After harvesting, the coffee cherries are first sent to a settling channel, where the ripe and unripe cherries are separated from the floating "floaters." The beans are then placed in a metal cylinder. Here, centrifugal force separates the pulp from the coffee bean. After this process, only beans with a parchment skin and mucilage (a thin layer of fruit mucilage) remain. The coffee cherries are then dried in this state.
