Abstract
A device for storing and dispensing coffee beans, comprising a hopper defining a chamber adapted to contain the beans and provided, on the bottom, with an admission opening; a support base to support the hopper; a rotary dosing device rotatably mounted in a seat to rotate from and to a rest position, and provided with at least one cavity open on the outer surface of the rotary dosing device; and vacuum generating means to create and maintain the vacuum within the chamber. The dosing device has at least one annular groove engaged by a V-ring seal comprising a sealing lip, which, in said rest position, is compressed against an annular surface of the seat to seal the chamber and it is oriented relative to said seat, so as to be further compressed against said annular surface when subjected to a vacuum created in the chamber when air is sucked out therefrom.
