Document Type and Number:
Japanese Patent JP2977896
Kind Code:
B2
Abstract:
A cryogenic apparatus for quickly freezing droplets of liquid product is disclosed. This apparatus employs cryogenic liquid, typically liquid nitrogen, flowing along a ramp or sluiceway to freeze a product. The product is kept in the cryogenic liquid for a relatively constant dwell time. The ramp or sluiceway is contained within an insulated vessel to preclude the cryogenic liquid from evaporating and to retain any spillage. The ramp or sluiceway is preferably spiral shape so as to allow for a maximum length run with the insulated vessel.
