ProcesseditThe coffee roasting process follows coffee processing and precedes coffee brewing. It consists essentially of sorting, roasting, cooling, and packaging but can also include grinding in larger scale roasting houses. In larger operations, bags of green coffee beans are hand or machine opened, dumped into a hopper, and screened to remove debris. The green beans are then weighed and transferred by belt or pneumatic conveyor to storage hoppers. From the storage hoppers, the green beans are conveyed to the roaster. Initially, the process is endothermic absorbing heat, but at around 1. C 3. 47 F it becomes exothermic giving off heat. For the roaster, this means that the beans are heating themselves and an adjustment of the roasters heat source might be required. At the end of the roasting cycle, the roasted beans are dumped from the roasting chamber and air cooled with a draft inducer. During the roasting process, coffee beans tend to go through a weight loss of about 2. Although the beans experience a weight loss, the size of the beans are doubled after the roasting process due to the release of carbon dioxide, release of volatile compounds, and water vaporization. In Vietnam coffee is often coated with oil traditionally clarified butter and a small amount of sugar prior to roasting to produce a butter roast. The roasting process results in an additional caramelized coating on the beans. Equipmentedit. Diedrich infrared drum machine One of the most common roasters used to roast coffee beans.
