Abstract: A conical burr coffee grinder can include a hopper that receives coffee beans, a grinding arrangement beneath the hopper, and a removable container beneath the grinding arrangement. The grinding arrangement can include an inner conical burr within an outer conical burr. At least one conical burr can rotate with respect to the other to grind the coffee beans into coffee grounds and dispense the coffee grounds into the container. The coffee beans and coffee grounds can follow a substantially vertical path from the hopper through the grinding arrangement and into the container, which can be multipurpose. A rotor gear can be coupled to the inner conical burr such that the rotor gear and inner conical burr rotate together as a combined unit. Additional components can include a rotational motor, a geartrain, a removable hopper lid, a grind adjustment assembly, a chute, an ionizer, a base, and a safety switch.
