A Coffee Roasting Machine in a Roastery
A drum coffee roaster machine stands prominently on the wide floor of a small coffee roastery. A woven sack and a storage container sit near the roasting unit, while ventilation pipes and storage shelves line the surrounding room. The layout shows the key equipment used in processing raw coffee beans.
Facts About Roasting Coffee Beans
Drum roasters heat raw green coffee beans inside a rotating metal cylinder while hot air circulates through connected exhaust pipes. As the internal temperature reaches over four hundred degrees Fahrenheit, moisture evaporates and chemical reactions cause the beans to crack open, expanding in size and turning rich brown. The roasted beans are then dropped onto a cooling tray where perforated screens and suction fans stop the roasting process quickly.
