In the food industry, freezing is the most important aspect. We buy so many foods from the market which need to be kept in the freezer. These days, there are so many frozen foods available in the market and people love them as they make their life easier. You just have to keep them in the freezer, remove them when you want to use them.

You have to either fry them or cook them slightly and you are done. Your meal is ready in no time. This is the reason people prefer to keep frozen foods at home. There are so many different types of freezing equipment and freezing technologies available in the food industries. One of them is the tunnel Freezers.

What are Tunnel Freezers?

Tunnel freezers are specialized freezers and they can freeze large quantities of products in a very short period of time. When a product is frozen in the tunnel freezer, the product is free of clumps and also does not stick together. For example, if you are freezing peas, they will be stuck together when you take them out of the normal freezer. But in a tunnel freezer, all the peas will be separated from each other.

Individual Quick Freezing

It is also known as Individual Quick Freezing. Tunnel freezers are usually used in food industries that want to freeze large quantities of products in a short period of time. These are specially the industries which are involved in manufacturing and preserving of meat, processed food and seafood.

The main benefits of the tunnel freezers are that they provide you a high quality of products after freezing and also they are more energy efficient. Now the main question is how do the tunnel freezers work?

How do they work?

Tunnel freezers use cryogenic gases such as carbon dioxide or nitrogen to freeze the food. The food items which are fresh are placed on a conveyor belt and then that conveyor belt carries these food items to the freezer. In these freezers, there is an injection system which has fans and it circulates gas and chilled air which ensures that the food items are frozen quickly.

After this whole process is completed, these food items are shipped to different places like grocery stores, warehouses, restaurants, cafeterias, hospitals and many more. We cannot even think of the way or the equipment these products are frozen when they reach us. There is a lot of work involved behind keeping them fresh and frozen until they reach us.


If you think that buying a tunnel freezer will be beneficial for you, then you should do your full research before buying one as there are many different types of tunnel freezers available in the market with different types of belts. Some of the examples of these belts are net belt tunnel freezer, solid belt tunnel freezer, super-jet mesh belt tunnel freezer.
