An electrically operated coffee grinder of the type provided with a pair of blades operating in a coffee grinding chamber with the capacity to increase or decrease their mutual distance for the purpose of selecting the grain size of the coffee powder to be obtained, wherein the distance between blades of the coffee grinder can be adjusted and displayed.

The present invention discloses a bean grinder container, a bean grinder, and a coffee machine, where the bean grinder container includes a cup body and a grinding disc, the grinding disc is of a hollow structure, a grinding rib is disposed on an inner wall of the grinding disc, a connection assembly is disposed below the cup body, the connection assembly is fixed below the cup body, and the grinding disc is fixedly connected to the connection assembly. The bean grinder includes a bean grinder main machine and the bean grinder container, and a lower portion of the bean grinder container is in butt joint with the bean grinder main machine and is detachably connected to the bean grinder main machine. The coffee machine includes the bean grinder.

The present disclosure surrounds a flat burr grinder with increased ease of maintenance, adjustability, and/or precision as related to the grinding of media such as coffee beans. The apparatus described herein includes a grinding assembly which is optionally configured for disassembly at a location which corresponds to the location of the burrs to allow for easier maintenance and adjustability without affecting the gap between the burrs as last set by the user. An optionally interchangeable pre-breaker auger allows for adjustability of the particulate size of grinding material which is introduced to the burrs for grinding.

A grinding system that includes a grinder attached to a grind size adjustment ring. Also, a potentiometer attached to the grind size adjustment ring, so as to provide a grind size measurement to a controller. The controller selects a grinding duration based upon the selected grind size measured by the potentiometer.

Coffee grinder includes two grinding discs that can be rotated in opposite directions, the axial distance between which defines the degree of grinding of the coffee powder produced. The grinding discs are mounted one over the other within a grinder body, the lower grinding disc being rotatable about a vertical axis of rotation while the upper grinding disc can be adjusted non-rotatably and by an eccentric shaft relative to the lower grinding disc in the direction of the vertical axis of rotation. By rotating the eccentric shaft with a motorized drive, the space between the grinding discs can be changed. This enables almost infinite regulation of the degree of grinding when preparing the coffee.

A coffee grinder has an adjusting device suitable for adjusting a distance between the blades, an adjusting knob rotatably mounted on the body of the coffee grinder in such a way that a rotation of the adjusting knob determines an actuation of the adjusting device and consequently an adjustment of the distance between the blades, and a revolution counter unit mounted on the adjusting knob to count the revolutions of the adjusting knob and give an indication about the revolutions of the adjusting knob to the user.
