Charcoal MOD for the Mighty Pizza Oven
« on: September 21, 2013, 07:27:30 PM »
I built a charcoal adaptor made of wire mesh. This adaptor can be inserted in most charcoal grills or you can simply place it on the ground perfect for making pizza while camping or any anywhere you can imagine. I used 1 1/2" charcoal chimney which kept MPO temp high to low 600 for over an hour.

What do you think of this setup? do you love it or hate it?

Why not a spiral rather than concentric circles?

Do mean spiral all across? I wanted most of the heat to reach the back of the top stone.


Another use of the   adaptor, is to grill meat at different temperature.

I was thinking of something more like this for better airflow maybe?

Nice job, it looks real. I like the idea, not sure if the draft is strong enough to reach the end.

I left the 2" open at the bottom all around to creat chimney effect. the concept worked. But It can be much more efficient based on another experiment I did (can't share in this post) where I was able reach extreemly high temp. The brickets were glowing red hot just by natural air draft.

One thing I think I see.  You have air gaps around the stone that are allowing unheated air to enter the oven chamber.  I would personally try blocking these off with some foil and routing all the air into the oven chamber through the coal pile at the back that runs the entire width of the oven.  With the updraft design and damper you should be able to control the airflow and regulate the temperature pretty well this way.

Definetly there are room for improvement. My objective with this test / simple setup to find out if it is possible reach descent baking temperature even with this crude setup.

MPO users have the option to use charcoal or gas.

Is all of the charcoal suspend by the wire mesh above the foil on the ground?

It is not suspended.

I am planning to do another test where it will be suspended about 2" of the ground and all sdes are blocked except for 1" off the ground form the back side.

Im just thinking about all that valuable heat getting sucked up by the concrete.  I dont have an answer either. lol.

Gene, this was just a rough test, simple and easy to build. I will be building an improved version to see how much heat  improvemt I can get.

A different design... high 900's top stone, it start to go down once i insert bottom stone which eventually reach higher temp than top stone....

Using the setup shown in my yesterday test, except, i increased the size of the inner circle and used one layer of charcoa (85 briquettes) . MPO temperarture was between 700 and 650 during baking.

Emergency dough 50% Caputo, 50% KAAP, 60 % water, 30% starter, 3% salt

Next week, I will try 2 layers of charcoal. It should get MPO temp in high 800's.

Today bake time was about 3 minutes.

Bert,
loose the briquettes.  Briquettes are made with clay for a binder.  As anyone that has used briquettes knows, there is a lot of "ash" from them.  This is really a small amount of real ash and a lot of clay residue that doesn't burn.  The clay moderates the heat.

Get some real wood (a.k.a. "lump") charcoal.  In particular, get some mesquite wood charcoal.  It burns among the hottest of all the wood charcoals.  You'll be amazed.

bbqchuck, I don't like the amount on ash from briquettes, but I like that I can determine MPO temperature based on the amount of briquettes used.

I experimented with lumps before, I am still not experienced enough to get consistent results with lumps. Mainly due to lump  irregular size. It does generate far less ash and more heat. I bought a big bag of lumps from Sams club, some piece were huge which make it difficult to distribute evenly even after I broke them into smaller pieces.

My last configuration worked the best, It provided even heat MPO bottom stone. MPO can be used on any charcoal grill, just by building a square using metal flashing to direct the heat under mpo and to place charcoal in a desired configuration.

I could also raise MPO temperature using the same configuration and same amount of briquettes by raising the charcoal height. In my yesterday bake, the distance between charcoal grates and cooking grate  was 4".

Bert,
A little late, but that pie looks tasty.  I guess it's all gone now  :-D

Hey, just a word of caution.  Be careful about using that rabbit mesh if it's zinc plated.  Zinc in large amounts is toxic.

Not sure about zinc poising, I bought the wire mesh from lowes. I was not able to find if it contain zinc or not. Even if it does, it is not comming in contact with food, it is only used to contain the charcoal.

Looks galvanized, which means it is coated in zinc.  It doesn't need to come in contact to be an issue, the zinc burns off and the fumes are an issue.
