Building a Gravity Fed Smoker

Post by beaver » Thu Feb 05, 2015 11:17 pm

A mate and i sat down in a Cad program and drew up the cabinet smoker design and firebox and so far its looking pretty smick.

This thread will be reserved for the build/design photo's.

i will release "snippets" of the build but the current design criteria are

- must be transportable and not exceed 300kg dry weight (so far this seems easy)
- must be able to cook 2x briskets, 2x pork shoulders, 5 racks of ribs, 20 chicken thigh's, 2x lamb shoulders all at once.
- must fit Gastronorm pan 1/1 530 ×325 mm with sufficient airspace around for standard flow
- must be able to be maintained both using a blower and standard draw
- must be able to manage smoke input
- must last 3+ years
- must be able to be transported on soft ground (gravel/grass)

smoker is coming along nicely, will be ordering the insulation/hardware probably by the end of next week.
due to being built in australia the design was deliberately more material heavy than labour heavy

n00b question
How do you stop the supply from catching fire?

the "Chute" does not have a flow of oxygen (going up) due to a sealed lid at the top.
Fire will follow air/oxygen flow which will naturally progress in the ash catcher opening, up through the grates and then into the cooking chamber (as there is a chimney at the top)

Much like with a pellet cooker where the fire does not go up the auger due to o2 void

there will be an amount of radiant heat but that will not reach far into the chute

That's coming along nicely! It's gonna be heavy!

There are Plenty of these "Stumps" clone designs around, they work well!
Do a search for Stumps Smoker Clone.

Yup, like a clone but not using any box steel :)
At the end of the day it will be labled a stumps clone but they are essentially a rocket stove

All my own dimensions as well

Yeah, I can see, no frame! That'll cut the weight! You'll still need a good trailer and ramps to get it to a comp! :D

A Rocket stove is a completely different thing however, they work without a fan and without gravity feed and the need for making the hopper airtight.

There are gravity fed rocket stoves, it uses the same principal. Also the stumps and other gravity feds don't use/need a fan.
There is a pellet be smoking Jim bought that uses gravity fed pellets instead of auger driven that has many of the same design principals

I would think this will be the most challenging and will watch with interest as you test!

Wangs Website: http://www.allchinas.com/ I've got the one with the round barrel you see on the top right, in fact I think that is a pic of the one he made for me. And I have a stand alone gravity burner that I'm putting into a box being built as we speak.

Cheers
