A grinder comprises: a receiving container, formed with an accommodation space and an installation space, and the bottom end thereof being extended with a connection ring have a feeding port, and a hollow grinding seat and a fasten ring are respectively and detachably disposed in the feeding port and the connection ring; an electric driving device, detachably disposed in the installation space; and a base, detachably disposed at the bottom end of the receiving container and including a hollow grinding chamber having the interior disposed with a support member with a pivotal shaft, a passive rod is sleeved and linked with a conical grinding disk, the top end and the bottom end of the passive rod are respectively sleeved with the output shaft and the pivotal shaft, thereby allowing the grinding disk to protrude into the grinding seat and forming a gap between the above two.

A coffee bean feeder for feeding coffee beans coming from a coffee bean container to a coffee grinder and, more particularly, a coffee bean feeder for selectively feeding coffee beans coming from a coffee bean container among a plurality of coffee bean containers to a coffee grinder are provided. The coffee bean feeder has an inlet and an outlet, and a rotatable body provided with one or more dosing compartments. By rotating the body of the feeder about its longitudinal axis, a dosing compartment can be brought into alignment with the feeder inlet or with the feeder outlet or with neither of them. A selecting unit comprising one or more of such coffee bean feeders, as well as a coffee machine comprising the selecting unit, are also provided.

The present invention relates to a herb grinder. More particularly it is a compact-pocket size 3 piece or 4 piece grinder chassis including herb grinding compartment, spinning herb chamber floor compartment, nectar/crystal storage area and a rectangular side storage tray which is magnetically inserted into grinder chassis. The herb grinding compartment floor includes static cutting teeth, machined hole opening and central axle socket which runs perpendicular vertically down the center. This grinder further includes a lid and a hand crank embedded in it which when moved, moves all the connected components. The first compartment pulverizes the herbs into small chunks inside the herb grinding compartment, which then flows downward through the hole opening leading the herb to enter spinning chamber floor which then directs the herbs to longitudinal side storage tray.

A herb grinder system may have a tubular housing with a top portion, a bottom portion, an internal bore, and a side wall opening, the top portion having a top surface and a bottom surface, a first set of teeth extending away from the bottom surface of the top portion, a lid rotatably connected to the top surface of the top portion which forms a grinding chamber configured to receive herb, a second set of teeth extending away from an inner surface of the lid into configuration with the first set of teeth, a plurality of apertures being defined by a floor of the grinding chamber which allow herb to exit the grinding chamber, and a collection chamber having a diameter less than that of the tubular housing which is slidably removed from the side wall opening of the tubular housing.

A flower mill assembly grinds vegetation into ground vegetation. The flower mill assembly includes a container defining an opening and an interior chamber for holding vegetation before it is ground and for collecting ground vegetation after the vegetation is ground. A sifting screen is secured to the container within the interior chamber. The sifting screen allows the ground vegetation to pass therethrough while preventing the vegetation from passing therethrough. A knob covers the opening of the container to enclose the interior chamber. A rotor is secured to the knob. The rotor defines a grinding surface, a center axis, and at least one grinding channel, whereby the rotation of the rotor grinds the vegetation disposed adjacent the grinding surface and the at least one grinding channel.
