Air blast freezing is the process of taking a product at a temperature (usually chilled but sometimes at ambient temperature) and freezing it rapidly, between 12 and 48 h, to its desired storage temperature which varies from product to product (e.g. fish = −20 °C, beef = −18 °C).
Can you store food in a blast freezer?
Commercial kitchens, for example, use blast freezers to safely store cooked food and meals, leftovers, confectioneries, dairy products, seafood and meat. ... Blast freezers can normally reduce food's temperature from 70 degrees Celsius to -18 degrees Celsius within 4 hours.May 13, 2016
What are the benefits of a blast freezer?
Blast chillers and freezers work by rapidly decreasing temperatures of food products. Rapid cooling minimizes loss from evaporation compared to a normal cool process (like within a refrigerator). In addition, rapid cooling helps decrease the size of ice crystals that form in food when it is cooled and frozen.Feb 28, 2018
