Abstract: A method to freeze items includes placing an item to be frozen in a freeze chamber of a blast freezer and freezing the item. The method includes applying a pulsed electrostatic field to the item for one or more time intervals while freezing the item. The method may further include, in response to application of the pulsed electrostatic field to the item: alternately pulling charged particles within the item in opposing directions and alternately accumulating charges on a surface of the item opposite to the pulsed electrostatic field. The method may further include creating microscopic ultrasonic vibrations on the surface of the item in response to the alternate pulling and accumulating. The method may further include transmitting the microscopic ultrasonic vibrations internally into the item to inhibit formation of ice crystals within the item during the freezing.
