ABSTRACT:
A coffee beam weigher and grinder comprises at least two storage hoppers each respectively receiving and storing a supply of coffee beans, the hoppers each defining a bottom outlet opening through which coffee beans are gravitationally flowably releasable. Sliding hopper valve plates control release of coffee beans from a selected one of the storage hoppers, and coffee beans are released into a bean bucket deployed below the hoppers. The bean bucket is mounted on a bucket arm pivotal between upper and lower positions and is releasably held in the upper position by magnetic attraction between first and second magnetic elements. The bean bucket has a bottom discharge opening which is blocked by a depending stem valve when the bucket arm is in its upward position. The second magnetic element is one of a plurality each of which provides for release when a selected amount of coffee beans are received in the bean bucket. Upon release of the magnetic elements, the bean bucket pivots downwardly and bean flow into a coffee grinder. The discharge from the coffee grinder is caught in a brew basket or a ground coffee receptacle bagger having a valved bottom discharge spout for filling coffee bags. A rotatable control knob selectively operatively positions one of the second magnetic elements and also selects the hopper and a grind time for the grinder.
