thousands of people have realised the benefits of these machines and are using them in their everyday lives. However, having a vast variety finding the best one for yourself can be a challenge. Therefore, it is essential to acquaint yourself with some basic information about Cryovac machines. 

The Basics

Cryovac machines, also called vacuum sealers, are ideal for packaging various foods. The food you see in grocery stores is packaged this way. Whether it is beef jerky, potato chips, salmon steaks, dried fruits, or any food items sold in packages, one may use vacuum sealers. And as the name suggests, vacuum sealers remove or replace natural air (which includes life-giving oxygen), making it nearly impossible for bacteria to grow. 

There are two main types of sealers used for packaging food: chamber and external vacuum sealers. While in the case of beef jerky, 99.99 per cent of the air is removed, in potato chips, natural air is removed and replaced with an inert gas like nitrogen. This is because items like potato chips are so fragile that removing 99.9 per cent of the air would damage the product. And although both machines are used to remove air, they have different purposes and are used for various products. 

With an external vacuum sealer, you need to place your product in a bag and place the package’s open end into the sealer. The sealer will remove the air and seal the open end, preventing air from re-entering the bag. However, external sealers cannot be used with delicate products like potato chips. In contrast, chamber machines are commonly used for industrial packaging. In the chamber sealer, the product is placed in a bag, after which the entire bag is placed in the chamber. And once the air within the chamber is removed, the atmosphere within the chamber is returned to normal. The sealed bag is now vacuum packaged and ready for sale or storage.
