Hope this isn't a stupid question....but is there a fan you can buy FOR a conventional oven to help it act LIKE a convection?
Prior to the year 2000, maybe the 1990s, you could buy a fan (at Kmart) that sat on the top shelf of the oven. This patent describes such a device, a spring-powered wind-up fan. I haven't a clue if that patent, and the fan I'm remembering at Kmart, are related.
It isn't a stupid question, I am not aware of any such fan - one challange would be how to power it - batteries would not do very well in a hot oven. If you are try to get the effect of better distribution of heat, the only option I know of it to regularly open the door and turn the loaves, or even change the racks they are on. While the best convection ovens have a third element which is used to heat the air, many ovens labeled as convection have a fan at the back that just circulates the air heated by the baking element or burner - that can give better results than without such a fan - but it isn't guaranteed.
Just a couple of observations
What kind of pork ribs do you cook at 130ºF, ribs should reach an internal temperature closer to 190ºF kind of hard at 130º. Having given this some thought by setting the oven up the way you have the electric elements will stay on constantly so you are cooking the ribs through radiating heat not the air temperature of the oven.
You don't really have a convection oven you have developed a way of venting the heated air in your oven.
I too am looking to find one of those fans... Spring driven saucer shape fan.
I THIBK it is made by kitchenaire I have seen them a few times on ebay.
LOL I could kick my butt for not getting it when I saw it
they are cool they are spring driven kinda like a watch :)
P.S. IF YOU FIND MORE THAN ONE LOL!!!
I wasn't going to pay that ransom for shipping but here is the fan you are looking for!
Even if you are like me with the shipping thing, Here is what you are looking for!
