I am a long time reader, and avid pizza maker. I started out with a simple self cleaning oven hack, moved to an LBE, and now a full blown wood fired oven. I love making pizza, but I am also a technology control geek at heart. As an engineer, I always am excited for pursuing perfection through computer based control. (I put a PID controller on everything that will take one, my espresso machine, smoker, sous vide, the works).
I know that pizza is an art, and many will take offense to the fact I am trying to build a highly controlled oven, but for those people, i simply ask, please look away.
So, here is what I am trying to do.
I have been working on a design of a wood burning oven with a supplement of either gas or electric with a highly controllable temperature system. The idea is to have the floor of the oven PID controlled so I can set it to 800 (or any other temperature). In addition, I am looking to control the oven air temperature with variable control. For example, I would like to start the pizza "cycle" with a 800 floor/ 1400 air temp. This will last about 10-15 seconds, then i will go 800/1200 degrees for the last 75 seconds (these numbers are just pulled out of the air, if anyone has specific numbers, please share).
In order to make the fire run at such high heat, we have been looking at running a forced air system connected to a centrifugal blower
, run by an arduino controller. This forced air system should be able to make the wood fire burn within a much higher range of temperatures. I know that traditionalists are against this, but we are looking at implementing a gas powered or electric coil system (similar to a ceramic kiln
) underneath the floor of the cooking base. This cooking floor heating element will be independently controlled by another arduino/pid.
We are looking to make all heating elements reside OUTSIDE of the main cooking chamber. The chamber should be pure heat. We have thought about keeping all the heating elements below the oven. The wood/air burners will be offset from center, and the gas or electric heaters in the center.
I have a friend of mine currently working up a 3d model of our rough plan design, so I will post this shortly.
That being said, I am looking at several designs, and have the resources to make this happen....but, before I begin, I wanted the insight of the pizzamaking.com community.
All insight is very much appreciated.
