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.

It it described a roasted coffee bean grinder device comprising a grinding chamber (2), a pair of grinders, one on top of the other, housed within said grinding chamber, one of said grinders being rotatable relative to the other which is kept stationary, a support for at least said rotatable grinder, a drive member (4), connected to said support for rotating said rotatable grinder, an electronic control and command unit (16).

The grinding chamber (2), containing said grinders, has a first opening (5a) for introducing the roasted coffee beans to be ground between the grinders and a second opening for discharging the ground product.

The device includes an apparatus for moistening the beans of the product to be ground, which is adapted to feed a predetermined amount of wetting substance, particularly water, to the roasted coffee beans to be ground, to prevent the formation of electrostatic charges in the ground product and reduce the weight loss in ground coffee with respect to the predetermined weight dose of the beans to be ground. The added dose of wetting substance is determined as a function of the amount of beans to be ground.

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.
