Insulated dual cabinet smoker
SmokingMeatForums.com Top Picks
A commercial smoker using a design I have been kicking around for a while. I should have it done in a week or so if other work permits. Will have 10 racks of 850x950mm with 190mm clearance between each rack. Has a center firebox with 2 lower warming drawers on the outside. Heat goes up the internal chimneys then down through the racks where it enters in the lower part of a false wall the up the outside walls to vent. Sheetmetal is 2mm (#14).
Can't wait to eat some BBQ out of it.
It doesn't have an owner yet, so will have to be the shop pit until it sells.
Back of firebox. There was a bunch of welding to do, so I got the young guy in the shop to do it as he wants the practice. I probably will put in a sacrificial plate in the top of the firebox for better dispersion of heat and longevity.
Nearly done, I will weld the doors on tomorrow. I added another 1/4" plate to the inside upper part of the firebox to help disperse the heat. tomorrow I hopefully will throw some wood at it and see what it does.
You will have to wait until next week to see smoke as it is vacations here Friday and Monday. I also have a bunch of running around to do tomorrow sourcing parts for other smokers.
The outside wall where the 4x2" is on the flat edge has a false wall on the inside.
On the right side of this pic you see I placed the vertical 4x2 on it's flat edge to give me a 2" gap for the false wall then 2" for the insulation. The smoke enters at the bottom of the angled plate.
Doors welded on.
Sorry about the crappy photos as it is the shortest day of the year here. Sun is always low in the sky all day. Tomorrow I will fire it up and see what happens.
I was going to do some testing today but my laser thermometer took a dump. First redings where a 30f split top to bottom, but was barely up to temp. It wanted to run hot all day at 250-275. I did take it up to 400F to burn off the crap a bit. Strange thing was it always favored the right hand exhuast even though there was not wind and was level.
Let me know if you need the CAD designs for the chassis. After todays test run I would also make a few little tweaks.
The BBQ was good today, but not up to competition standards. I was too busy working on making a gantry as I have 6 250 gallon propane tanks coming soon.
I also need the gantry so I can move that 1000kg ripper off a bulldozer and flip it over to make a table. The other part is in the background and am going to make a hydraulic press out of it.
Maybe this weekend i will have time to do some Beef ribs without too much interuption..
