Home Made Cold Smoker

I came up with this idea of a cold smoker. 

Basically the microwave at the bottom will hold the smoking tray from A-MAZE-N.  I am going to use simple aluminum ducting to go from the microwave up to the PC case.  The aluminum ducting would snake back and forth inside the computer case and then came back out and up to the mini fridge.  There will be a PVC vale vent that comes out of the microwave to control how much air flow comes into the system and hopefully will create movement of the smoke.  If I have problem with movement then I will put a small computer fan in some were, like maybe the chimney to create some movement.

The three fans on the pc case will each have their own switch and so its my thought that I can some what control the temperature in the fridge for cold smoking.

Also if I need to I can put a small pump, reservoir, and misting nozzles in to the computer case and hopefully create some added cooling capability.

    I agree this is overlly complex when there are loads of simple solutions. My smoker is made of an old commerical fridge (all stainless inside and out) and external smoke chamber which when directly attached is a hot smoker and a cold smoker when attached to a longer hose where the smoke gets cooled due to the distance it travels. When not being used to smoke it becomes a biltong maker. One unit, one footprint no tar, no fuss. It works so well people buy smoked foods and biltong from me :)

    I use a small bar size refrigerator for my cold smoker. I make a smoke generator from a metal 15 ounce can and a small "pencil point" size soldering iron. Open the can top half way only so that you can bend it back closed. Make a hole just large enough to allow putting the soldering iron all the way into the can. fill the can with wood chips and bend the top back closed. I put the can in a small ceramic bowl so that the can is tilted to let the chips settle down to the tip of the soldering iron. This also protects the plastic liner of the refrigerator. Closing the refrigerator door around the makes a good seal to hold in the smoke. The operating refrigerator keeps things cool. The metal can smoke generator is not my original idea. This is a much simpler and easier way.

    I made a cold smoker out of an old fridge that I've been using for 8 years to make 40lbs of great smoked salmon at a time. You simply invert the fridge and make the freezer your smoke box with a hot plate.. cut a hole between the two compartments and add a baffle to distribute the smoke. cut a hole in the top for a smoke stack and add a damper to it. I made a rack that I slide dowels into which I place cookie cooling grates on to maximize the density of fish to smoke.
    The hard part was taking out all the plastic interior and replacing with tin flashing. Better to use an older fridge with metal interior.

    This is way more complicated than it need to be. The A-maze-n smoker produces almost no heat. I use mine - sitting on a brick - in a tall card board box. Smoke on a cool day or night - the temp will only go up about 10 degrees.

    You'd end up with a fridge full of tar.

    Ah I don't think so. People make fridge cold smokers all the time, it is a proven implementation.


    A microwave is built from similar materials as a fridge so I think I am ok their. The only thing I am doing different is trying to be able to get a cooler temperature which is one of the challenges in most fridge smokers when they put the A-MAZE-N smoke tray in the bottom of the fridge.

    They worse problem I may have would be getting smoke from the microwave to the fridge.

    Sure why not. I am going to disassemble it first and pull some components out before doing my drilling. The electrical cord will be removed so there is no way this microwave will ever be powered up again.
