Abstract
A coffee grinder suitable for home use can include a housing that receives coffee beans, a grinding component within the housing, a removable container that receives coffee grounds dispensed from the grinding component, and a base located beneath the grinding component that supports the container. Magnetic components in the base and removable container can optimally align the container when placed atop the base. A knocker system can dislodge ground coffee residue into the container when actuated. An intelligent drive system can utilize feedback to drive the grinding component at a constant speed to minimize coffee grounds size variances. A grinds chamber in the housing can define an asymmetrical cross-sectional geometry. An auger that drives the grinding component can have an outer thread that forces coffee beans through the grinds chamber, and a grinds chamber housing can include a protective shoulder that covers a lead-in portion of the outer thread.
