I purchased a Bradley 4 rack digital a couple of years ago that I've used for bacon, garlic sausage and hot smoked salmon with good success. Where I live the winter temps routinely get down to -30 C with -10 C being average in the winter. I'd like to try cold smoking some salmon on warmer winter days when its between 0 and -10 C. Considering the temp would I still need to use a cold smoke adaptor or would the cabinet stay cold enough without?
The cold smoke adapter would probably be a good idea. I'm in Alaska and I use mine frequently. I smoked cheese with an ambient temp of 28ºF and maintained 75ºF in the Bradley without the adapter. This is the very warmest I would smoke cheese or bacon. I've used the adapter to smoke bacon in the spring and summer and it does a fine job and maintains a true cold smoke temp. However, this is just my humble opinion.
What Doug said :) I'm in Nova Scotia use it year round.
