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. The extremely low temperatures these freezers provide ensure optimal health and safety in addition to 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 an extremely important aspect of blast freezers. In fact, the HACCP have set legislations stating that food must 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 very low temperature and rapid time to cool both contribute to a better-quality produce. Provided food-handling is safe and freezing begins immediately after cooking, contamination is minimised, and freshness is encapsulated.

This has made our commercial freezer range a popular choice for many businesses in the food and drink industry, ranging from ice-cream, ready meals, meat, vegetable and fish.

Our commercial freezers feature the latest cold storage technologies to comply with all food-related standards and to ensure optimal quality and safety of your products.
