DreamRoast, Driving with Bean Temp. RoR
The Dreamroast now has a bean temp. RoR(rate of rise) meter. The datalogger in the back left displays the ET (environmental temp.)in the roasting pot. And the BT (bean temp.). The DMM displays the rate of rise of the bean temp/min. A Homeroaster made the circuit board to connect between the thermocouple and the DMM.
The live numerical RoR works really well with manual control roasting.
