In agriculture, a '''pulper''' is a machine designed to remove pulp (i.e. the soft flesh) from [[agriculture|agricultural]] produce. For example, in [[coffee]] growing, the ripe red [[Coffee cherry|cherries]] are picked from the coffee bushes and, before [[fermentation (food)|fermentation]] and later drying, the soft pulp needs to be removed (otherwise a potentially uncontrollable fermentation/rot will occur).  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 (milling to remove the [[parchment]]) and then roasting.
