With the Fresh Roast SR540, you can roast around 4 ounces (120 grams) of green coffee. This roaster has an improved control board from previous models. 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 the current temperature. There are also now 9 levels of heat adjustment, instead of just low/medium/high. The fan also has more adjustment options.
The roasting chamber is larger in diameter, so the chaff top, basket and chamber from previous SR models will not work with this roaster.

When starting the roast, the beans are at their heaviest. The fan speed can be turned up to keep the beans fluid and give an even roast. Then, as the beans become lighter, the fan speed can be turned down. The slower the fan, the hotter the roast. But be aware that a lower fan speed will also not lift the beans as well. So you may want to play with bean volume a bit as well. The combinations can be endless. you'll find that a faster roast will give you a lot more snappiness in the cup. You'll also find first and second crack (see Roasting 101) fall closer together, so listen for that.
Faster Roast = brighter cup. A slower roast will help to draw out body. If all goes well you'll have to adjust your roaster to exactly the way you like it. The SR series home roasters roast around 4.2 ounces at a time. This can depend somewhat on the power supply and the beans themselves. In practice, you'll find that you can get away with roasting a bit more or a bit less depending on your own conditions. An extension cord, for instance, is not recommended because it can reduce the power supply. Roasting outside where the machine will have to heat up cold air is also discouraged. Let common sense be your guide.
Roasting coffee can produce some smoke. Managing this depends on the amount you're roasting and how dark. If you have a stove top vent that's usually enough. But if you like especially dark roasts you might choose to roast less coffee at once. You won't see a lot of smoke until you get to a darker roast.
We can't say enough about the Fresh Roast line of roasters. They are some of our favorites. The glass chamber allows full visibility of the beans. Smoke control is easy to deal with. Both of those points are a big advantage on their own. But the price is excellent as well for all that they do. The Fresh Roast roasters are a reliable and cost-effective; way to roast coffee at home.
Please note: The standard warranty on glass chambers is 6 months. We recommend waiting 30 minutes between roasts to help reduce the risk of damage to the chamber.
