The invention relates to a roasting and grinding apparatus for coffee beans comprising a roasting device (50) and an associated grinding device (60); the roasting device (50) being configured for receiving coffee beans of a certain type that will be roasted, the roasting device (50) comprising reading means (53) to identify the characteristics of the coffee beans dispensed to it, the roasting device (50) further comprising a control unit configuring the roasting profile of the beans according to the characteristics retrieved from the reading means (53) and/or from the characteristics of the beans in a database (51) in this control unit and/or according to the user’s input; the roasted coffee beans being dispensed into a beans container (10, 20), the beans container (10, 20) comprising programmable identification means where product parameters of the roasted coffee beans of a certain type are encoded on it by an encoder (52) in the roasting device; the grinding device (60) comprising one or more housings for receiving one or more beans containers (10, 20); the grinding device (60) comprising a reader (62) to obtain the information of the product parameters of the roasted coffee beans of the one or more beans containers (10, 20); the grinding device (60) further comprising a control unit configured to adapt the grinding size and the quantity of roasted coffee beans to be delivered from the coffee beans containers (10, 20) for obtaining a certain coffee quantity and/ or a certain coffee blend quantity from each beans container to be grinded according to these product parameters and/or according to a recipes database (64), and/or according to the user’s input. The invention further relates to a method for roasting and grinding coffee beans using a roasting and grinding apparatus as the ones described, and to the use of such a roasting and grinding apparatus.

A coffee brewer contains a brewing unit in which coffee grounds having been poured in are compressed by a plunger driven by an actuator. Heated water flows through the compressed coffee grounds. A control device controls the actuator in accordance with signals of an angle of rotation sensor. The control device first moves the plunger against a stop in an ejection position to calibrate the sensor, then moves the plunger by a predetermined distance in a downwards direction into a pouring-in position. Afterwards the control device moves the plunger by a second distance into the brewing position, a length of the predetermined distance and the second distance corresponds to a number of pulses of the sensor which are stored in the memory. The control device subsequently moves the plunger by a third distance back into the ejection position in which the coffee grounds are removed from the plunger.

Disclosures of the present invention describe a coaxial microwave rotary applicator for material processing, mainly comprising: a waveguide unit, a microwave generator connected to one end of the waveguide unit, a bearing unit, a chamber, a rotary shaft, a driver unit, a sampling unit. The bearing unit is connected to the waveguide unit through a non-rotary ring, and the chamber is connected to a rotary ring of the bearing unit, and the microwave generator is configured for supplying a microwave to the chamber. By such arrangements, it is able to uniformly heat a specific material disposed in the chamber by driving the chamber to rotate. It is worth noting that, a user is allowed to clearly observe the processing progress via the sampling unit during the heating process of the specific material.

A modular brewing system is described for providing hot water and managing power to multiple brew tower modules using a single centralized boiler and power management module so as to limit the number of high-power circuits required in a coffeehouse or store. The boiler and power management module manages power of components of the centralized boiler assembly and any brew tower modules connected thereto, including the boiler heaters, the grinder motors, and the brew chamber heaters.

The invention relates to an apparatus (1) for more convenient roasting of coffee. The apparatus (1) in particular facilitates an improved means for collecting the chaffs of the so roasted coffee beans to make the removal of the roasted coffee beans from the apparatus (1) more convenient, in particular when the apparatus (1) is used as a home appliance apparatus. The apparatus (1) is for roasting coffee beans and for collecting chaffs of the so roasted coffee beans. The apparatus (1) comprises: a chamber (10) in which coffee beans can be received for roasting, the chamber (10) comprising an opening (12) for accessing the chamber (10) in order to at least remove coffee beans from the chamber (10), and a chaffs collector (50) for collecting chaffs of the coffee beans, which are roasted by the chamber (10). The chaffs collector (50) is moveably arranged with respect to a specific movement axis in order to be moved between a closed position, in which the chaffs collector (50) covers the opening (12) of the chamber (10) for roasting the coffee beans, and an open position, in which the chaffs collector (50) does not cover the opening (12) of the chamber (10) so that the chamber (10) is accessible via the opening (12) for removing coffee beans from the chamber (10).
