The most important step in processing coffee beans is roasting. Roasting of coffee beans takes place in the temperature range of 370 to 450 degrees for about twenty minutes. This makes them lighter by 18 to 23 %. Their color changes from light green to medium/dark brown. Further, the beans split open and emit the rich smell of coffee. Coffee roasting is an art and science that requires experience and the right kind equipment. This is where coffee roasters enter the scene.

Features of Modern Home Coffee Roasters

While ovens have long been used for roasting coffee beans, now modern home coffee roasters make it possible to carry out the roasting process at home without any effort at all. With these devices, you can easily roast up to half a pound of green coffee beans at a time. With their one-touch operation, all you have to do is put green coffee beans into the roaster’s roasting drum. Close the lid and set the roasting level as desired. Your work finishes here. The roaster will automatically complete the rest of the process. After the beans are roasted to the desired level, it will cool the beans, give out the chaff (fine skin that detaches from the beans), and pour the beans into the bean cup. These are ready for use now.

The modern home coffee roasters can be adjusted to a range of roasting levels, at least fifteen different settings, to the users. The resulting coffee beans vary in appearance from a light cinnamon, to medium, or to a dark French roast. The rosters carry an adjustable ventilation system allowing it to vent externally or to a stove/ range hood exhaust.

Modern home coffee roasters are easy to clean. Made of stainless steel, their drum, roasting bean cup, and chaff tray are safe to wash with dishwater.

Care in Using Coffee Roasters at Home

One important point of care in using a coffee roaster at home is to place it in a well-ventilated area or next to some external vent such as a counter top vent or a stove/range hood exhaust. This is because the roasting machine emits smoke while roasting the coffee beans. Never leave the room while roasting the coffee, even if the roaster is automatic. Also, do not clean your roaster too often. Finally, roasting on a porch or near a partially open window is fine but cold temperatures will badly affect the roast.
