I have just entered the world of cold smoking! Started small with a home made cardboard box, old cooling rack on two dowels nearer the top. Bought a cold smoke generator, the round snail design type. Using fine oak chips. I tried using tealight to get smoke going, but found it went better using my small cooks blowtorch. All is fine for a while, then the smoke dwindles and stops completely.
I wondered if air flow was the problem, so have waited for a windy day, which today was. Delighted to have steady stream of smoke for a whole hour, then it went out yet again. Relit after a while, another hour of smoke the stopped. At that point it rained, so experiment over for today.
I have raised the generator on an upturned roasting tin, so it is fairly level with airflow holes. 3 x 2 cm squarish holes on one side, 1 hole on opposite side and 2 similar on the back.
In the top I have a toilet roll chimney!
Any help will be appreciated.
Many thanks
Jo
