After about a week the beans were dried and were put inside wagons that used a small rail system with a turning wheel in the middle to direct them up this bridge, using steel cables, and into the bunker silo.Coffee beans need to be dried before they can be processed and this was done here on top of these terraces. All the beans were distributed over them by a system of aqueducts helped by the fact that the terraces were built unevenly. The beans were washed in an installation situated on a higher level and came through underground aqueducts using only gravity to pop out from the holes we can see at the corner of the terrace.

Coffee beans had to be spread and revolved every two hours to get thoroughly dried; during this process, they could not get wet, so at night and when it rained they had to be gathered on piles on top of that bulge in the middle of the terrace called "moon" and then covered with heavy denim sheets.
