The Fresh Roast SR540 is a good step forward on the most popular home coffee roaster. Easy to use, roasts a pinch more coffee and is more versatile with its heat and fan setting than the 500.
Roast capacity is 4 scoops, 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 air 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.
For your first roast, use about 4.5 ounces (4 scoops). The best batch size should be within about an ounce in either direction. Dependent on voltage, ambient temperature, and your roast preferences, you can play around with your batch size. However, the 4.5 ounces should basically work for everyone.
The New Control Panel:
The first slot on the LCD is fan Speed – settable from 1-9. 1=low 9=high.
The second slot on the LCD is heat – settable from 1-9. 1=low 9=high.
The third and fourth slot on the LCD is time – settable from 0.1 – 20 minutes. During cool mode it will display C.3, C.2, or C.1 as it moves through the cooling process.
The control panel has been significantly simplified. To change a field on the LCD: PRESS the turn knob, it will then flash the field you have selected on the LCD. TURN the knob to adjust the setting. All is real time. Beyond that, you have two buttons on the roaster; one for on/off and one for roast/cool.
- Put 4.5 ounces of green coffee into the roast chamber, set the roast chamber on the machine, set the chaff collector onto the roast chamber.
- Set fan speed to “9” and Power to “5”. Set the timer for 15 minutes. Total roast time should come in between 6 and 15 minutes dependent on settings.
- Hit the Run button.
- As soon as you start seeing good movement, move the Power to “9”. Usually 1-3 minutes into the roast.
- You should now be on “Fan: 9 / Power: 9”. This setting will get you close to 1st crack but from here you will have to start reducing fan speed to push the roaster up through 1st then 2nd When to turn down the fan is based on movement. Try turning it down 1 notch, if the beans stop moving turn it back up and wait approximately 1 minute before turning it back down.
- Assuming you have good movement, turn the fan down to “8” This should get you into 1st crack depending on variables such as ambient temperature, voltage, etc.
- Once the coffee moves a little better with fan “8” move to fan “7”
- If needed, repeat the last couple of steps down to fan “6”, then fan “5”.
- Hit cool button whenever you hit your desired roast, make sure to turn the fan speed back to “9”.
