摘要： A control unit, a pump for supplying infusion water, a boiler for heating the infusion water, an infusion unit, a coffee mill, and a user interface including a selector for a beverage and/or a ground coffee dose. The coffee mill has a hopper for coffee beans, a rotating and a non-rotating grinder, a motor for directly or indirectly driving the rotating grinder, all with capability to adjust the distance between the grinders. A first sensor detects a number of turns and/or speed of the motor and/or of the rotating grinder. A second sensor detects a distance between the grinders. The control unit stores an algorithm for calculating a correct dose of ground coffee, configured to receive the value of ground coffee selected and the distance between the grinders to automatically generate the number of motor turns necessary to obtain the correct dose of ground coffee.

摘要： Coffee grinder for grinding coffee beans, comprising a container or supply element for coffee beans and a grinding device for grinding the coffee beans. The grinding device comprises a first and a second grinding element between which the coffee beans are ground, the distance between the two grinding elements in the grinding process determining the degree of grinding of the ground coffee, and at least one grinding element being driven by a motor. An adjusting element is provided, with which the distance between the two grinding elements can be adjusted by rotating an adjusting element, and a magnetic rotational position sensor, which directly or indirectly determines the absolute rotational position of this adjusting element as a measure of the distance and provides it for the further control of the coffee grinder.

摘要： An apparatus for grinding a mineral includes a head operable to be attached to a bottle. The head includes a radial slider for controlling the coarseness of the grind. The apparatus further includes an inner grinding element, an outer grinding element, a shaft, and a neck sleeve. The inner grinding element is in communication with the head. The outer grinding element is also in communication with the head, wherein the outer grinding element and the inner grinding element are operable to rotate relative to each other. The shaft extends through the inner grinding element and the outer grinding element. The shaft couples with the inner grinding element and comprises a blunt end. The shaft also extends through the neck sleeve, which acts as a spacer between the inner grinding element and the blunt end.

摘要： A coffee grinder has a housing that includes a ring burr, a shaft extending through the ring burr, a frustoconical burr, and an interlocking plug. An internal bore of the frustoconical burr has an upper cylindrical surface adjacent the top end, an interlocking portion adjacent the bottom edge, and a tapered side surface. The interlocking plug is shaped to extend through the internal bore of the frustoconical burr, and includes an upper cylindrical portion that fits through the upper cylindrical surface, and a lower portion that includes a sidewall surface which is also tapered such that the sidewall surface interlocks with the side surface of the frustoconical burr.

摘要： The present invention is an improved method to grind coffee where grinding speed can be adjusted either on demand or according to a programmed profile. By lowering the rotational speed of the grinding burrs, the user can insure more consistent particle size for types of coffee or methods of brewing where it is desirable, or dramatically increase speed for greater productivity. By incorporating a load cell, the grinder is able to identify coffee brewing device and deliver portioned ground coffee according to program settings or user input. The device also features an improved hopper design to reduce waste and ease whole bean removal. More importantly is a new method to calibrate the distance between the grinder mills and to automatically adjust grinder particle size so that a given numerical value is consistent for each grinder and every user.
