Blast Freezers are designed to swiftly lower the temperature (-20°C to -40°C) in a controlled environment. They are mainly used to store food items such as cheese, paneer, curd, seafood and meat. Powered with clever cooling technologies, they can be helpful in processing plants that require storing food products.

Before you contact a blast freezer rental service for your needs, it is important to know how they work and how they can benefit your line of work. These freezers vary depending on your specific food industry, but their overall functionality remains the same – preserving the quality, flavour, and texture of your food.

In this blog, we will explain how blast freezer containers work and their benefits in the food storage industry.

How Do Blast Freezer Containers Work?

A blast-freezer container works by rapidly freezing perishable goods using powerful refrigeration systems and high-velocity fans that circulate ultra-cold air (often -20°C to -40°C) throughout the insulated container, quickly pulling heat from the products and bringing their core temperature down from around 50°C to -18°C or lower within hours. This fast freezing prevents the formation of large ice crystals, preserves texture, flavour, and nutrients, and minimises bacterial growth, making it essential for industries like seafood, meat, poultry, and ready-to-eat foods while also serving as a portable solution for cold chain logistics and storage.

Benefits of Blast Freezer Containers

The following are the advantages of blast freezer containers in the food industry:

Easy Transportation

Blast freezer containers enable easy transportation of your food items from one place to another. This can be really helpful in industries such as meat production and seafood. In the meat production industry, sometimes the slaughtering takes place at a different facility from the packaging. In such a scenario, preserving the raw items becomes crucial, especially for long transportation routes.

While in the seafood industry, the fishing takes place near the coast, and then they are transported to another place for washing and packaging. In such situations, you can even consider a blast freezer refrigerated container on rent.

Freshness Preserved

Blast freezer containers are also vital in keeping food items fresh in industries like meat, seafood, dairy, and baked goods. They are better than regular freezers as they can lower the temperature rapidly and thus halt the formation of large ice crystals, which can cause cellular damage to meat cuts.

The structure of baked foods like bread and pastries can be maintained by keeping them fresh inside a blast freezer container. In the seafood industry, deterioration and unpleasant odours can be prevented by keeping items in a blast freezer container.

Extended Shelf Life

As a business, you would definitely not want your food items to get spoiled. By blasting & storing them in blast freezer containers, you decrease bacterial growth and enzyme activity inside them and maintain food safety for an extended period of time.

Conclusion

As you can see, the benefits of using blast freezer containers in the food industry are significant. You can even get a used reefer container if you don’t want to invest in a new one, as they are equally useful and efficient.
