May I suggest you take the salami out of that beer fridge and put them in a regular household fridge. The reason they are not drying is because the beer fridge does not have enough air circulation which is necessary for drying. Its kind of like if you hang wet clothes in a closet, they will not dry very fast. A regular household fridge has a circulation fan that keeps air moving around and helps drying.
Just my 2 cents. That beer fridge is good for keeping beer cold, but that’s about it.
