There is a bit of discussion on another thread regarding drying and humidity.
http://forum.sausagemaking.org/viewtopic.php?t=1463Although it depends on temperature and relative humidity, a lot also depends on what size casings you are using. I am pretty new to all this myself, but have noticed that the bigger diameter the casings are, and the higher the RH, the slower the salami's/chorizo will mature/dry. I have in the past had results where case hardening was prominent. This was with smaller casings, a lower RH and higher temperature. It drys the casing a lot quicker than the inner mix and sometimes creates a void through the middle of the sausage. This is generally accompanied by a discolouration of the meat more to the grey side and I discard these, preferring not to take any chances.
I generally try to aim for 70% RH and 15�C for drying/maturing. At present my workshop is not too far away from these figure, fluctuating a bit as the nights are a bit colder than the days. I am finding that it is also helping the RH, and slowing the drying process by keeping them in my biltong box. No doubt this may change a bit as the weather warms and brings the temperature up and the RH down.
My small tutorial is very sparse but more information can be found on Len Poli's site, where he explains all the concepts and procedures very comprehensively. He also have a number of dried sausage recipes which indicate differing techniques and drying/maturing times.
