A contact freezing apparatus comprises a plurality of freezing plates in which freezing medium is circulated in the interior, movably connected at a predetermined interval in an elevational direction, first elevation cylinder for raising the uppermost freezing plate until the respective plates are suspended and lowering the same so that the adjacent plates make contact with freezing pans, second elevation cylinder for raising or lowering at least one specific freezing plate in the state that respective plates are suspended to dispose the lowermost freezing plate at a predetermined position in height, and engaging or disengaging mechanism for engaging the specific plate with or from the second elevation cylinder in response to the position in height of the specific freezing plate. Thus, a worker can load or unload the freezing pan on or from the freezing plate at a predetermined position in height. |
