What is the process of depulping a coffee bean?

Depulping is the process of separating the coffee seeds from the outer layer of flesh.
Many producers have hand depulpers on their farms or share a hand depulper with their neighbors. A hand depulper is a machine with a small rotating burr that tears off the outer layer of the coffee flesh, exposing the two coffee seeds inside. Some producers operate their depulpers by hand and others have mechanized them to help with the labor. The depulper deposits the coffee seeds into a tank and the remaining skin and flesh is separated and commonly used for compost.
