A hand or power operated machine for freezing and stirring ice cream specifically : a can rotated by a crank within a tub of ice and salt so that the ice-cream mixture in it is stirred by a dasher.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.

These ice cream freezers are the single most efficient type of ice cream freezers for an employee who will be serving ice cream directly to customers.

Blast chillers or freezers operate by blowing forced cooled air over food placed inside. These specialized freezers usually have various settings that can be selected depending on if your food is room temperature, chilled, or hot. This rapid cooling process decreases the number of ice crystals that appear on food.A typical blast freezer temperature hangs between -30 to -40°C. This is far colder than regular freezers, which tend to keep food at around 0°C. The big temperature difference means a blast freezer can freeze food effectively in under 3 hours. Where it might take anywhere from 6-12 hours in a normal freezer.
