Coffee Roasting Process

The essential coffee roasting process involves steps that are followed carefully. The first step involves sorting the green beans. In small households that roast coffee, it usually involves screening the green beans by hand to remove the debris.

Factory Sorting

In larger operations where large volumes of coffee beans are being processed for roasting, bags and bags of green beans are opened and dumped into a hopper where the beans are screened to remove unwanted debris. After the screening process, the coffee beans are then weighed and transferred to the storage hoppers via a conveyor belt.

Sorting to Roasting

From the storage hoppers, the green beans are then brought into the roasters where temperatures can range from 188 to 282 degrees Celsius. At this temperature, the coffee beans are then roasted for a certain period of time ranging from 3 to 30 minutes. Typical coffee roasters look like horizontal metal drums that are headed from below and rotated continuously as the beans are being roasted. This allows the green beans to tumble about in a current of hot gases.

There is also another type of coffee roasting technique where the green coffee beans are inside the drum roaster where they are being roasted under a cushion of heated air. This type of roasting process is called a fluidized bed and was first introduced and developed by Michael Sivetz and was patented on June 22, 1976.

Roasting Profile

Coffee roasting usually involves following a certain recipe which includes the length of time the coffee beans are left in the roaster. This is called the roast profile and it aims to bring out a characteristic flavor and aroma from certain types of coffee beans. Different roast profiles are used in order to bring out or highlight a certain characteristic of coffee according to its desired flavor, aroma and taste. There are various factors in which a coffee’s roasting profile may be determined. There are factors such as the origin, variety and desired flavor of coffee that come into play when deciding on the right roasting profile.
