When deciding on a freezer room and blast freezer it’s important to know the options available and how they best serve your business. This can greatly impact how you store your products and whether or not they meet the regulations that apply to them.

In fact, when comparing some freezers, they may not be as similar as they first appear. So how do you know what freezer you need and why you need it? Depending on your business, you may require a freezer room, a blast freezer or both, and this is why.

Freezer room

A freezer room is designed to store a range of products and materials at subzero degrees which will prolong the lifespan of food. However, unlike a blast freezer, a freezer room cannot freeze products at a rapid rate. You might also want to keep in mind that freezers are unsuitable for many kinds of products and materials, including those that will damage in below-freezing temperatures. Products that are to be used imminently, with no time for them to defrost are also not suitable for freezers.

There are a wide variety of freezers to choose from and most have varying temperature controls. At Burton Industries there are two types of freezers. One ranges from 0 degrees to minus 15 degrees and the other can store products at minus 15 down to minus 20.

The freezer panels need to meet certain criteria and standards such as:

cyclone tested
lightweight
strong
easily mounted
demountable
vermin proof
hygienic
insulated

The freezer panels can reach a maximum continuous surface temperature is 76.7°C, without affecting its freezing properties.

So how does a freezer differ from a blast freezer?

Blast Freezer

A blast freezer cools its contents quickly, rapidly dropping the temperature. Flash freezing in a blast freezer is one of the safest and most effective ways of preventing bacterial growth.

Blast freezers hold temperatures between minus 28 degree down to a chilly minus 40 degree. As a result, the ice crystals that form in the process are small, causing less damage to the products. This captures the products freshness and nutritional value.

Examples of foods stored in blast freezer are:

Frozen vegetables
Ready meals
Meat
Poultry
Gelato

Various sizes of blast freezers are often required as they are used throughout the entire food industry process. As a result, blast freezer panels can be manufactured for any application, whether it’s required as an in-store blast freezer, an industrial walk-in blast freezer room, or blast freezer panels for a truck.
