A bean grinder having a bean grinding chamber part, a dynamic grinding wheel, a static grinding wheel, and a residue removing plate. The bean grinding chamber part comprises a bean grinding chamber and a powder discharge channel. An inner wall of the bean grinding chamber is provided with a planar first inner wall disposed close to a powder discharge port and located at a rear side of the powder discharge port in a rotation direction of the dynamic grinding wheel. The first inner wall is tangent to a circle of the inner wall of the bean grinding chamber. An inner wall of the powder discharge channel comprises a second inner wall located at the side of the powder discharge port provided with the first inner wall, and the second inner wall is inclined outwards at a given angle with respect to the first inner wall.

Automatic calibration process for electronic grinder-doser apparatuses of coffee in beans provided with an electronic weighing device directly connected to the logic control unit of the apparatus, wherein the grinding times necessary for obtaining the requested dose weight in grams of ground coffee are pre-set, the process being aimed at periodically checking the quantity of coffee actually ground, re-calculating and re-setting the grinding times in the logic unit. The process particularly comprises a first phase (Phase A) of start, a second phase (Phase B) of sampling by multiple short and long detections, a third phase (Phase C) of processing by compensation calculation and a fourth phase (Phase D) of self-adjustment, the second, third and fourth phases (Phases B-D) being totally automatic, that is to say, being sequentially carried out by the electronic grinder-doser apparatus as automatic procedures by the logic control unit.

Actuators and interchangeable cartridges that achieve a grinding or grating different substances without cross-contamination. The actuators and cartridges are disclosed are uniquely designed for ready push-on, push-off mounting in a manner that affords proper alignment of the cartridge in the actuator. The cartridges may include a container portion and a mount portion, each with a grinding element arranged at an output thereof. As the container and mount portions move relative to one another, their respective grinding elements move, achieving a grinding or grating of substances in the container. Various embodiments and variations are disclosed.

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 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.
