This is how I have the datalogging 2 probe thermometer set up in the front of the roaster. Then in the rear I have a non-logging single probe in the exit air flow of the drum. It's a setup that gives me exactly the information I need. My only last addition will be a flow-meter (in water column inches) for the gas so I can see exactly where the valve is set, instead of eyeballing the flame.
Travels of an L12: Moving the roaster from its old abode in San Francisco to Emeryville, just over the Bay Bridge, was an adventure. We had rented a truck but discovered the roaster was too tall. So we decided to move it in my pickup truck!
Roasting the first test batches! Actually, I bought several bags of mixed samples to roast up while working out a few probelms, and getting a feel for the burner settings (they are a bit different on each roaster).
