Abstract:
A device to peel off inner embryo membranes on coffee beans, comprising: a grinder; a motor located on an internal wall of the grinder; a positioning cylinder mounted on a lateral side of the motor; a conveyor base, into which the positioning cylinder extends; a motor shaft extending from the motor and connected to an eccentric grinding bar for eccentric rotation of the grinding bar, the grinding bar fitting into the positioning cylinder and having grinding threads thereon such that grinding compression occurs between the grinding bar and an inner rim of the positioning cylinder; a top of the positioning cylinder connected to a funnel-shaped loading container, and a bottom of the positioning cylinder, having a grinding particle exit located inside the conveyor base; a lateral end of the conveyor base connected to a lateral wall of the grinder and an opposite lateral end of the grinder forming an exit end, the positioning conveyor being inclined such that ground coffee particles fall into the inclined positioning conveyor; and a fan on a lateral side of the grinder positioned so as to draw out inner embryo membranes after passing through the grinding particle exit.
