Attached are a couple designs for bulk subzero extraction using ethanol, which are featured in our new The Alchemist Resource blog site that we are launching 11-1-2017.

The first uses a mag drive pump to circulate the -50C ethanol, while the second uses air or nitrogen pressure to transfer the liquid back and forth.

Both use dry ice to chill the ethanol.
