How Cold Is a Blast Freezer?

The temperature range of a blast freezer varies depending on the manufacturer, but one thing is a fact; it is much colder than your average domestic freezer.

At CRS, our range of blast freezers and chillers are designed with temperature ranges of -40°C to +10°C.

Why Are Blast Freezers So Cold?

Commercial freezers are widely utilised in the frozen food industry for temporary storage and transportation. These freezers provide extremely low temperatures ensuring optimal quality and taste preservation.

It is well known that freezing reduces the growth rate of bacteria significantly, which in turn reduces the risk of contamination and potential harm to consumers. The lower the temperature, the better.

Hazard analysis and critical control points

The rate of cooling or freezing is also a crucial aspect of blast freezers. The HACCP have set legislation stating that food needs to be cooled at the quickest possible rate post-cooking. If a freezer takes too long to freeze cooked food, the risk to consumers is heightened due to bacteria growth.

The low temperature and rapid cooling time contribute to better-quality produce. Provided food handling is safe, and freezing begins immediately after cooking, minimises contamination, and encapsulates freshness.
