Grinder-doser device for coffee beans includes a body which internally houses an electric motor, having a shaft, which is integral in rotation with the lower grinder holder to which the lower grinder is joined, said lower grinder holder, and said lower grinder being housed inside a head which has a horizontal annular seat in the lateral edge, which houses an upper grinder. The upper grinder being formed by a toothed annular portion housed inside a hollow annular portion, which in turn is surrounded by an annular portion, which rests on the annular seat. The flat upper surface of the upper grinder is rectified and collimated with the plane passing through the ends of the teeth of the toothed portion.

A dispenser for a first solid flowable material and a second flowable material, including an actuator for providing rotational motion on a shaft. A first reservoir holds the first material, and a second reservoir holds the second material. A metering unit selectively passes at least one of the first material and the second material. A grinder grinds the at least one of the first material and the second material passed by the metering unit.

A novel device for hand grinding coffee is disclosed. The device preferably includes a base, a stanchion disposed about the base, and a gear box, a burr collar, and a flywheel each extending away from the stanchion. The flywheel includes a handle for turning it. The device further includes a gear mechanism including a main driven shaft. The main driven shaft extends downward from the gear box. There also is a burr mechanism driven by the gear mechanism. The device may include a variable transmission mechanism having a first gear set and a second gear set selectively engageable to drive the main driven shaft. The device may also include a tumbler having a ground chamber. A distribution member is configured to rotate within the ground chamber of the tumbler during operation of the device.

A kitchen appliance for processing food includes a housing, in or on which a drive unit is arranged for driving a processing tool for processing food. The kitchen appliance also includes an actuating mechanism for actuating the drive unit, wherein the actuating mechanism has a moveable switching element arranged outside of the housing. A switch is arranged inside the housing and an opening passes through the housing. The switch is switchable with the switching element for actuating the drive unit such that the switching element is moved relative to the switch, and the kitchen appliance has a sealing element, which forms a seal while closing the opening and transfers the movement of the switching element to the switch.

The present disclosure is directed to systems and apparatus for grinding spices and grains. One system includes a mill for grinding a spice or grain material, comprising a body and a handle rotatably coupled to the body. The handle is also coupled to an input of a speed boost assembly. An output of the speed boost assembly is coupled to a grind assembly, which includes a rasp. The speed boost assembly is configured to cause the rotational frequency of the rasp to be greater than a rotational frequency of the handle.
