What is a blast freezer?

A blast freezer, also known as a shock freezer, is a type of freezer which is designed to very rapidly bring down the temperature of the contents being stored. They are widely used in commercial kitchens and in the frozen food industry for fresh produce, ice cream, pre-prepared meals and vegetables or fish.

How do blast freezers work?

When food is frozen, the water inside it crystallises into ice and the longer the freezing process takes, the larger the ice crystals formed. These larger crystals can damage materials by causing cell bursting whereby they rupture the preserved food's cells. This often ruins the quality and flavor of food produce by affecting its taste and texture. Rapid freezing however causes very small crystals to form, which prevents damage and preserves food at a higher quality. Once the food is frozen in a blast freezer it can be moved into a normal freezer for long term storage.

Blast freezers usually use blower fans which force cold air across the contents of the freezer in order to rapidly chill it. They can be equipped with trays which move in order to position foods, and often include various compartments for freezing. Blast freezers can normally handle foods at room temperature or heated as long as the capacity is not overloaded.
