And a very busy control panel. Enjoy. Thanks to don clayton of clayton coffee and tea. If you are in the central valley of california, they are topnotch.

Thanks for taking and posting the pics. Very nice.

So the big boy is a 3 stage burner. From what I've seen over the years, the larger Probat roasters (bigger than an L-12) are typically set up that way with or without profiling capability.

If you get a chance I'd love to hear how they make changes to the heat input using the gas valve. Seems like it would be a very crude, non-repeatable control method. OTOH, that's all I've typically seen for control on the L-12 and smaller.

A sacrifice had to be made in the acquisition of the foregoing probat photos. Something had to die. Allen, you wanted internal shots. I got a couple. Scott, you had mentioned something about a total roaster meltdown. I got a couple roaster related meltdown photos. The lower roasted chamber.

i finally got more beans and a couple more pics. Three tube burners, flat on top. Holes the entire length. Controlled by this knob.
