Fresh Roast SR-540 Coffee Roaster
The SR540 is the newest addition to the SR family of coffee roasters. Roast capacity is 4 scoops or approximately 120 grams. It has an improved control board. All adjustments are made with pushing the knob and turning to adjust the heat, fan, and time. It also features a real-time temperature read out. A quick turn of the knob to the right will display current temperature. There are now 9 levels of heat adjustment compared to having a Low, Medium, and High adjustment. The fan also has a wider range of adjustment. The chaff basket and top lid from earlier SR roasters will not fit on the new SR540. The roasting chamber is a much larger diameter. Users are also able to change the default start settings.

The default settings are meant to be changed.
Using the button, press down to get the first value on the display to blink. These will be the fan settings. Change the fan settings to 9, then depress the knob to change the heat setting to 4, and depress the knob again to change the time setting to 10 min. Press the Run/Cool button and your roast will start. The graph below will display the settings used throughout a roast. There are many variables that come to roasting and if your time is off by 2-4 min, that is okay. As long as the beans are being roasted in under 18 minutes and you are seeing temperatures above 430*F. To see the temperatures, first, check that there are no digits blinking and then turn the knob clockwise quickly. This will display the roaster temperature.
