Abstract
A green coffee bean polishing apparatus for removing silver skin from green coffee beans having the silver skins remaining after removal of parchment, comprises: a tubular member communicated at one end portion thereof with a supply port for green coffee beans to be polished and at the other end portion thereof with a discharge port for the polished green coffee beans, the tubular member defining a polishing chamber therein and having a large number of through holes formed in a wall surface thereof; a polishing roll rotatably disposed in the polishing chamber for serving to polish the green coffee beans in the polishing chamber so as to separate the silver skin from the outer surface of each green coffee bean; and an air passing means for passing air from the polishing chamber to the outside of the tubular member so as to discharge the silver skin separated from the green coffee beans through the through holes in the tubular member. Accordingly, the silver skin can be ensured to be removed from the individual green coffee beans.
