A method for use of an apparatus comprises: a grinding step, a cleaning step, and a de-ionizing step; the apparatus comprises a receptacle to contain the product to be ground and provided with an unloading aperture; a fixed grinder; a mobile grinder rotatable around a rotation axis connectable to a drive motor; a cleaning device connected to the mobile grinder; a grinding chamber in which the fixed grinder, the mobile grinder and the cleaning device are located and provided with a discharge aperture to discharge the ground product.

A bean grinding apparatus including a body; grinding burrs mounted in the body, the burrs including a non-driven burr and a rotationally driven burr, the rotationally driven burr having a rotational axis about which it rotates; a drive motor operatively coupled to the rotationally driven burr; a grounds flow path defined within the body; and an exit spout, the exit spout having an inlet in communication with the grounds flow path and an outlet, wherein the exit spout defines a longitudinal axis and the longitudinal axis of the exit spout is angled with respect to the rotational axis of the driven burr.

A coffee bean grinder includes a machine body and a burr grinder. The burr grinder is detachably mounted to the machine body, and includes an adjusting mechanism, and a grinding mechanism. The grinding mechanism is connected to the adjusting mechanism, and includes an inner burr that is rotatable about a grinding axis, and an outer burr that surrounds the inner burr, and that is rotatable about the grinding axis relative to the inner burr. The inner burr is movable by the adjusting mechanism along the grinding axis relative to the outer burr so as to adjust a space between the inner and outer burrs.
