After leaving clear instructions as to what to buy, some kind sole opted to get me a snailshell style amnps clone! It is relatively well made and I see no reason why it shouldn't do the job for cold smoking but I've hit a problem. In my minibar fridge conversion for cold smoking it will not burn for more than an hour or so before self extinguishing. The setup is as follows. 40mm hole on bottom of left wall for air intake. 40mm hole on top (back right corner) for exhaust Generator sits inside fridge where the salad drawer wow normally be found Food sitting on shelf above. I have used 40mm plastic drain pipe style tubing for the ports and each has an elbow to stop direct wind / rain from getting in. The smoker hasn't hit above 52 degrees f during the times its been burning. I am using cherry wood in the unit, in the quantities described in the booklet. I see the problem being one of 3 things. Ambient temp too low? Wood has 'issues' of some sort Not enough air coming into the unit for burning. Is there a clear way of knowing what the issue is? I will reload with some hickory tomorrow to rule out the wood issue but before I cut another inlet into the side of the mini fridge is there a best guess as to if air shortage is the problem or if it's something else? I've had a bunch of chillis and a few garlic bulbs in there and after about 3 hours of decent smoke some of the garlic is starting to take on a bit of colour and smell, the chili are still resisting it for now although there is a slight smell to them.
