So long old friend

I've been reading the excellent The Art Of Making Fermented Sausages by Marianski and Marianski that I got for Christmas. The book is a real tour de force - covering every aspect of fermented sausage production from the science behind the process, bacterial cultures, and chemical changes occurring in the sausage, to meat selection, how to rig up drying equipment and store the finished product - all in clear, concise language. It made me think of my wine cooler curing chamber and how it really needs some improvement if I'm ever going to make decent fermented sausages safely.

So, I've done a bit of soul searching and finally admitted that it isn't working out with the wine cooler (it's not you - it's me etc; although it really is you). The Peltier system just can't cope with the humidity required: the plate and fan ice up, stopping the cooling altogether. This in turn causes the temperature to rise and the RH to drop. In short the system just isn't stable; this should have been obvious given that some dehumidifiers work by using a Peltier-cooled plate to remove moisture from the air. Disconnecting or slowing the fan doesn't work (the fan is also causing case hardening of the sausages).

We hardly knew ye

I've decided to take the plunge and make a chamber from scratch using a proper fridge (not a wine cooler). Temperature and humidity will be monitored and controlled to create the stable conditions required for curing. I'm currently gathering the equipment and hope to post on my new build in the next few weeks.
