The Fresh Roast SR500 has the same capacity ( 4 scoops , 120 gm) and features of the SR300 —plus three temperature settings that can be adjusted any time during the roasting process.
High temp. = 490 degrees Medium temp. = 455 degrees Low temp. = 390 degrees
A Fan Speed Control has been added that allows the finest tuning of the roast.
The Fan Speed Control allows adjustments of + or – 10%. 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. As the beans become lighter, the fan speed can be turned down and keep the beans from chipping.
