The ROR is the number of degrees per minute that the bean-pile temperature is growing at any level throughout a roast. An ROR curve is a graphical plot of that knowledge throughout a roast batch. The ROR tends to decline throughout a roast, primarily as a result of the temperature gradient (differential) between the beans and the roasting setting decreases. Please note that the actual” ROR doesn’t go up early in a roast as the curve proven here implies. The actual ROR initially of a roast is quite high and drops precipitously through the first minute; however, as a result of the bean probe that recorded the curve was hot at the cost, and the probe took a few minutes to shed its heat and match the temperature of the beans, the curve incorrectly implies that the ROR began at a low destructive quantity and elevated for the first 2:30 of the roast.
