ABSTRACT:
A coffee grinder comprises a bin for holding a supply of coffee beans to be ground, a grinding assembly for receiving beans from the bin and grinding the same to a desired grind size, and a collection receptacle for receiving the ground coffee from the grinding assembly. The grinding assembly comprises blades for cutting the beans to a relatively uniform size, which blades are configured and located for feeding the cut beans in an auger-like fashion to burrs. The burrs are configured and arranged for grinding the beans to a desired grind size and for delivering the same to the collection receptacle, such that the beans make a single pass through a grinding path comprising the blades and the burrs.
