Blast freezer

Blast freezing works by freezing food so quickly that the water molecules inside don't have a chance to damage the food itself. When water freezes at or just below 0°C it tends to freeze in a lattice-type pattern. This pattern then forms into pure ice crystals in the cells that make up the food.Simply put, a blast freezer is just a freezer which is very cold. Blast Freezers are sometimes referred to as shock freezers. The idea of this type of freezer is to very rapidly bring down the temperature of (usually) foodstuffs or fresh produce, freezing them very quickly.The difference between a freezer and a blast chiller is that a freezer holds food at below freezing temperature while a blast chiller cools food quickly by blowing cold air over the food product and gradually dropping the temperature in the chamber.
