Then will finish drying my semi dry sausage?might work for the smaller ones, but you may get case hardening on the 2 1/2" dia. casings. 41% humidity is low for drying. The bag method is for stuff that has already been dried by smoking to about 15-20% moisture loss.
Might try making a small batch, say 1-2 links and do a test to see if it works. I would definitely add either a cool mist humidifier or a large tray of water with a towel suspended hanging over the water with the bottom of the towel touching the water.
