Sounds like a bucket with activated charcoal in it would work. Lay the bucket on its side and put some holes in the bottom of it. Put a piece of screen down and put in charcoal, then put a fan on the open end of the bucket and have it blow air out through the charcoal…out a window. Like what @MotherTeresa mentioned, but without ductwork…
…
The other option you have is to dry it the old school Indian way…outdoors for a day or two, and then wrap it tightly and bury it…the south asian cure method. @Gugumelo can explain how they do it in Brazil, or asking Fullpower selections or Irraznig, they could help. @Comacus has done it too…
How would someone make activated charcoal? How is it different from biochar?
