    • This invention is directed to an apparatus for freezing an article under cryogenic conditions which comprises a housing encompassing an entry port, a freezing station, an exit station and an exit port being at a greater vertical elevation than the entry port and freezing station. In connection with the housing, there are means provided for transporting the article to be frozen sequentially from the entry port, entry station, through the freezing station, and then to the exit station, preferably at a rate of travel which increases as the article is being transported through the exit station. A connection is made to the housing permitting the introduction of a cryogen into the freezing station thereby maintaining such station at a cryogenic temperature.
