A grinder assembly which minimizes deviations in the path of ground material as well as other interfering structure is provided. A receiving chamber is disposed above a grinding mechanism and provides for direct transfer of material to be ground from the outlet aperture of the receiving chamber to the grinding mechanism. The grinding mechanism is driven from above and, therefore, no other structure necessary which may interfere with the ejection of grounds from the grinder assembly. A vacuum-stabilized base plate may also be provided in order to securely and removably mount the grinder assembly to a surface.

A coffee grinder-doser includes a grinder-doser body enclosing a grinding chamber which houses first and second mills configured and mutually positioned to grind coffee beans into powder. An external ring-nut which is gripped and rotated by an operator integrally connects to the first mill. A nut screw with a longitudinal axis, inside the grinding chamber, is engaged with an external thread of the ring-nut to translate the first mill along the longitudinal axis. The ring-nut includes a ring-nut body and indices defining the angular position thereof. The grinder-doser body includes a fixed reference for the indices. The ring-nut is associated with a graduated ring having the indices, and a cover at least partially removable to lock the graduated ring between the cover and the ring-nut. The cover is fixed to the ring-nut body by a partially removable couple for adjusting and locking the angular position of the graduated ring.

A foodstuff preparation device may include a roasting chamber having grinding funnel configured for communicating a foodstuff, having a pre-ground particle size, between two or more grinding stones, such as a first grinding stone and a second grinding stone. A grinding motor may be configured to motivate the foodstuff between the two or more grinding stone so that the foodstuff exits from between a first grinding stone and second grinding stone with a first ground particle size, the first ground particle size smaller than the pre-ground particle size. Generally, the device may be configured to prepare foodstuffs, such as sesame seeds, by roasting and grinding them to produce Tahini, or any other similar prepared food. Optionally, the foodstuff may be communicated into the grinding funnel from a dispensing funnel or from a roasting cavity having a heating element configured to govern the temperature of the roasting cavity.

A electronic grinder includes a main body removably attached to a grinding and dispensing chamber. The top of the main body is sealed by an upper cab and the bottom of the chamber is sealed by an openable lower cap. The main chamber includes a motor connected to a magnetically attached removable blade. The blade extends into the chamber when the grinder is assembled. When the lower cap is closed, the blade grinds material placed in the chamber. When the lower cap is opened, the blade functions as a fan to dispense ground material out of the chamber. The grinder also includes a display, an electronic scale, and an accessory cigarette lighter.

An apparatus for preparing a personal smokable product includes: a grinder section comprising a grinder for grinding plant material; a holder section attachable to the grinder section and comprising a holder receiving a wrapper support for supporting a wrapper for receiving ground plant material when aligned with the grinder; and one or more removably attachable auxiliary modules, which may include a dry herb vaporizer, an oil vaporizer, an audio speaker, and/or a storage compartment. The grinder includes a cutter having wall blades projecting from a chamber-defining wall toward a central axis of the chamber; a motor-driven shaft rotatable about the central axis, and shaft blades projecting radially from the shaft. The grinder includes conical bun members with an adjustable gap for coarseness. Even when the grinder section and the holder section are attached to each other, the wrapper is user-accessible if the holder is in its non-aligned position.

An automatic grinder and a grinding method thereof. The grinder includes a control structure and at least one material container assembly. The control structure includes a driving assembly and a connecting structure connected thereto. The material container assembly includes a material container body (20), a grinding head (22) fixedly connected to the material container body (20), and a grinding sleeve (25) rotatably connected to the grinding head (22). A recess (201) is provided on the material container body (20), engaged with the connecting structure. The grinding head (22) is fitted into the grinding sleeve (25), defining therebetween a material compartment (40) for accommodating a material. The driving assembly drives the material container body (20) to rotate. The material container body (20) drives the grinding head (22) to rotate. The grinding head (22) moves relative to the grinding sleeve (25), such that the material therebetween is ground into powder.

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.
