Q: I recently purchased a Klose pit (first time purchase – figured might as well get something I'd be happy with for a long time).  Anyway, I have characterized the temperature profile with the cooking chamber and the data shows temperature gradients that can exceed 70 degrees F.

My question is if you know of techniques that can be used (e.g. internal fans, etc,) to mitigate such a huge temperature gradient.  Trying to keep something at a fairly tight range means you can't utilize a large portion of the smoker.  I've thought about building a deck that will fit above the heat intake area from the fire box that would fit below the grating that would disperse the heat in a more even fashion.  Anyway, your thoughts would be appreciated.


A: That is a very common phenomenon in offset smokers.. where the heat comes from the firebox into the smoking chamber there should be a sort of baffle to help disperse the heat and hot exhaust gases more evenly. With no modification it tends to be hotter at entry and gets cooler as you get further away from the firebox toward the stack end.

The best modification is to install a metal baffle just like you mentioned and should extend to nearly the full length of theh smoker. I have seen some which have vent like cutouts all along the length of the baffle, smaller cutouts closer to the firebox and getting larger as you go along toward the opposite end.

You can also fabricate a rack to hold a pan of water right where the firebox opening is, blocking the heat, and instead heating the water which creates 212 degree steam which will also help regulate the temperature in the smoke chamber.

You do not have to spend a lot of money or even weld this baffle in place.. a lot of these baffles are fabricated from simple metal flashing and bent into shape by hand and installed with just a few bolts.

Here is a link I found which may give you some other ideas as well:

    Jeff et al.,

    A quick fix to the temperature distribution issue is to place an opened can of Eighth Wonder Hopston IPA at the end of the bottom tray at the firebox entry to the cooking chamber. Just sayin'.
