Using a Blast Freezer vs. a Slow Freezer

If your business handles and ships food products, you know the quality of frozen food matters. You also know it can change quickly depending on how it's frozen and stored.


But which is the best method of freezing food, and how does it work? Let's look at the blast-freezing process and compare it with other, slower freezing methods.


How Does Blast Freezing Work?

The blast freezing or flash freezing process works by blasting food products with cold air and sucking the hot air out of them simultaneously. This process occurs in a blast-freezing chamber that facilitates the exchange of hot and cold air. It uses refrigerant to remove heat from the chamber's air and turn it into gases that exist outside of the food products they just left.


The blast chilling process repeats, pumping cold air over the products and drawing away the hot air until the products reach -18 degrees Celsius (-0.4 degrees Fahrenheit).


Other Quick Methods of Freezing

Blast freezing cools products quickly, but it's not the only way to freeze them.


How Slow Freezing Methods Work

The methods described above freeze products in a few hours or a few days. But slow freezing takes several days or weeks to cool frozen foods. Slow freezing usually occurs in storage freezers where food products sit on the shelf and gradually cool.


While this process sounds easy, it gives your food products more time to grow bacteria or let large ice crystals form on their surfaces. It also allows your food to lose many of its nutrients.


The Benefits of Blast Freezers

When you cool your frozen foods down in a blast freezer, you reap a variety of benefits.
