We recently returned from Catering a Film Shoot at a motion picture studio here in Utah. Our kitchen trailer was parked outside of the woodworking shop where about twelve carpenters manufacture stuff for movie sets, furniture, etc. Although we were only required to feed the cast & crew, one morning I had food left over at breakfast and decided to offer to feed the carpenters rather than let the food go to waste. When they finished breakfast the lead carpenter came out to the kitchen and wanted to know where I bought my ham...he said it was the best ham he had ever had. I told him that I "made" the ham using pork loin that I cured, cold smoked first in a cardboard box, and then hot smoked in my smoker. Well to make a long story short, we went into the "let's make a deal" mode and he offered to make a cold smoker for me in return for a ham. After giving him the inside dimensions that I wanted from memory (I remembered the racks were 14" square)but I wanted it deeper, 17", to accommodate a set of jerky racks that I had previously bought from Cabela's. Two hours later he came back with this "thing of beauty"


Unfortunately I couldn�t tell him where the entrance hole needed to be cut on the bottom so he told me to apply some food coloring to the chimney of my hot smoker and carefully locate the cold smoker where I wanted it to be. I did that, leaving enough room on the back to be able to reach the thermostat control. I used a hole saw like you would use to install a door knob to cut the hole. The dark piece of wood on the top of the down swinging door is the handle, contoured on the back side to grip the door. The door also serves as a loading shelf...I use a length of dowel
to support the door in the horizontal position.



After cutting the entrance hole I applied eight coats of verathane, lightly sanded between coats, because this puppy is going to live outdoors with my smoker underneath it....rain, snow or shine. By pure luck the cover that came with my smoker fits perfectly over the cold smoker and extends far enough down to protect the thermostat on my hot smoker. I�m not worried about the durability of the stainless steel below because I routinely treat it with a product called �sheila shine� designed specifically for stainless steel.



I chose jerky for the maiden voyage. The jerky turned out perfect, drying slightly over a period of about three hours (pellicle?) And the cold smoke seemed to impart a milder, less bitter hickory flavor prior to hot smoking at 170 degrees. I didn�t want to �cook� the jerky, just dry it out to the texture that I prefer.



I'm really happy with this cold smoker. The plywood that it's made of doesn't conduct heat so it stays at 50 degrees internal, no ice to worry about and manage, a convenient shelf for loading and unloading, and a place to store all my BBQ "stuff" when I'm not using it. One thing that did supprise me though was the amount of moisture accumulation in the box...I guess it should't have now that I think about it. I'm glad now that I applied varathane on the inside of the box because before reading the label on the can I was afraid of imparting a chemical flavor.

To reduce the amount of moisute in the box, try raising the box, above the smoker by an inch or two. Directly over the hole of the smoker means that everything goes directly into the smoker box, including humidity. And of course the humidity of the meat itself.

Now me, I'd probably add a convection fan to move the smoke around a bit.
SmokinOkie...I will try your suggestion about raising the box because that's what I did when I was using cardboard, only I did it then to keep the box out of snow so I could perhaps reuse it. The box would disintegrate either way from the moisture inside or the snow on the outside. Good suggestion, I will definately give it a try. The convection fan idea is also great..we must be on the same wavelength. I called CampingWorld earlier today and found that they had an inexpensive, battery powered, plastic fan designed to improve the cooling in RV propane powered refrigerators. I've got a couple of large pork loins curing right now so I'll try both approaches in about ten days. Thanks for your help Russ

The cold smoker looks great but I think you need to put a vent in it for air circulation. Ideally the vent should be below where the smoke enters the chamber. The way you have the smoke entering the bottom won't allow this. What I'd do is drill the entrance hole in the back of the unit maybe six inches above the floor and pipe the smoke in there. You could put a vent in the front just above the floor.
BR...Thanks for the suggestions, I appreciate them. The problem that I'm faced with is that I can't change where the smoke exits the "hot smoker",that's the design of the unit, so to re-route that smoke to the back of the "cold smoker" would be a plumber's nightmare, not to mention the "Rube Goldberg" appearance. I think what I'm going to try is a combination of what you suggest and what Smokin'Oakie suggested, that is to raise the cold smoker on wood furring strips to allow circulation from below (the entrance chimney from the hot smoker is 2 1/2 times smaller than the one that I cut in the cold smoker). The hot smoker chimney is a short pipe threaded nipple so if I extended that, into the cold smoker, wouldn't I achieve the same "convective" effect? The next thing would be to try the little cheap plastic battery driven convection fan available at RV supply stores and "pressurize" the cold smoker. Whaddayathink? Confused

Chateau - I love your design for a cold smoker box and will be building my own this weekend. I ordered a case of side meat to cure for bacon and am anxious to make some maple smoked bacon. Has the verathane you finished the inside of the box with left any lingering odors? Did you season the box before using it on meat? You only have 3 shelves. Are you planning on adding more? Besides raising the box off the CS exhaust hole, are there any other mods you would recommend? TIA.

Cadillac...thanks for the compliment. No, there is no residual odor from the varathane and in fact it was almost odorless during application. I didn't season the cold smoker before use because there is no heat inside the box...it doesn't exceed fifty degrees inside. I had originally planned to order the adjustable side rack holders from the factory but the guy that built this for me got creative and put in the furring strips that you see in the photo. So far I'm happy with it the way it is except for the moisture issue that I mentioned in my post but I'll get that solved by trial & error. I'm not sure that it is really an issue but I think that I would like a little "drier" atmosphere inside the chamber. As far as the inside dimensions of the cold smoker are concerned I wouldn't change a thing. I do plan on installing some cup hooks in the roof of the unit when I get up enough courage to try sausage and I also plan to support the door in the level position with stainlees steel wire instead of the wooden dowel that Im using now. It sure is a handy shelf. Good luck on your project!

I didn't actually do the cardboard box thing.. but I thought it would be a good, inexpensive way to do it. I would have just gone to the hardware store and bought some gas welding rods, cut them into pieces.. shove them thru the cardboard to hold small racks used to cool cookies or bread. They wouldn't have had to fit the box perfectly.. just had to be able to go inside and be able to support the weight of a few slabs of salmon or cheese..
Just an update on my "new cold smoker"... first of all I took Smokin's advice and raised the box 1/2" above the exit hole from the hot smoker and the internal moisture was almost eliminated! Thanks Russ!! I did a couple of pork loins this weekend that I cured for 10 days instead of my usual 2 days and they turned out to be the best that I have done. In fact, they are a lot closer to the "Canadian Bacon" that I have been trying to replicate for months but gave up on. I also did a beef tongue at the same time (I know some of you are gagging) but I used my pastrami cure on it and It turned out great. All in all..a great weekend.
