ABSTRACT:
A cryogenic freezer having an insulated cabinet forming an interior vessel with a bottom and sloping sides. A shallow liquid nitrogen bath is maintained in the vessel at a predetermined level. A conveyor assembly having a medial portion shaped to conform to the profile of the vessel is pivotally mounted at one end so that the medial portion is submerged in liquid nitrogen. An endless conveyor belt is mounted on the conveyor assembly by means of support rollers and guides to maintain a tensioned relationship. A jack is provided on the conveyor assembly to rotate the assembly about its pivot. An exhaust system is connected to the cabinet to remove evolved nitrogen gas.
