How does a blast freezer machine work?

A blast freezer machine works by circulating cold air over the food product to rapidly lower its temperature and freeze it quickly. The machine typically has a powerful refrigeration system that generates cold air and a fan that circulates the air over the product. As the cold air circulates, it removes heat from the product and lowers its temperature. The rapid freezing process helps to preserve the quality and freshness of the food product by minimizing the formation of ice crystals, which can damage the texture and flavor of the product.
