The present patent discloses an electric grinder, comprising a shell, a motor assembly, a grinding assembly and a dust cover. The motor assembly and grinding assembly are provided in the shell, and an opening is provided at one end of said shell. The dust cover comprises a cover and a counterweight part, and can open or close the opening of the shell under the gravity of the counterweight part. In the electric grinder provided by the present invention, when the opening of the grinder faces downward, the dust cover can open automatically. When the opening of the grinder faces upward, rotating the dust cover can close and engage with the opening of the dust cover automatically. Thus, the present invention prevents the feed opening of the electric grinder from being exposed to air when the user forgets to close the dust cover.

A coffee bean grinder includes a base internally housing an electric motor and supporting a bell-shaped vessel for containing coffee beans, the bell-shaped vessel being provided lowerly with an exit mouth connected to a grinding chamber housing a grinder rigid with the electric motor shaft, the grinding chamber being provided lowerly with an exit hole, wherein the base is provided, in a position corresponding with the ground coffee exit hole, with a seat for sealed engagement with a container, which is completely closed except for an opening present in the upper surface, and of which the dimensions correspond substantially to the dimensions of the ground coffee exit hole hole, the opening facing the hole when the container is engaged in the seat.

A coffee grinder includes a load cell fixed to a bracket for measuring the weight of coffee powder contained in the filter of a filter holder arranged in a seat of the bracket. The load cell has rear and front portions attached to the bracket, and a holder attached to a base, wherein the load cell is mounted on the support, so that the rear portion of the load cell is attached to the rear portion of the support, and the front portion of the load cell is spaced away from the front portion of the support to leave a gap between the front portion of the support and the front portion of the load cell. The width of the gap is such to allow for a downward bending of the front portion of the load cell that is lower than a maximum load limit of the load cell.

A coffee grinder suitable for home use can include a housing that receives coffee beans, a grinding component within the housing, a removable container that receives coffee grounds dispensed from the grinding component, and a base located beneath the grinding component that supports the container. Magnetic components in the base and removable container can optimally align the container when placed atop the base. A knocker system can dislodge ground coffee residue into the container when actuated. An intelligent drive system can utilize feedback to drive the grinding component at a constant speed to minimize coffee grounds size variances. A grinds chamber in the housing can define an asymmetrical cross-sectional geometry. An auger that drives the grinding component can have an outer thread that forces coffee beans through the grinds chamber, and a grinds chamber housing can include a protective shoulder that covers a lead-in portion of the outer thread.

An apparatus for dosing coffee beans for the purpose of selecting a metered quantity to be ground comprises a portioning device with a metering chamber having a receiving volume for receiving the coffee beans. The receiving volume is variable. Preferably, the setting of the metered quantity is performed mechanically, wherein the effect of the settings on the portioning device takes place mechanically. Preferably, the apparatus comprises a setting ring for manually adjustment of the metered quantity.

Grinders, analyzers, and related technologies are described herein. The grinders can hold foodstuff that is periodically ground. The analyzers can analyze the foodstuff to determine information about the state of the foodstuff. Algorithms can be used to determine how to process the foodstuff, how to use the foodstuff, and/or when to discard the foodstuff. The grinder can be a portable, rechargeable electric coffee grinder configured to monitor the freshness of the coffee beans. When coffee beans become stale, they can be discarded and the coffee grinder can be refilled with fresh coffee beans.
