Instead, the pericarp is removed by a machine, the berries are spread on the ground, dried and then moistened, and the dried flesh is ground with a special machine to remove the seeds. Mantenin in Indonesia is mostly semi-washed. Brazil has also used semi-washing in recent years, which is the only country in the world that has both sun, water and semi-washing treatments.

Beans dried in the sun are often made of foreign bodies or stones. The flavor of the beans treated by this method is complex, with the taste of the sun, the fruit flavor is very strong, and the consistency is better than that of washing, but the appearance of beans is not good. General Brazilian beans as well as Manning and mocha are typical sun-treated beans.
