A device inside a grinder to peel the inner embryo membrane of coffee beans is disclosed. It has a motor with a motor shaft, a positioning cylinder located on the lateral side of a motor and having a lower exit inside a conveyor base, and a conveyor base, which is on the lateral side of the grinder and has an extruded exit end on the other side of the grinder. The motor shaft connects to an eccentric synchronic rotation grinding bar. During rotation, the grinding surface completely hits the inner ring rim of the positioning cylinder and coffee beans are ground into particles. When the particles fall, due to low specific weight, the embryo membrane is drawn by a fan located on the lateral wall of a grinder and is collected in a dust collection bag.
