What I have done is to use a PC Tower, with all internal parts removed. Built a metal shelf above the AMNPS (A-maze-N Smoker) leaving an opening at the back. The shelf does not go all the way back. At this point, used one the 12VDC fan from computer and mounted it so as to pull the smoke from the AMNPS up to the is shelf area. The shelf area has one to two frozen water jugs, made from empty Orange juice or gallon tea jugs. The fan forces the smoke around the frozen water and up into a 2-1/2 inch PVC pipe. From the PVC pipe it then up and into the bottom of an old 3.2 cubic inch mini fridge that the compressor no longer worked. (made a hole in the bottom of the fridge for the PVC pipe to enter.) Mounted the 2nd 12VDC fan on top the opening. This fan will draw the smoke from the PVC pipe into the fridge. On the back side of the fridge where the compressor normally would be, I remove it and all cooling coils, wiring and thermostat controls. In its place is a 12VDC battery (I used a deer feeder battery), Solar Panel, 110VAC to 12VDC converter, and the wiring for each fan. Here is my thoughts on these three setups: 1. Use Solar panel when sun is out to operate the fan/s. 2. Use 12VDC battery when sun is not out to operate the fan/s. 3. Use 110VAC converter when the sun is not out and the battery is dead to operate the fan/s. The fridge is mounted on an old BBQ stand and the PC tower is mounted to the legs of the BBQ stand. After all of this, ran a test on the fan in the PC tower, it worked, then a test on the fan inside the fridge and it worked as well. Then tried both fans, a lot of smoke. Made a final test with no fans, there was more than enough smoke to do Cold Smoking - a thin blue line of smoke came from the exhaust tube on top of fridge. Now I don't have to rely on any power source, can you believe it????? Just a note: from all of the test the smoke was definitely cold smoke. Here are some pictures: Now working on a Kegerator that my son-in-law doesn't use anymore due to bad tubing. The compressor stills works and can get down to below freezing temps. Plan on venting the AMNPS down the beer tower where the faucet is mounted as well. Plan on pushing the smoke through a tube and while at the same time the smoke from inside can be vented back up the beer tower. This would be like a two way street and there is plenty of room for both smokes to go down and come back up. Therefore no holes are needed to be drilled. Just will be needing to add racks and shelves to it and mount a temperature probe into it as well. Then will be ready to start really COLD SMOKING again. I guess one could this call it a "Smokin-Keg"? Note: The faucet will be used for decorations only.
