Abstract
The present invention belongs to the field of mechanics and refers to a device for selective processing of mixtures of green and ripe coffee cherries. Said device is a helical conic apron comprising vibro-elastic inserts which pliability allow them displace proportionally to the size and hardness of different coffee cherries. Additionally, the present invention refers to an integral machine comprising helical conic aprons with vibro-elastic inserts, which does not use water and is designed to receive mixtures of ripe and green coffee cherries, depulp ripe cherries, separate semi-pulped green cherries by a separating machine and remove the pulp from ripe cherries. Finally, the present invention refers to a method for the selective processing of mixtures of green and ripe coffee cherries by the use of the already mentioned integral machine.
