A drum dryer like you use for clothing sounds built to take water out of these things (with grates smaller than the pellets of course).

  Noisy as hell though. Also, how robust are the pellets? Tumbling them may create a lot of dust. Damp dust would be tricky to control. I used to have to dry silica gel bags. We'd put them in a temperature controlled oven for a few hours, it'd ramp the heat up and fans would pull air through. That worked quite well, but was only for small quantities. I guess you could have many mesh racks with heating at the base (or even through the mesh) and fans at the top to extract moist air. Drying that air and re-using it would handy.

  The stuff is fragile (or at least the 5nm molecular sieve type)- if you shake it too much you make dust which blocks the pores
