Hi! Looking for a legacy inlet temp sensor on 13 yr old Gene Cafe. It seems they've changed it and now you need new mother board and new sensor. Any ideas where I can find compatibile old one? Mark

peveleth, It is better if you start a post in the forum with your question. These shouts go away in time.

The Beef Tips
BeefTips
Hello Everyone, my name is DJ. I'm from Florida, USA. Im about as new to roasting as can be since I habe yet to start roasting. I have a popper and a bread maker. I bought the popper and decided I really wanted something different. I'm going to make the classic bread maker/ heat gun set up soon. I found this website by simply googling home made coffee roasters one day. I have lurked as a guest for a while and decided it was time to get access so I can ask questions and comment on threads. Looking forward to learning about roasting from Y'all!

Welcome !

I would consider the flour sifter or rolling drum/cage approach instead bread maker, much even heat distribution and better agitation.

Big welcome to Homeroasters! We're looking forward to seeing your roaster come together whether it be breadmaker or any other method. BTW, I've had some way over the top killer cups from HRO members roasting in the classic "Corretto".

Post often and have fun!!!

Renatoa I havnt considered the sifter. My concern with it is how can I make the the agitation manual? With the roller drum that was my first thought. I was going to use a counter top rotisserie oven. That doesn't give the necessary heat or agitation. So I've settled on the bread maker and I already have started getting everything for it.

There are 20-60 RPM motors everywhere, I don't see the issue... even a $10 screwdriver can be used for this purpose.

I spent a lot of time to study proper agitation in a stir crazy style pan, and having now a better understanding of the beans circulation I don't find a bread machine satisfactory for this task.
Too many layers of beans, thus too big temperature gradient from bottom to surface, a paddle that not guarantee a good vertical circulation, heat source too focused, all of these are factors discouraging the use of such machine, no matter how many success stories are reported here and elsewhere.

Good luck !

When optimum batch size is not exceeded, the agitation capabilities of a breadmaker often cycles beans back to heat source faster than a typical fluidbed roaster. Stir Crazy and breadmaker are two different animals. Jump to 1:12 in the video

Allenb what is your recommendation for batch size. I'm sure every machine is different but just am average size for the correto machines.
 
renatoa
Allen is right when you see this kind of movement in the bowl.

The pessimistic thoughts I wrote above are inspired from my fellows experience filling the recipient until the agitator is buried under beans and no more doing its job.
Probably you should stop adding beans when you still see the shaft.

From what I've seen, depending on bowl dimensions, 1 lb seems to allow very good agitation but maybe more is possible.

Thanks for clarifying the issue at hand. Yes, as with all cooking appliances, overloading is bad and will produce inferior results. I used to try and squeeze in a couple more ounces of green into my drum roaster than I should and produced poor results in the cup.
