煎機。an electric heating device that heats a roasting chamber; a temperature detection circuit that detects the indoor temperature of the roasting chamber and/or the temperature of coffee beans in the roasting chamber according to the resistance value of a temperature-sensitive variable resistance element; The control circuit includes a control circuit that controls the electric power of the electric heating device based on the output of the detection circuit, and the control circuit controls the temperature when the output of the temperature detection circuit corresponds to a lower temperature than the heat retention level.
a heat retention control function that turns off the electric heating device and turns it on when it corresponds to a low temperature; and a counter function that counts the on time each time the electric heating device is turned on when the electric heating device is at body temperature due to the heat retention control function. , when the output of the temperature detection circuit corresponds to a temperature lower than the heat retention level even when a predetermined time width has elapsed from the on-time counted by the counter function, the temperature is shifted from the heat retention state to the roasting state. An automatic coffee bean roasting machine characterized by having a roasting command function that causes the electric heating device to be continuously turned on so that the electric heating device is turned on.
