Pulper

In agriculture, a pulper is a machine designed to remove pulp from agricultural produce. For example, in coffee growing, the ripe red cherries are picked from the coffee bushes and, before fermentation and later drying, the soft pulp needs to be removed. In the case of coffee, the pulping is normally done in a pulper that is either hand-cranked or engine-driven; the beans come into contact with a rotating spiked drum that removes the pulp or flesh. The sticky beans that result from this process then have to be washed, fermented, washed again and dried, before further processing and then roasting.
