Thermocouplers and rotiserrie help
 
Hello all,

My wife is visiting the US next month so its my chance to get her to pick up some stuff from the US as our exchange rate is fairly good at the moment.

Is there anyone that can recommend thermocoupler manufacturers for the pizza oven so I can measure temps in atleast the dome and hearth also any recommendations on Digital or analog temp gauges would be great.

Now my 2nd question is a little wierd I guess and not to sure if I really will need to do this as the whole concept of the dome is even cooking through out the dome. I have mentioned on a few posts that I will be doing tandoori chicken, tandoori lamb, roasting turkeys fo thanks giving and xmas for my wife when she is here :). I was thinking of putting at the back of the pizza oven a stack of bricks with the 2nd or third course maybe having 3 holes drilled into it and when I am doing tandoori chicken or a roast putting them on skewers and having a brick setup that can be removed when not used at the fron of the oven that will raise the meat off the floor and cook while suspended. Now my question is does anyone know of any bearings that can maybe be added to the back of the oven inserted into the bricks so I can add a motor to the outside to maybe rotate the meat to cook evenly.

Any ideas would be greatly appreciated.

A plain bronze bearing (not oil inpregnated), like this:

MSC Item Detail

should do the trick. Bronze melts at 1743 degrees farenheit, so should be easily able to withstand our thousand degree fires. Also, they're cheap if they do need to be replaced.

There are also pillow block mounted bronze bearings, but the only ones I could find quickly had aluminum blocks, and that wouldn't work. These will tilt to compensate for slightly different shaft angles, but I doubt you're using thousandth of an inch clearances here anyway.

Dmun,

Thanks for that info will look into them right now. Do you have any info on the thermocouples as to what are good brands and how many should I do I know some people have done like 8 but that seems a little extreme to me, would I need more then a hearth one and a dome one?

Thanks again

Check out Auber Instruments for thermocouples with wires that will take the heat. I found a dual digital temp gauge direct from china for 20 US that has done the job quite nicely.

Hi ikhan42

check out the following, specialists in thermocouples and a branch in most capital cities:

Mechtric

I got my gear from them.

Also do a Google search in Australia or "thermocouples australi"!

PS Rastys had a green coffee bean roaster come rotiserie with adjustable height and slides into the oven which would make life much easier than trying to line up a long heavy loaded and can be put through a hole in the oven door which would help to hold in the heat.

Thanks for that info guys.

Nissanneil,

I like that rotisserie any idea why the cage though instead of using the sharp clamps that go into the meat that is being cooked?

I will see if I can get a metal welderer to do something similar for me. The reason I was thinking about the brick one was that once the skewer are out dont have to try and move a hot metal frame out of the oven for making things like Naan bread, or yorkshire puddings :).

Also just an after thought is the motor reall needed or is it enough to just suspen the heat in the oven as my understanding of these ovens is that the heat radiates in a circular motion so wouldnt that cook whatever meat is in the oven evenly?

Thanks again guys.

I believe this 'cage' was made to roast coffee beans in his oven, not to put meat in an then rotate!
It was built to be removed and 2 or more spiked meat holders slid onto the shaft yo hold the chicken(s), turkey, side of lamb, pork etc.
Send him a personal email to check on his progress.

I found a dual temp meter similar to mine that works quite well.
DM6801A Thermometer K Type Digital Temperature Meter - eBay (item 220512689783 end time Dec-18-09 08:05:35 PST)
