An arrangement for producing personalized coffee comprises a data gathering device for gathering user related data for producing said personalized coffee. The arrangement also comprises plurality a roasting systems, where each of the roasting system comprises hoppers with a selection of coffee bean varieties, a roasting unit for roasting the selected coffee bean varieties, a grinding unit for grinding the roasted coffee bean varieties, and a packaging unit for packaging the roasted and/or grinded coffee bean varieties. Further the arrangement comprises a controlling computer for receiving said user related data for producing said personalized coffee. The controlling computer is configured to form controlling parameters based on said user related data and thereby control the operations of at least one roasting device of said selected roasting system of said at least two roasting systems by said controlling parameters in order to produce said personalized coffee.

The invention relates to a coffee bean container (10, 10) comprising green and/or partially roasted coffee beans, the container comprising: an inner volume (14) where beans are stored; roasting means allowing beans roasting in a certain required degree depending on the original roasting level of the stored beans; at least part or complete grinding means allowing grinding of the beans, once roasted, to a certain grinding size. The roasting means preferably comprise a roasting hollow tube (11) through which hot air at pressure circulates such that coffee beans circulate within the internal container volume and inside the tube (11), creating a fountain effect.

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 coffee preparation machine can include at least one sealed pod containing unroasted green coffee beans, a roasting system that accepts the at least one sealed pod, a grinding system, and a brewing system, where the brewing system, the roasting system, and the grinding system can be housed within a single self-contained unit.

An apparatus for roasting coffee beans comprises a roasting chamber for containing coffee beans. The roasting chamber is positioned within a resonant cavity of a waveguide. A microwave emitter produces microwave energy within the waveguide with one or more stable high intensity microwave regions within the roasting chamber to heat the coffee beans in the roasting chamber to a temperature sufficient to roast the coffee beans. A device configured to move the coffee beans within the one or more high intensity microwave regions is coupled to the roasting chamber.
