Roasting is determined by two parameters: hot air temperature and bean temperature. Hot air temperature is set on the left PID controller. It is a function of the bean weight. Bean temperature is set on the right PID controller. When this temperature is reached, the machine begins its cool down cycle.

Roasting is determined by two parameters: hot air temperature and bean temperature. Hot air temperature is set on the left PID controller. It is a function of the bean weight, and is the temperature of the air entering the roast chamber. Target bean temperature is set on the right PID controller, and corresponds to the temperature of the air exiting the chamber. When this temperature is reached, the machine begins its cool down cycle.

Hot air temperature range is 520-575 F on the controller. For 1-2 lbs, it should be set between 520-530 F. For 2-3.5 lbs, it should be set between 540-560.

Hot air temperature range is 530-575 F on the controller. For 1-2 lbs, it should be set close to 530 F. For 2-3.5 lbs, it should be set between 540-560.

Bean temperature can be set between 400-445 F.

Target bean temperature can be set between 375-445 F.
