Coffee dispensing apparatus having a grinding mechanism

A beverage ingredient dispenser 24 comprising a hopper 66 for storing a beverage ingredient e.g. coffee beans; a grinder 76 for receiving the beverage ingredient from the hopper 66 via a first auger 84 comprising a first grinding element 78, and a second grinding element 80 located on a shaft 82 which is rotatable about an axis X-X to rotate the second grinding element 80 relative to the first grinding element 78, each grinding element comprising a respective grinding surface. The dispenser 24 also has an adjustable stop member (104, Fig.6) moveable along the axis X-X for limiting axial movement of the grinding surface of the second grinding element 80 away from the grinding surface of the first grinding element 78 during a grinding process. The adjustable stop member (104, Fig.6) may be a collar that extends around the axis X-X.
