Dave,

If you search the cryonet archives you'll find a piece I did on creating liquid

nitrogen, the making of dewars that had less venting problems through recooling 
and

recirculation and the availability of off-the-shelf liguid nitrogen making 
machines

and recoolers. There you may find the URL for the company that makes the LN 
making
and recooling machines. They are reasonably priced.
