How cold does a blast freezer get?

A blast freezer is capable of reaching extremely low temperatures to rapidly freeze food items. Typically, a blast freezer can achieve temperatures as low as -40°C to -60°C or even lower to -80°C, depending on the model and specifications. These ultra-low temperatures allow for swift freezing of food items, preventing the formation of ice crystals and preserving the quality, texture, and flavor of the products.
