A grinding chamber of a grinding device for vegetal products suitable to form beverages includes, in its interior, a pair of grinders axially overlapping each other, one of which is rotatable with respect to the other which is kept stationary, a grinder support at least for the rotatable grinder, a motor member connected to the grinder support for setting the rotatable grinder in rotation. The grinding chamber is formed by a first bottom wall, perpendicular to the axis of rotation of the rotatable grinder, adjacent and below the support thereof, and at least a second cylindrical wall, connected axially to the first wall at the peripheral boundary thereof. The grinding chamber also includes a first opening for introducing the product to be ground and with a second opening for discharging the ground product. A labyrinth is provided between the peripheral boundary of first wall and the grinder support.

A grinder appliance includes a body having a housing portion. A grinding assembly is positioned within the housing portion where the grinding assembly is configured to grind whole beans into ground beans. A chute extends between the grinding assembly and a discharge aperture. An ion generator extends through the chute and into a channel defined by the chute. The ion generator includes an attachment feature configured to be coupled to at least one of the body and the chute. At least one pin extends from an end of the attachment feature and into the channel. A power source is coupled to the at least one pin to generate an ion field within the channel to reduce a charge on the ground beans traveling through the chute.

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.

Disclosed in the present invention is a high-precision externally-adjustable coffee grinder, including a main housing, a lifting rod, a grinding assembly and a coarseness adjusting structure, where the coarseness adjusting structure includes an external adjusting ring, an internal driving ring, a transmission gear; the external adjusting ring is sleeved and rotates relative to the main housing; the external adjusting ring is engaged with the internal driving ring through the transmission gear; and the external adjusting ring drives the internal driving ring to rotate to drive the lifting rod to adjust a grinding disc gap. The adjusting precision of the adjusting structure is greatly improved, the advantages of convenient adjustment of the externally-adjustable coffee grinder and clear scale indication of a one-turn coffee grinder are retained, and the problem of low precision of the one-turn adjusting coffee grinder in the prior art is solved.
