Abstract: Coffee bean grinder (1) comprising at least one grinder module (4), at least one supply of coffee beans (2) as well as a ground coffee dispensing area (6) with a bracket (13), onto which are porta filter (9) to be filled with ground coffee is put for the process of dispensing ground coffee into said porta filter (9), wherein the coffee bean grinder (1) comprises a proximity sensor for detecting the presence of a porta filter (9) on said bracket (13), and wherein said proximity sensor is at least indirectly coupled to a grinder control unit (5), characterised in that said proximity sensor is a contactless proximity sensor (16).

Abstract: A method for controlling an automatic coffee bean grinder (2) which is separate from an automatic coffee brewing machine (1) using ground coffee produced by said coffee bean grinder (2), is shown, wherein a flowmeter sniffer element (15) is located in or at a housing (3) of said coffee brewing machine (1) is capturing the water flow-through information measured by a water flowmeter (5) of said coffee brewing machine (1), and transmits the water flow-through information to a grinder control unit (26) located in the automatic coffee bean grinder (2), and the grinder control unit (26) controls the grinder module (24) as a function of the water flow-through information transmitted from said flowmeter sniffer element (15).

Abstract: 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.
