A method of operating a grinder includes acts of: starting a first grinding cycle of a given duration; feeding the grinder with a given amount of material to be ground and grinding the material by rotating a rotary grinding member of the grinder for a period of active grinding; idly rotating the rotary grinding member for a period of idle rotation following the period of active grinding, for removing residual ground material from the grinder; estimating when the given amount of material has been ground, based on an operating parameter of the grinder; and adapting the given duration for a subsequent grinding cycle based on an estimated duration of the period of active grinding of the first grinding cycle.

An apparatus for extracting a compound from a substance comprising an extraction chamber arranged to extract a compound from a substance stored within the extraction chamber, wherein the extraction chamber is arranged to agitate the substance; and when upon the substance is under an applied heat, the extraction chamber is arranged to extract the compound into an air flow passing through the extraction chamber.

A coffee grinder, in particular for the installation in a fully-automatic coffee machine, including an electric drive motor (1) for driving a grinding unit, wherein a reduction gear (4) formed as a planetary gear is arranged between drive motor (1) and grinding unit, with the sun gear (3) of this planetary gear being drivable by the drive motor (1). The planetary gear includes multiple planetary rods (8) arranged in the circumferential direction around the sun gear (3), these rods including a first axial portion (7) meshing with the sun gear (3) as well as an axially neighboring, second axial portion (9) with a second diameter different from, preferably smaller than, a first diameter of the first axial portion (7), with this second axial portion meshing with a stationary ring gear (11). The toothed racks are arranged to drive an output element (15) with their first axial portions (7).

The present invention involves a system and method for grinding herbs, tobacco, marijuana and the like. The herb grinder system herein includes interchangeable and replaceable lower grinder plates that are secured in place with threading, bayonet mounts or the like. The upper and lower grinding plates are provided with blades having a modified diamond shape which provides extremely sharp leading edges regardless of which direction the grip assembly of the grinder housing is rotated. The lower plates are also provided with variations in the size, shape and arrangement of hole sizes through which the ground material is allowed to pass through. This construction provides the user with the ability to control his/her grind size mixture, which may be consistent sized grinds or a mixture of different sized grinds.
