ABSTRACT:
An apparatus for reducing temperature of items includes an enclosure having an inlet and an outlet for the items within the enclosure; a conveyor for conveying the items within the enclosure from the inlet to the outlet; one or more delivery nozzles positioned to deliver gaseous cryogen and liquid or solid cryogen at supersonic velocity to the items on the conveyor. The apparatus delivers supersonic gaseous cryogen and fine liquid cryogen droplets onto the surface of food items to cool or freeze the food items.
