Blast Chiller 


If you serve hot meals, then you will almost certainly benefit from using a blast chiller or freezer.

Blast chilling & freezing is the only way to ensure food safety and quality.

Current food legislation requires that all food must be cooled as quickly as possible.

This means that whenever food is chilled or frozen, it must be in the ‘Danger Zone’ between +8°C and +68°C, where bacteria multiply fastest, for as little time as possible.

To achieve this, a specially designed blast chiller or freezer is required. Standard refrigeration equipment just isn’t capable.

Why putting warm food in a refrigerator just won’t suffice:

The food quality is reduced by damage to the surface texture, water loss and separation during a slow cool down.

Bacteria have time to multiply before a safe temperature is achieved, potentially damaging condensation is created, which can contaminate other food.
The refrigerators’ temperature is raised, bringing other food into the ‘Danger Zone’



What is Blast Chilling?

Department of Health Guidelines state that to safely blast chill food, its temperature must be reduced from +70°C to +3°C or below within 90 minutes.


What is Blast Freezing?

The Blast Freeze process requires that food be reduced from a temperature
of +70°C to -18°C in no more than 240 minutes.


Helpful tips


Pre-chill the cabinet for 30 minutes before the first load to remove interior residual heat.

Doubling the food thickness triples the cooling time.

Don’t stack food or containers on top of or alongside one another.

Covering the food increases cooling time by between 10 and 30 percent.
