Blast freezers (or, flash freezers) can save you some serious time. Full plates of food can be prepared before a big rush or an event, frozen in a blast freezer, then brought to normal temperature in a short amount of time – preserving all of the taste, texture, and flavor. Brands of blast freezers include Electro-Freeze, Taylor, Delfield, and Emery Thompson (made in the USA!). But how does a blast freezer work?
When food is frozen, the water inside it crystallizes. If freezing takes place at relatively warm temperatures, the ice crystals which form will be large. In a blast freezer, the extremely cold temperature promotes very rapid freezing, which creates small ice crystals. The smaller the crystals, the less damage to the food, as large crystals can rupture cells. Once the food has been frozen in a blast freezer, it can be moved to a more conventional freezer for storage, as long as the freezer stays cold enough to keep the food frozen.
Many blast freezers operate with blowers which force chilled air over the food in the freezer to cool it down rapidly. Others may operate differently, depending on the design. Blast freezers can be equipped with movable trays for positioning foods, and they may also include an assortment of compartments for freezing. The freezer can usually handle foods which are chilled, at room temperature, or hot, as long as it is not overloaded; too high a volume of hot food, for example, can cause the temperature in the blast freezer to rise.
There’s another advantage to blast or shock freezing, beyond the preservation of the integrity of the food. Extreme cold inhibits bacterial growth, which means that if food is handled safely and then placed immediately in the freezer, the likelihood of contamination is very low. This increases food safety, making such freezers popular in commercial food preparation to reduce the risk to consumers.
