Title: Homade cold smoker
Post by: topguntransfer on June 11, 2014, 06:37:33 AM
This was easier than I thought it would be. The most expensive parts were the electric/gas dryer vent duct work and the box that my wife got from an online order!!

Some flashing I had laying around. I rolled it up and put it in the smoke inlet and let it expand. Marked it and cut enough for overlap and used some industrial spray adhesive to make the duct connector.

Pulled the foil back. Cut it about every1/2" or so to make lay out flat. Coated the flashing with adhesive and folded the foil up against the duct. Put the leading end onto a flat piece of cardboard the glued that to the box. Just felt better about having a little reinforcement.

The ambient temp. was 94F. The 101F was as high as the tower got. I think this will be helpful when smoking at the lower temps.

Cinder blocks used just to keep things tight. Sealed box with cellophane shipping tape. It can be cut away instead of pulling and tearing the cardboard. All of the flaps were glued except the one with the label. I used a smaller bowl for the biscuits, as I will use the original in the tower for dripping and "flavored water". The generator is producing full smoke at this point. You can see a little leakage at the tower and some between the box and generator.

I hope some one can benefit. I don't know how long it will last. I will post about that and any problems. Please feel fre to comment or ask questions. I would like to thank Habanero Smoker for his help and ideas.

That looks pretty much like my first cold smoke mod. I think my box had some different labels on it though. ::) best to keep it out of the rain. ;) ;)

You might want to get a thermometer that will more accurately monitor the temp inside your tower.  At 101F you are over the high end of what some folks consider cold smoking.

Nice job on the cold smoke set up.

Regarding KyNola's comment about the temperature being on the high side, it looks like Topgun has quite a bit more dryer vent that could be extended.  Stretching out the vent a bit might be all it would take to drop the temp a few degrees, if he wants.

Yep the further away the generator is from the tower the cooler it will be.  :)

Gonna be hard to cold smoke anything on a day when the ambient temp is 94F no matter what you do! I would agree with Kynola, a maverick or some other type of thermometer would be in order to get a more accurate tower temperature reading.

You have a nice setup. As others have stated, moving the box further away from the cabinet will help. Looks like you have plenty of shade. Smoking during the cooler parts of the day, such as the late evening or early morning hours, when it is cooler will help.

The leakage from the top of the cabinet is minor, but if you want to attempt to make the seal tighter, the next time you use the cabinet, after it has warmed up and the seal is more flexible, gently pull and stretch the seal at the area it is leaking. This sometimes improves the seal.

Thanks Habanero, and every one. The controller is as far away as I could do for now. I will have to make some extension cables for the thermocouple and the heat strip. Mostly wanted to see if I was on the right track. It was in the hottest part of the day and I don't mind smoking at hours that are conducive to good smoke. What else have I got to do "Watch TV"? I don't think so.
Thanks again everyone. I will keep you posted on the success of the box.
Happy Smoking.

Another thing that I do for cold smoking is keep a few 1/2 gallon milk jugs of ice in the freezer. If my cabinet temp starts creeping over 90F I put one or two jugs of ice in the V tray.

I should clarify that when I say cold smoke and 90f I am referring to smoking cheese. 90 is probably to high to be considered a safe temp for cold smoking meat.

Topgun, back in the olden days I remember that my Dad used to "paint" corrugated boxes that were going to be used for storage with shellac to help prevent moisture absorption and greatly extend the life of the box.  Wonder if this would work with your "cold smoker" box.  Since shellac is a natural product, I'd think that the toxicity would be pretty low if you allowed it to dry really well for a few weeks.  Or, just didn't coat the inside of the box.  The solvent used with shellac is alcohol.  So, it's not like you have a petroleum based carrier for the shellac.  And, alcohol is a solvent that at least one of our most senior members has recommended as a solvent to use for cleaning puck burners and the like.  So we have some history of using alcohol in conjunction with our smokers.

It may be more convenient to make a Bypass Plug. Then you won't have to deal with any cables.

Or, if you are electronically challenged, like me, you can order a bypass plug from Yard and Pool.  There has got to be something you need from them.  You just don't know it yet.   :)

Or, cut the thermocouple wire and splice in a section of small gauge lamp cord.

Instead of using a cardboard box which will not have a long lifespan. Try one of these smaller washtubs from a ranch supply store. They will work just fine. They will also help get rid of some of the heat.

Rather than make your own start collar, you can find these at your local big box store. A perfect match for Kirby's washtub.

Thanks all. Very good ideas. I was planning to throw a gallon freezer bag or 2 inside the tower. Also I have made a heat exchanger for the duct work. I will probably try in a day or two, to see what works best. I am an electrician by trade. I cut the power cord in half and added about a four foot extension in between. I have some thermo couple extension wire and will just make a one piece as long as I need.

It's early in the morning here and I may be half asleep but why do you need the bypass plug. When I smoke with my PID I just run the SG and the cabinet runs off the PID. Like two separate systems. Can he just not plug the cabinet in and run the SG???

I do not think a digital smoker will operate unless it has something plugged in to give a temp reading.

QuoteI have some thermocouple extension wire and will just make one piece as long as I need.
Just so you are aware, the Bradley does not use a thermocouple it uses a thermistor to get temps. So T/C extension wire is not needed I normally use a section of two wire shielded cable 20-22 gauge is plenty big enough. The shield is not needed but we use this cable at work all the time and I can get small pieces for free. :) But any small ga. two wire cable will work. Also in case you ever do get a T/C and plan to use the extension cable you need to match the extension cable type to the T/C type to get an accurate reading. For example Type K T/C will use type K extension wire which has a yellow outer jacket and red and yellow wires inside. Type R has a green jacket and red & black wires. Type J has a black jacket and white & red wires. The red is negative.
Hope this help some. :)
