blast freezing temperature range
Rapid freezing creates small ice crystals and the smaller the crystals, the less damage to the food. Blast freezer temperatures typically range from -20 degrees to -40 degrees Fahrenheit and air is circulated to further speed the process.Extreme cold inhibits bacterial growth, which needs to be avoided to ensure food safety.apid freezing creates small ice crystals and the smaller the crystals, the less damage to the food.
