vPulping involves the removal of the outer red skin (EXOCARP) and the white fleshy pulp (MESOCARP) and the separation of the pulp and the beans. Immature cherries are hard to pulp. Therefore, if the coffee is to be wet processed, correct harvesting is essential.
Two main common Pulpers.
Involves a rotating drum with a punched sheet surface and adjustable breast plate between which coffee cherries are pulped and the breast plate has to be adjusted so that the pulp is removed without damaging the beans.
These can be manually operated or attached to a treadle or bicycle. For larger scale units, motorized drum pulpers are available.
Entails the use of a DISC with roughened surface.
